Annotation:

Le crime contre l’humanité appliqué devant les juridictions françaises est un exemple du fractionnement du droit international pénal. Il y a 15 ans, il existait déjà plusieurs définitions de ce crime. Aujourd’hui, la situation s’est encore aggravée avec l’entrée en vigueur de nouvelles définitions qui se sont ajoutées aux précédentes. La pratique de cette règle du droit international est également marquée par un fractionnement. En effet, il apparaît un régime différent selon que la communauté internationale désigne, ou ne désigne pas, des crimes à poursuivre. Pour éviter ce phénomène de fractionnement en droit français (droit écrit), comment appréhender les caractères du droit international pénal (droit coutumier et impératif) ?

Annotation:

Lignocellulose consists of cellulose, hemicellulose, and lignin and is a sustainable feedstock for a biorefinery to generate marketable biomaterials like biofuels and platform chemicals. Enormous tons of lignocellulose are obtained from agricultural waste, but a few tons are utilized due to a lack of awareness of the biotechnological importance of lignocellulose. Underutilizing lignocellulose could also be linked to the incomplete use of cellulose and hemicellulose in biotransformation into new products. Utilizing lignocellulose in producing value-added products alleviates agricultural waste disposal management challenges. It also reduces the emission of toxic substances into the environment, which promotes a sustainable development goal and contributes to circular economy development and economic growth. This review broadly focused on lignocellulose in the production of high-value products. The aspects that were discussed included: (i) sources of lignocellulosic biomass; (ii) conversion of lignocellulosic biomass into value-added products; and (iii) various bio-based products obtained from lignocellulose. Additionally, several challenges in upcycling lignocellulose and alleviation strategies were discussed. This review also suggested prospects using lignocellulose to replace polystyrene packaging with lignin-based packaging products, the production of crafts and interior decorations using lignin, nanolignin in producing environmental biosensors and biomimetic sensors, and processing cellulose and hemicellulose with the addition of nutritional supplements to meet dietary requirements in animal feeding.

Lignocellulose materials, such as bamboo, rattan, and wood, have been largely used for furniture and crafts. On the other hand, the utilization of lignocellulose-like materials, which have a similar texture and appearance to those from nature, has been increasing recently due to their superior durability. This research aimed to identify the lignocellulose-like material using spectroscopy analysis, such as Raman and Near Infrared (NIR) which is well-known as a non-destructive, quick, and accurate approach for material identification. We investigated 4 types of lignocellulose-like materials that were provided by Dewan Serat Indonesia (The Indonesian Fiber Council) from an industry that produces them. The NIR analysis was performed at wavenumbers 10,000-4,000 cm-1. The natural lignocellulose (bamboo and wood) and the polymers (polyethylene and polyproline) were used as standards. Raman analysis was further employed to identify the composition of selected lignocellulose-like materials by comparing their spectra with the library software. The results showed that the original NIR spectra of lignocellulose-like and those natural materials were different, indicating that the NIR analysis can differentiate those materials. The NIR spectra of lignocellulose-like materials were similar to those of polyethylene spectra. Those lignocellulose-like were also identified as polyethylene due to the similarity of the Raman spectra and their library spectra.

Annotation:

The stubborn and complex structure of lignocellulose hinders the valorization of each component of cellulose, hemicellulose, and lignin in the biorefinery industries. Therefore, efficient pretreatment is an essential and prerequisite step for lignocellulose biorefinery. Recently, a considerable number of studies have focused on peroxyacetic acid (PAA) pretreatment in lignocellulose fractionation and some breakthroughs have been achieved in recent decades. In this article, we aim to highlight the challenges of PAA pretreatment and propose a roadmap towards lignocellulose fractionation by PAA for future research. As a novel promising pretreatment method towards lignocellulosic fractionation, PAA is a strong oxidizing agent that can selectively remove lignin and hemicellulose from lignocellulose, retaining intact cellulose for downstream upgrading. PAA in lignocellulose pretreatment can be divided into commercial PAA, chemical activation PAA, and enzymatic in-situ generation of PAA. Each PAA for lignocellulose fractionation shows its own advantages and disadvantages. To meet the theme of green chemistry, enzymatic in-situ generation of PAA has aroused a great deal of enthusiasm in lignocellulose fractionation. Furthermore, mass balance and techno-economic analyses are discussed in order to evaluate the feasibility of PAA pretreatment in lignocellulose fractionation. Ultimately, some perspectives and opportunities are proposed to address the existing limitations in PAA pretreatment towards biomass biorefinery valorization. In summary, from the views of green chemistry, enzymatic in-situ generation of PAA will become a cutting-edge topic research in the lignocellulose fractionation in future.

