Résumé :

Since man has domesticated plants and improved them, he has used every means at his disposal to do so. During the last 60 years, with the progress of knowledge in biology, especially in genetics, new tools, called "green biotechnologies", have appeared and are increasingly used. A working group of the French Academy of Agriculture has evaluated the use of green biotechnologies and identified their development potential by 2030 to meet the triple challenge of agriculture: coping with food security, respecting the environment and adapting to climate change. This report presents original information from a 2016 survey of 79 French plant breeding centres including 23 private companies and three public research centres of INRA (Institut National de la Recherche Agronomique; French National Institute for Agricultural Research), who were asked about the use of these tools.

Résumé :

In accordance with the European concept of GVC, the study identified key players in the biotechnology market and attempted to analyze the degree of incorporation of Siberian biotechnology companies into global value chains. Preliminary results showed that domestic companies are poorly embedded in global value chains. In the markets of “red” biotechnologies, this is the import of primary highly purified / low-purified substances, depending on the scope of use in the final product and the export of high-tech R & D services. The weak link of our market in GVC is engineering and distribution. In the markets of "green" biotechnology, in which segments of genetic engineering can be distinguished (breeding new plant varieties, GM crops), biotechnologies for livestock and plant growing, high competitiveness and export potential have so far formed only in the market of biological plant protection products.

Résumé :

Contamination of marine sediments by organic and/or inorganic compounds represents one of the most critical problems in marine environments. This issue affects not only biodiversity but also ecosystems, with negative impacts on sea water quality. The scientific community and the European Commission have recently discussed marine environment and ecosystem protection and restoration by sustainable green technologies among the main objectives of their scientific programmes. One of the primary goals of sustainable restoration and remediation of contaminated marine sediments is research regarding new biotechnologies employable in the decontamination of marine sediments, to consider sediments as a resource in many fields such as industry. In this context, microorganisms—in particular, fungi and bacteria—play a central and crucial role as the best tools of sustainable and green remediation processes. This review, carried out in the framework of the Interreg IT-FR Maritime GEREMIA Project, collects and shows the bioremediation and mycoremediation studies carried out on marine sediments contaminated with ecotoxic metals and organic pollutants. This work evidences the potentialities and limiting factors of these biotechnologies and outlines the possible future scenarios of the bioremediation of marine sediments, and also highlights the opportunities of an integrated approach that involves fungi and bacteria together.

Résumé :

The regional context of smart specialization continues to be in the focus of academic discussions as the innovative potential of regions in Bulgaria is being determined. The aim of the present work is to identify innovative practices in one of the leading thematic areas – “Healthy living industry and biotechnologies” during the period of 2014-2019 in a selected region. The object of research is the region of Yambol listed in the National Strategy for Smart Specialization in the Republic of Bulgaria as a promising region in the thematic area “Healthy living industry and biotechnologies”. We have applied methods of regional economic analysis based on objective statistical data. Regional analysis has been complemented with a survey to reflect the subjective viewpoint of stakeholder representatives. The survey and the analysis of the collected information prove the presence of potential in the region of Yambol for expanding organic production in the food industry and generating “green energy” in the energetics sector.

Résumé :

One of the main targets of sustainable development is the reduction of environmental, social, and economic negative externalities associated with the production of foods and beverages. Those externalities occur at different stages of food chains, from the farm to the fork, with deleterious impacts to different extents. Increasing evidence testifies to the potential of microbial-based solutions and fermentative processes as mitigating strategies to reduce negative externalities in food systems. In several cases, innovative solutions might find in situ applications from the farm to the fork, including advances in food matrices by means of tailored fermentative processes. This viewpoint recalls the attention on microbial biotechnologies as a field of bioeconomy and of ‘green’ innovations to improve sustainability and resilience of agri-food systems alleviating environmental, economic, and social undesired externalities. We argue that food scientists could systematically consider the potential of microbes as ‘mitigating agents’ in all research and development activities dealing with fermentation and microbial-based biotechnologies in the agri-food sector. This aims to conciliate process and product innovations with a development respectful of future generations’ needs and with the aptitude of the systems to overcome global challenges.

