Texto completo da fonteTo bring value to by-products from the sugar industry and to contribute to a bio-refinery approach, the V2ARUN project revolves around the aconitic acid, which is the major organic acid in sugarcane. This thesis aims to produce aconitic acid and/or to convert other organic acids present in the stillage through biological ways in order to combine bioremediation and bioconversion. The evolution of the growth of filamentous fungi in stillage has shown that particular strains of the Aspergillus family grow very well (30 gL-1 of biomass) leading to a reduction rate of COD around 50%. However, the complex composition of the stillage, especially in polyphenols, prevents some strains of fungi to grow. For this reason, the screening of strains that can enhance the vinasse has been extended to a two step fungal culture: a preliminary culture in a malt medium followed by the transfer of the biomass produced in the stillage. This process promotes the development of more micro-organisms in stillage and allows to increase the physico-chemical quality of the stillage that which obtained in conventional batch cultivation. Thereafter, the fermented musts obtained are analysed for the purpose of studying the evolution of organic acids and especially the aconitic acid. The results indicate that micro-organisms consume organic acids to grow and no organic acid is produced by this method. Even though, this technique does not respond to the industrial requirements of the V2ARUN project, other metabolites such as lignocellulosic enzymes have been identified and have thus allowed to consider new applications

Texto completo da fonteThe pepsin hydrolysis of purified bovine hemoglobin or from a co-product of slaughterhouses: cruor, can be considered as an important route for obtaining antibacterial peptides. A kinetic study has allowed us to control the hydrolysis and to determine a mathematical model able to predict the concentration of each antibacterial peptides of two families of peptides α 1-32 and α 107-141 and those of an interval of temperature 15-37°C, of pH 3,5-5,5 and ratio enzyme/substrate of 1/5-1/20 . The calculation of activation energies for the different reactions involved in the mechanism was made by the Arrhenius equation, which was used to study the effect of temperature on the various kinetic coefficients. The effect of pH and ratio E / S was also studied and the model found showed a linear increase in the rate of hydrolysis decreasing the pH ( between 3,5 and 5,5 ) and an invariable speed with the ratio E / S ( 1/5-1/20 ). The study of the structure-function relationship of antibacterial peptides α 1-32 and α 137-141 was carried out thanks to a followed the kinetics of extracellular K + in the presence of Lisrea innocua and the minimal determinant antibacterial was determined for the peptide α 137-141. The possibility to recovery the antibacterial peptides α 1-32 and α 137-141 in to a bioactive food packaging against the growth of pathogenic bacteria has been studied by the adsorption of these peptides on the surface of a low density polyethylene film treated with cold plasma

Texto completo da fonteThe brewing industry has the potential to play a major role in the development of a sustainable bioeconomy by becoming a biorefinery. A brewing byproduct has the potential to replace antioxidant additives in various industries such as food and cosmetics, as it contains high levels of phenolic compounds. In collaboration with a brewery company, researches were conducted to valorizebiomolecules and reuse chemicals and water. Physico-chemical and phenolic composition of the byproduct was characterized. Bio-based phenolic compounds were recovered with (i) ultrafiltration membrane selection for the wastewater clarification, (ii) optimization of coupled ultra-nanofiltration clarification/concentration process with selectivity and fouling mechanisms investigation, (iii) exploration of alternative recovery processes such as resin adsorption, and (iv) performance of a business case study in order to assess economic performances of designed process in an industrial scale

Texto completo da fonteThe increase of energy demand and the limitation of oil resources explain the need to find a new alternative to fossil fuels. The chemical composition and energy content of fish by-products offer the potential to transform them into biodiesel. The main objective of this thesis is the valorization of these by-products into biofuel by using the reactive extrusion process. For this purpose, three types of fishby-products (salmon, trout and sardine) were investigated by using the reactive extrusion process.To realize this objective, three types of fish coproducts (salmon, trout and sardine) were valorized by enzymatic hydrolysis in reactive extrusion. The experimental study allowed to optimize the process and to highlight the gains made compared to the batch process: oil extraction efficiency, time and reagent savings. The oil phases extracted from the abovementioned process were analyzed to choosethe oil that represents properties similar to biodiesel. The study of fatty acid profiling and triglyceride contents in the three types of oil has shown that salmon oil is the most suitable oil for biodiesel production. The parameters of the transesterification reaction of salmon oil to biodiesel have been optimized. The characterization of biodiesel produced from this oil has properties similar to those of conventional diesel in accordance with European EN14214 and American ASTM D6751 standards

Texto completo da fonteThis work consists of the valorization of citrus by-products with innovative technologies. Citrus pressing produces millions of tons of waste per year worldwide. This waste (peels, pulps and seeds) is generally dedicated to animal feed or eliminated by composting or incineration. However its content in bioactive molecules leads to several ways of valorization. Since peels present about half of the citrus waste mass, studies have been focused on the valorization of citrus peels by the extraction of bioactive compounds. Conventional methods generally used for the extraction of bioactive compounds (solid-liquid extraction, hydrodistillation) have several disadvantages such as the use of expensive and toxic solvents, long extraction times and high energy consumption. For this reason, several innovative non-thermal technologies such as Pulsed Electric Fields (PEF), High Voltage Electrical Discharges (HVED) and Ultrasounds (US) and thermal treatments such as microwaves (MO) and infrared (IR) have been tested for the valorization of citrus by-products. Whole citrus fruits (oranges, pomelos, lemons) were PEF treated at an intensity of 3 kV/cm, then citrus juice and polyphenols were extracted by pressing. The study of the PEF-induced cell permeabilization was conducted by several methods and showed that the degree of damage varied according to the type of the treated fruit. The electroporation of the cells induced by the PEF, allowed an increase the juice yields after pressing and improved the liberation of the polyphenols from the citrus peels into the juice. This explains the possibility of obtaining a juice rich in polyphenols by treating the whole fruits with PEF before pressing. Among the solvents tested for the extraction of polyphenols from citrus peels, water is the least effective. The addition of 20% glycerol to water changed the polarity of the medium and improved the extraction of the polyphenols. The use of an enzyme mixture enhanced the release of the polyphenols related to the polysaccharides. Deep eutectic solvents have been as effective as hydroethanolic mixtures. To improve the yields and the kinetics of extractions in the different green solvents and in the enzyme mixture, citrus peels were pretreated with HVED in water. The mechanical effect of HVED, based on the fragmentation of the peels has improved the extraction of polyphenols in the various solvents. The intensification of polyphenols extraction was also conducted by IR and US. The extraction of polyphenols by IR was optimized using the surface response methodology. IR heating did not alter the extracted polyphenols which have significant antifungal and anti-mycotoxinogenic activities. The pretreatment of citrus peels with IR weakened the cell structures, increasing thus the diffusion of polyphenols during US treatment

Texto completo da fonteThe elimination of seashell by-products is an important issue for coastal regions of France. Among many possibilities, valorization of these wastes as aggregates for concrete is a solution that deserves to be evaluated. This study focuses on the behavior of pervious concrete based seashell by-products (slipper limpets, scallops and queen scallops). A partial substitution (20, 40 and 60% by mass) of natural gravel was carried. The results show unequivocally that the presence of these crushed shells is detrimental for mechanical and hydraulic behaviors and durability of concrete and the strength decreases with the increasing substitution rate and with the order of nature shells: slipper limpets, scallops then queen scallops. The experimental results showed that the seashells by-products can be used to design pervious concrete that meet the criteria of mechanical strength and water permeability. The incorporation of seashell by-products in pervious concrete is a solution to managing waste shells produced by fishing and shellfish farming industries and a contribution to environmental protection