Annotation:

Fourteen Streptomyces strains known to degrade lignocellulose were screened for their ability to decolorize three anthron-type dyes: Remazol Brilliant Blue R (RBBR), blue poly(vinylamine) sulfonate – anthraquinone dye (Poly B-411), and red poly(vinylamine) sulfonate – anthrapyridone dye (Poly R-478). The relationships between efficiency of dye decolorization and capacity to attack lignocellulose were examined. Good correlation was found between lignocellulose weight losses observed during previous solid-state fermentation assays and the ability to decolorize RBBR and Poly B-411. A poor correlation was observed between Poly R-478 decolorizing activity and lignocellulose-degrading ability. The presence of corn stover lignocellulose in the culture broth enhanced decolorization of the dye by all but one of the strains. The enhancement was thought to involve the increased production of extracellular peroxidases by cultures growing on lignocellulose. The results on oxidation of the three dyes by a commercial horseradish peroxidase indicate that RBBR and Poly B-411 are suitable substrates for analyzing production of peroxidases by Streptomyces spp., while no decolorization of Poly R-478 was observed under the conditions used. However, Poly R-478 decolorizing activity of the Streptomyces may reflect the activity of other enzymes involved in the complex process of lignocellulose degradation. Key words: Streptomyces, lignocellulose, degradation, dye, decolorization.

Annotation:

The presence of synthetic dye contamination produced from the batik industry encourages research to overcome it through the adsorption method using a smart adsorbent, in this case an adsorbent that has several active groups. This study aims to examine the adsorbent of lignocellulose sulfonate based on bagasse waste for some textile dyes used in the batik industry. The synthesis of lignocellulose sulfonate was carried out through several steps such as extraction and activation using Na2SO3 and NaHCO3. The resulting products were then characterized using FTIR and SEM apparatures and applied them as an adsorbent for Remazol Red RB and Indanthrene Blue RS dyes. The adsorption test was carried out using bagasse, lignocellulose, and lignocellulose sulfonate adsorbents at a solution concentration of 50 ppm with variations in contact time of 5, 10, 20, 40, 80, and 160 minutes. The remaining dye content in the solution was then tested using a UV-Vis Spectrophotometer. From the experimental results, it is known that lignocellulose sulfonate, lignocellulose, and bagasse are able to absorb Remazol Red RB dye, respectively, by 84.41%, 63.87% and 61.52%. While for Indanthrene Blue RS dye, the largest absorption was found in lignocellulose sulfonate adsorbents of 56.35%, lignocellulose 50.72%, and baggase 45.93%. The highest adsorption capacity was found in the lignocellulosic sulfonate adsorbent, namely 42.2081 ppm for Remazol Red RB adsorption and 28.1771 ppm for Indanthrene Blue RS dye.

L'effet de l'azote pendant l'irradiation de pupes de Glossina tachinoides ainsi que le fractionnement des doses d'irradiation, ont été étudiés au milieu de la phase pupale. L'effet protecteur de l'azote contre des irradiations de 10 à 80 Gy de pupes âgées de 15 à 20 jours a été démontré par l'accroissement du taux global d'éclosion, par des niveaux plus élevés de fertilité résiduelle chez les mâles et par des durées de vie plus longues. La stérilité des màles traités par doses fractionnées séparées par 1 ou 2 jours a été identique à celle des mâles traités par une dose unique au 15e j après larviposition ; mais le taux de mutations létales induites était diminué pour des doses fractionnées séparées par un intervalle de 5 jours. La fécondité des femelles a été réduite lors du fractionnement de la dose d'irradiation à intervalle de 1 et 2 jours. Une stérilité complète a été obtenue chez les pupes femelles lorsque l'intervalle entre les doses fractionnées était de 5 jours, indépendamment de la dose utilisée.