Résumé :

The paper provides the evaluation of the efficiency of financing the regional policy promotion activities from the EU structural funds and efficiency of funding of national and regional smart specialization strategies’ priorities in 2014-2020. It determines 6 key smart specialization domains among 216 RIS3 of national and regional (NUTS 2) levels: agriculture, food, and biotechnologies; green technologies, energy; transport, mobility, logistics; ICT; life sciences, biotechnologies, pharmacy, biotechnologies; material sciences and intellectual production. Four hypotheses on the close relationship between the investment volumes, directions, and results of their use are empirically verified. The results of the applied correlation analysis show the close relationship between the volumes of funding of the smart-specialization activities and the paces of agricultural output per capita with three clusters of countries by the distribution of funding by the strategic priorities. Regarding the other smart specialization priorities – “environmental technologies, energy efficiency” and “transport, mobility, logistics”, the dependence between the funding from the European Structural and Investment Funds and reducing CO2 emissions from new vehicles is proven. Support of strategic priorities “material science” and “smart production” by European Structural and Investment Funds in 2014-2020 is characterized by growing GRP volumes per capita with clear differences between the developed and average-level EU countries. The reasonability of supporting the implementation of the smart-priority “medicine, pharmacy, healthcare” in most RIS3 of EU countries and the substantial correlation of financial support from EU funds with the paces of state expenses on healthcare increase is substantiated. The conclusions about the efficiency of selected priorities, their high convergence ability, and the capacity to form transnational cooperation are made.

Résumé :

The question of nature conservation became one of the most important in the world. It especially concerns to the countries with dry climate, such as Armenia, where auto recovery possibility of forests is excessively low. Gradual disappearance of forests, green areas is due to human non-competent acting, climate change, which aggravates present ecological crisis. One of the important steps for solution of this problem is the recovery of forests, green areas that requires the existence of huge amount of saplings. The use of open-air hydroponics is one of the best versions to receive healthy, qualify saplings. We studied and developed open-air hydroponic methods and biotechnologies of cultivation of 25 species of tree-shrubs important for the landscaping and forest recovery. There was studied the influence of nutrition solution offered by Davtyan G.S. and used in our Institute many years and its modified variants with the changes of main nutrients elements ratio on the biometric parameters of plants. Received results showed that saplings grown in open-air hydroponics conditions have strong root system, provide high rooting, which is very important in the recovery of forests, green areas, especially today’s ecological critical conditions of forest zones.

Résumé :

The CO2 global average concentration has grown at an alarming rate in the last decade reaching 413 ppm in July 2021, positioning as the primary driver of climate change. The production of the major plastic materials globally produced still rely on fossil fuels, contributing to the release of CO2 in the atmosphere. It is in this contest, that bioplastic industry, particularly PHAs production brings many ecological advantages. PHAs are microbial synthetized polyesters polymers which are both biobased and biodegradable. They are versatile materials, whose properties, hence their applications, depend on their monomer composition, molecular weight and microstructure. This work proposed a more cost-effective and novelty approach, analysing the possibility to produce PHAs by C. aurantiacus, a photosynthetic non-sulphur green bacterium, which has a highly metabolic versatility. In fact, C. aurantiacus can grow in aerobic and anaerobic conditions, heterotrophically with several organic sources and autotrophically with CO2 only as the sole carbon. This was an exploratory work with the aim to evaluate the bacterium capacity to accumulate PHA under anaerobic conditions. Furthermore, new methodologies needed to be implemented and basic operating conditions were tested such as the inoculum-medium ratio, the correlation between OD and cdw and the state of the inoculum. Its growth was first characterized in a rich medium with glycyl-glycine and sulphide, different light intensities and temperatures. Meanwhile, it was possible to evaluate different media impact on its growth, PHA accumulating capacity and pigment synthesis, observing promising results from inorganic media and mixotrophic growth. Moreover, new microorganisms have been isolated from phototrophic mixed culture bioreactor to enlarge the laboratory library of phototrophic microorganisms capable of producing PHAs from inorganic carbon source, revealing an almond-shape purple bacteria able to accumulate PHA.