Abstract Lignocellulose biomass was a potential feedstock for biobased chemicals substituting fossil-based chemicals. Oil Palm Empty Fruit Bunch (EFB) is the largest lignocellulose biomass from oil palm waste. Lignocellulose contains cellulose, hemicellulose and lignin. Pretreatment is one of the steps in the bioconversion of lignocellulose material. Pretreatment aims to reduce lignin in lignocellulose because lignin can inhibit biomass conversion. The objection of this research is to conduct pretreatment by deep eutectic solvent (DES). DES is the green solvent widely used for biomass conversion. The pretreatment process was conducted at various temperatures and processing times. The delignification of EFB by using DES in 100°C, 120°C, and 150°C pretreatment temperature was 30.67%, 40.60%, and 44.05% respectively. This pretreated-EFB can be used further for biobased chemicals such as glucose, ethanol, or furfural.

Il est maintenant reconnu que la mesure de la concentration totale d’un élément ne permet pas d’obtenir d’information fiable sur son impact environnemental et sa toxicité, ces éléments pouvant être présents sous différentes formes chimiques ou à l’état de nanoparticules (NPs). Il est alors nécessaire de faire appel à des techniques de fractionnement en taille pour les NPs ou à des analyses de spéciation permettant d'identifier et doser les différentes formes chimiques des éléments. Cette approche nécessite de disposer de protocoles d’échantillonnage, de conservation et de préparation d’échantillon stricts qui ne modifient pas la répartition des formes chimiques, notamment. Étant donné les nouvelles exigences des normes, cette approche nécessite également des outils analytiques de plus en plus précis, sensibles et robustes. Le couplage de techniques séparatives basées sur la chromatographie (liquide ou gazeuse) ou le fractionnement de flux, d’une part, et la spectrométrie de masse à plasma induit (ICP MS), d’autre part, présente un réel potentiel pour ces analyses. Ces approches sont détaillées d’une manière générale en termes de potentiels et de performances analytiques et des applications sont présentées pour différents éléments (As, Hg, Sn, Cr ou Sb).

Lignocellulose-based self-assembled micelles have emerged as a new generation of value-added functional nanostructures that show promise to address issues concerning the depletion of non-renewable resources; also these materials may contribute to the growing enthusiasm of utilizing biomass resources. Lignocellulose micelles can be conveniently prepared by self-assembly of amphiphilic lignocellulose derivatives in aqueous solution. They show great potential for applications in disparate fields, e.g. drug delivery, bioimaging diagnosis, sensing, nanoreacting, and so on. However, as a new research topic, a lot of research work would be needed to find out the critical structural factors that correlate with the formation, stability, morphology, and flexibility of lignocellulose micelles.

It is of merit to study the appropriate amount of dietary fiber to add to free-range chickens’ feed to improve their microbial diversity and gut health in times of plant fiber deprivation. Lignocellulose is a useful source of dietary fiber, and its positive effects on the growth performance and laying performance of chickens has already been proven. However, few researchers have researched the effects of adding it on the gut microbiota of chickens. In this research, we added three different levels of eubiotic lignocellulose (0%, 2%, and 4%) to the feed of caged and free-range Bian chickens from September to November, aiming to observe the effects of added dietary fiber and different rearing systems on the gut microbial diversity and gut health of chickens, as well as to determine an appropriate amount of lignocellulose. The results showed that adding dietary fiber increased the thickness of the cecum mucus layer and the abundance of Akkermansia and Faecalibacterium in caged chickens, and 4% lignocellulose was appropriate. In addition, adding lignocellulose increased the microbial diversity and the abundance of the butyrate-producing bacteria Faecalibacterium and Roseburia in fee-range chickens. The α-diversity and the length of the small intestine with 2% lignocellulose in free-range chickens were better than with 2% lignocellulose in caged chickens. Maybe it is necessary to add dietary fiber to the feed of free-range chickens when plant fibers are lacking, and 2% lignocellulose was found to be appropriate in this experiment. In addition, compared with caged chickens, the free-range chickens had a longer small intestine and a lower glucagon like peptide-1 (GLP-1) level. The significant difference of GLP-1 levels was mainly driven by energy rather than short chain fatty acids (SCFAs). There was no interaction between added dietary fiber and the rearing system on SCFAs, cecum inner mucus layer, and GLP-1.