Résumé :

Le but de cette étude est d’évaluer l’utilisation de la chromatographie préparative dans le cadre de la conception d’un procédé de purification d’acides organiques. Les acides principalement étudiés sont les acides lactique et succinique. Ils sont produits par fermentation et utilisés depuis longtemps dans l’industrie comme additifs. Ils sont aussi identifiés comme des molécules plateformes très intéressantes pour le développement de la chimie verte, à partir de carbone renouvelable. En particulier, ils constituent des monomères pour l’industrie des bioplastiques. A la différence des utilisations historiques, ce type d’application requière des niveaux de pureté beaucoup plus importants. Ces puretés sont atteintes via des étapes supplémentaires d’extraction liquide-liquide, de distillation et/ou de cristallisation. Nous avons cherché à évaluer si la mise en œuvre de la chromatographie préparative pouvait permettre d’atteindre les spécifications requises. Pour cela, la chromatographie a été étudiée en détails en tant qu’opération unitaire, afin de mieux comprendre les mécanismes de séparation des composés étudiés et les paramètres de mise en œuvre. Deux types de résine ont été principalement utilisés, une cationique forte et une anionique forte. Dans un premier temps, l’étude thermodynamique de l’adsorption de trois acides organiques en solution pure a été réalisée. Elle a révélé un comportement très différent pour les deux résines : l’adsorption sur la résine cationique forte est assez linéaire alors que sur l’anionique forte, elle est fortement non linéaire et suit un modèle de Langmuir. L’influence de la vitesse sur la forme des pics et donc la dispersion pendant la séparation a ensuite été étudiée. Il a été montré que l’efficacité de la colonne diminue linéairement avec la vitesse d’élution, conformément au modèle de Van Deemter. Il a aussi été mis en évidence que la pente de cette droite est la même à l’échelle laboratoire et sur le pilote à une échelle dix fois plus grande. Elle peut ainsi permettre de prévoir l’évolution de l’efficacité de la colonne au changement d’échelle. Des solutions en mélange synthétiques et réels ont été étudiées, afin d’évaluer l’influence sur la séparation des paramètres opératoires, tels que la charge, la concentration de l’alimentation, le pH… 2 Sur la résine anionique, une première modélisation a été effectuée à partir de ces résultats expérimentaux. Elle a permis de mettre en évidence, qu’un mécanisme d’adsorption de type Langmuir ne suffit pas à expliquer la forme et la position des pics. Nous avons supposé qu’un mécanisme d’échange d’ions de la forme dissociée des acides organiques pourrait aussi entrer en jeu. Cet échange aurait un impact important sur la forme et la position des pics, bien que les acides organiques soient très majoritairement sous leur forme neutre. Les séparations mises en évidence à l’échelle laboratoire ont été validées à l’échelle pilote en chromatographie continue ISMB. Il a été montré que la résine anionique permet d’atteindre une plus grande pureté que la résine cationique avec une productivité similaire. Un procédé complet de purification a pu être testé avec de l’acide succinique, mettant en jeu une acidification par électrodialyse bipolaire, une concentration par osmose inverse, une séparation par chromatographie préparative sur résine anionique forte et une décoloration par nanofiltration. Le produit a ensuite été cristallisé afin de se comparer à un produit industriel. Le produit obtenu est proche des spécifications attendues et est plutôt meilleur que le produit industriel. Une étape supplémentaire d’échange d’ions aurait vraisemblablement permis d’obtenir des cristaux de grade polymère. Nous avons donc montré que la chromatographie a sa place dans un procédé de purification d’acides organiques, dans le but d’obtenir une très haute pureté
The objective of this study is to evaluate the use of preparative chromatography in the context of the elaboration and optimization of an innovative purification process of organic acids from biotechnology. Lactic and succinic acids were mainly studied. They are produced by fermentation and used in industry as additive, for a long time. They are identified as promising building blocks for green chemistry development, from renewable carbon. In particular, they are monomers for bioplastic industry. Unlike historical utilizations, this new type of application requires much higher purity levels. Those purities are currently obtained by additional purification steps, like liquid-liquid extraction, distillation and/or crystallization. We tried to evaluate if the required specifications may be reached by the implementation of preparative chromatography. For this chromatography was studied in details as unitary operation, in order to better understand separation mechanisms of studied compounds and implementation parameters. Two resin types were mainly used, a strong cationic one and a strong anionic one. Firstly, thermodynamic study of the adsorption of three organic acids in pure solution was performed. It revealed very different performances for both resins: adsorption on strong cationic resin is quite linear, whereas on strong anionic one adsorption is strongly nonlinear and fits with Langmuir model. Elution velocity influence on peak shape and so on dispersion was then studied. Column efficiency decreases linearly with elution velocity, accordingly to Van Deemter model. It was shown that the line slope was identical at lab scale and on a pilot ten times bigger. Then it may be used to predict column efficiency evolution during scale-up. Mixing solutions from synthetic or real origin were studied, to evaluate operational parameter influence on the separation, as load, feed concentration, pH… On the strong anionic resin, a first modeling was developed for experimental results. It highlighted that Langmuir type adsorption mechanism is not able to explain peak shape and position. We supposed that an ion exchange mechanism with the organic acid dissociated part may happen. This exchange may have a significant impact on peak shape and position, even if organic acids are mainly in molecular form, because of a low work pH. 4 Separations established at lab scale were validated at pilot scale in continuous chromatography ISMB. It was demonstrated that the anionic resin allows to reach a higher productivity than the cationic one, with a similar productivity. A complete purification process was tested with succinic acid, using bipolar electrodialysis acidification, reverse osmosis concentration, preparative chromatography separation with a strong anionic resin and nanofiltration discoloration. Product was then crystallized, to be compared to an industrial product. Our crystals were close to waited specifications and relatively better than the industrial ones. An additional ion exchange step could have allows to reach polymer grade. We show that chromatography is useful in an organic acid purification process, in order to reach a very high purity

Résumé :

Les microalgues sont l’une des ressources renouvelables les plus prometteuses pouvant constituer une alimentation durable future. Grâce à leur diversité de métabolisme, ces microorganismes sont capables de synthétiser une vaste gamme de composés d’intérêt à haute valeur nutritionnelle. Cependant, leur consommation reste limitée du fait de leurs caractéristiques organoleptiques intrinsèques peu attrayantes. Afin de répondre à cette problématique et de lever les verrous, les travaux de cette thèse ont porté sur la mise au point d’un procédé de production d’ingrédient alimentaire à partir de spiruline.Une méthode verte et innovante faisant intervenir la technologie ultrasonore pour l'extraction de protéines à partir d'Arthrospira platensis a été proposée dans une première partie. Il s’agit de la manothermosonication (MTS). Le recours à un plan d’expérience a permis d’optimiser les paramètres d’extraction ; et une modélisation mathématique ainsi que des investigations microscopiques ont mené à une compréhension des phénomènes de transfert de masse d’une part et des effets structurels des ultrasons sur les filaments de spiruline d’autre part. Selon les résultats expérimentaux, la MTS a permis d'obtenir 229 % de protéines en plus (28,42 ± 1,15 g / 100 g MS) par rapport au procédé classique sans ultrasons (8,63 ± 1,15 g / 100 g MS). Avec 28,42 g de protéines pour 100 g de spiruline dans l'extrait, un taux de récupération des protéines de 50 % a été atteint en 6 minutes effectives avec un procédé MTS continu. Partant de ces résultats prometteurs, des pistes d’extrapolation ont été étudiées afin de proposer des outils d’aide à la décision pour l’industrialisation du procédé. Ainsi une procédure d’analyse des risques (HACCP & HAZOP), une étude de coût ainsi que l’impact environnemental du procédé ont été développés dans une seconde partie de ces travaux. Enfin, des voies de valorisation des co-produits d’extraction ont été présentées dans une approche de bioraffinerie
Microalgae are one of the most promising renewable resource for future sustainable food. Thanks to their diversity of metabolism, these microorganisms can synthesize a wide range of compounds of interest with high nutritional value. However, their consumption remains limited because of their intrinsic organoleptic characteristics unattractive. To tackle this problem and to overcome these barriers, this thesis was focused on the development of a production process of food ingredient from spirulina.A green and innovative method using ultrasonic technology for the extraction of proteins from Arthrospira platensis was proposed in a first part. This is the manothermosonication (MTS). The use of an experimental plan made it possible to optimize extraction parameters; and mathematical modeling and microscopic investigations led to an understanding of the mass transfer phenomena on the one hand, and the structural effects of ultrasound on spirulina filaments on the other hand. According to the experimental results, MTS allowed to obtain 229 % more proteins (28.42 ± 1.15 g / 100 g DW) compared to the conventional method without ultrasound (8.63 ± 1.15 g / 100 g DW). With 28.42 g of protein per 100 g of spirulina in the extract, a protein recovery rate of 50% was achieved in 6 minutes with a continuous MTS process. Based on these promising results, extrapolation tracks have been studied in order to propose decision support tools for process industrialization. Thus, a risk analysis procedure (HACCP & HAZOP), a cost study as well as the environmental impact of the process were developed in a second part of this work. Lastly, ways of exploiting by-products have been presented in a biorefinery approach