Annotation:

Fungi are ecologically outstanding decomposers of lignocellulose. Fungal lignocellulose degradation is prominent in saprotrophic Ascomycota and Basidiomycota of the subkingdom Dikarya. Despite ascomycetes dominating the Dikarya inventory of aquatic environments, genome and transcriptome data relating to enzymes involved in lignocellulose decay remain limited to terrestrial representatives of these phyla. We sequenced the genome of an exclusively aquatic ascomycete (the aquatic hyphomycete Clavariopsis aquatica), documented the presence of genes for the modification of lignocellulose and its constituents, and compared differential gene expression between C. aquatica cultivated on lignocellulosic and sugar-rich substrates. We identified potential peroxidases, laccases, and cytochrome P450 monooxygenases, several of which were differentially expressed when experimentally grown on different substrates. Additionally, we found indications for the regulation of pathways for cellulose and hemicellulose degradation. Our results suggest that C. aquatica is able to modify lignin to some extent, detoxify aromatic lignin constituents, or both. Such characteristics would be expected to facilitate the use of carbohydrate components of lignocellulose as carbon and energy sources.

The study aims to investigate fungal community structures and dynamic changes in forest soil lignocellulose-degrading process. rRNA gene clone libraries for the samples collected in different stages of lignocellulose degradation process were constructed and analyzed. A total of 26 representative RFLP types were obtained from original soil clone library, including Mucoromycotina (29.5%), unclassified Zygomycetes (33.5%), Ascomycota (32.4%), and Basidiomycota (4.6%). When soil accumulated with natural lignocellulose, 16 RFLP types were identified from 8-day clone library, including Basidiomycota (62.5%), Ascomycota (36.1%), and Fungi incertae sedis (1.4%). After enrichment for 15 days, identified 11 RFLP types were placed in 3 fungal groups: Basidiomycota (86.9%), Ascomycota (11.5%), and Fungi incertae sedis (1.6%). The results showed richer, more diversity and abundance fungal groups in original forest soil. With the degradation of lignocellulose, fungal groups Mucoromycotina and Ascomycota decreased gradually, and wood-rotting fungi Basidiomycota increased and replaced the opportunist fungi to become predominant group. Most of the fungal clones identified in sample were related to the reported lignocellulose-decomposing strains. Understanding of the microbial community structure and dynamic change during natural lignocellulose-degrading process will provide us with an idea and a basis to construct available commercial lignocellulosic enzymes or microbial complex.

Annotation:

Lignocellulose is the most abundant renewable natural resource on earth and has been successfully used for the production of biofuels. A significant challenge is to develop cost-effective, environmentally friendly and efficient processes for the conversion of lignocellulose materials into suitable substrates for biotransformation. A number of approaches have been explored to convert lignocellulose into sugars, e.g. combining chemical pretreatment and enzymatic hydrolysis. In nature, there are organisms that can transform the complex lignocellulose efficiently, such as wood-degrading fungi (brown rot and white rot fungi), bacteria (e.g. Clostridium thermocellum), arthropods (e.g. termite) and certain animals (e.g. ruminant). Here, we highlight recent case studies of the natural degraders and the mechanisms involved, providing new utilities in biotechnology. The sugars produced from such biotransformations can be used in metabolic engineering and synthetic biology for the complete biosynthesis of natural medicine. The unique opportunities in using lignocellulose directly to produce natural drug molecules with either using mushroom and/or ‘industrial workhorse’ organisms (Escherichia coli and Saccharomyces cerevisiae) will be discussed.