Résumé :

Les rouilles vertes sont des hydroxysels mixtes Fe(II)-Fe(III) présents dans les sols hydromorphes sous forme de fougérite. Elles sont connues pour être capable de réduire des polluants organiques et métalliques. Les rouilles vertes peuvent être produites à partir de la bioréduction de lépidocrocite [gamma]-FeOOH par Shewanella putrefaciens, une bactérie ferriréductrice. En vue de comprendre leur formation dans l'environnement et d'utiliser leur réactivité dans la mise en place, à terme, d'un système de dépollution des sols et des eaux (colonne de sable), nous avons étudié leur formation dans un système en batch en présence d'une phase siliceuse (sable et acide silicique) et en présence de polymères organiques synthétiques (polyacrylate PAA et polyacrylamide PAM) afin de mimer la présence des corps bactériens. La silice est les polymères apparaissent comme de bons agents stabilisateurs, favorables à la formation des rouilles vertes. Les rouilles vertes formées en présence de ces agents stabilisateurs conservent leur capacité réductrice vis-à-vis d'un polluant organique, le rouge de méthyle et d'un polluant métallique, le mercure Hg2+. Nous avons ensuite transposé notre système en batch dans une colonne de sable + lépidocrocite [gamma]-FeOOH, soumise à un régime hydrodynamique. Nous avons réussi à former et à caractériser une rouille verte comme minéral secondaire de la bioréduction de la lépidocrocite par Shewanella putrefaciens
Green rusts are mixed species Fe(II)-Fe(III) present in hydromorphic soils as fougerite. They are capable to reduce organic and metallic pollutants. Green rusts may be produced from the bioreduction of lepidocrocite [gamma]-FeOOH by Shewanella putrefaciens, a dissimilatory iron reducing bacteria. In order to understand their formation routes in the environment and eventually, use their reactivity in a system for soil and water remediation (sand column), we studied their formation in a batch system with silica phase (quartz sand and silicic acid) and with two organic polymers (PAA polyacrylate and polyacrylamide PAM).The silica polymers appear to be good stabilizers, favorable to the formation of green rusts. Green rusts formed in the presence of the stabilizing agents retain their reductive capacity toward an organic pollutant, methyl red and a metallic pollutant, mercury Hg2+. Then, we have transposed our system in a flow through column of sand + lepidocrocite [gamma]-FeOOH. The carbonate green rust was formed and identified as secondary mineral of lepidocrocite bioreduction by Shewanella putrefaciens

Résumé :

Biotechnology is the science that studies and modifies the biological system in which we are living, mainly using modern technologies now, even if Biotechnology, in one form or another, has flourished since prehistoric times (Fig.1). Some examples are breeding of animals, fruit juices fermentation into wine or malt and hops into beer, milk conversion into cheese or yogurt and production of rised bread (Pamela Peters, 1993). With the observation of the plants, the farmers started to improve crops, for example for their highest yield, or for resistance during periods of drought or disease; subsequently they managed to produce future generations with these same characteristics. Through several years of careful seed selection, farmers could maintain and strengthen such desirable traits. The possibilities for improving plants expanded as a result of Gregor Mendel's investigations in the mid-1860s of hereditary traits in peas. Speaking instead of microbes for health, Buchner in 1897 discovered that enzymes extracted from yeast are effective in converting sugar into alcohol and Alexander Fleming in 1928 discovered penicillin, an antibiotic derived from the mold Penicillium. However, the revolution in understanding the chemical basis of cell function that stemmed from the post-first world war emergence of molecular biology was still to come. It was this exciting phase of bioscience that led to the recent explosive development of biotechnology (Biotechnology Industry Organization, 1989, 1990). Today this science, via the combined use of biochemical, physical and molecular approaches, studies micro-organisms, plants, animals and organic and inorganic materials with the purpose of improving the environment in which we are living. Biotechnologies and its applications have greatly improved during the last thirty years due to the development of fast and new genetics and molecular tools. For example the possibility to insert a foreign gene into the genome of a living organism, Recombinant DNA strategy, trusted scientific research and brought to paramount results. In 1978, in the laboratory of Herbert Boyer at the University of California at San Francisco, for example, a synthetic version of the human insulin gene was constructed and inserted into the genome of the bacterium Escherichia Coli; the same bacterium species used by Jacob and Monod to study the bacterial Lac operon. Since then, the trickle of biotechnological developments has swollen into a broad flow of diagnostic and therapeutic tools, accompanied by ever faster and more powerful DNA sequencing and cloning techniques. Biotechnology is actually involved in several research fields, staring from biomedical applications (i.e., the study of new vaccines or the characterization and the cure of new diseases), agricultural problems (the genetic improvement of plant, e.g., for the resistance to some factors, such as stress, insects and diseases) to end with industrial solutions (e.g. the development of new organisms that can produce improved alimentary products from a nutritional side). These goals can be achieved by adopting some basic techniques, which need to be continuously improved. The topic of this work is the development and the study of a number of the techniques used in genomics and proteomics research to increase the knowledge of molecular pathways and processes present into the cell, which are useful to biotechnology applications.

Résumé :

In the ‘Fifth Gene Technology Report’, renowned experts provide an overview of current developments and their applications in the dynamically evolving research field of gene and biotechnologies. They examine, among other topics, genetic diagnostics, somatic gene therapy, the development of vaccines, stem cell and organoid research, green gene technology, synthetic biology, gene drives, genome editing, epigenetics and single cell analysis. In addition to reporting on the current state of affairs in this field, the authors also discuss society’s perception of gene technologies and ethical and legal issues relating to them, such as genome edit-ing, cerebral organoids and big data in personalised medicine. Moreover, the interdisciplinary task force ‘Gentechnologiebericht’ (Gene Technology Report) offers recommendations on action that could be taken in relation to the key issues.

Résumé :

Carbon nanotubes (CNTs) are a unique carbon material with physical, chemical, mechanical, optical, structural, and electrical characteristics researched and tested for a wide range of uses. The safeguards of environmental health have been identified as one of the most critical sustainability goals in recent decades. When it concerns identifying atmospheric toxins, carbon nanotube-based detectors offer great sensibility and precision, along with carbon nanotubes displaying the ability for adsorption to remove impurities with great rates and excellent amelioration competency. Carbon nanotubes have made essential contributions to a responsible future in wastewater treatment, air pollution management, biotechnologies, nano sensors, and sorbents. Carbon nanotubes are also utilized as a reinforcing material in green nanocomposites, which are essential for achieving desired characteristics and are ecologically benign. The utilisation of carbon nanotubes as hybrid filters, nano sensors, sorbents, and other materials is covered in this chapter, as well as its advantages for the environment.
