Valorization of rapeseed meal by solid state fermentation for an application in animal nutrition
2017
Solid state fermentation (SSF) is a biotechnological process particularly well adapted to the treatment of vegetable biomass. This technology adjustable to industrial scale, is adapted to current challenges in animal nutrition by developing fermented products in order to improve the quality of raw materials from a nutritional and functional point of view. The work presented in this thesis considers these issues using rapeseed meal from the oil crushing industry.A first screening study highlighted several fungal strains based on their growth performance and protein enrichment (total and digestible) of the substrate. Levels similar to those of soybean meal, the main protein source in animal n…

A simultaneous liquefaction, saccharification and fermentation (SLSF) process at very high gravity of cassava flour for potable ethanol production was developed at lab (1 L) and pilot scale (15 L and 1000 L). Cassava flour (CF) was mixed with tap water to obtain a concentration of 270 g/L dry matter. Sequentially, the mixture of a native starch hydrolyzing enzyme containing a mixture of alpha–amylase and gluco-amylase (Stargen 002 at 2565 GAU/kg CF), gluco-amylase (Amigase Mega L at 0.105% w/w), active dry yeast Saccharomyces cerevisiae (Red Ethanol at 3,5 × 10^7 cells/ml), KH2PO4 (9,9 mM) and urea (16.0 mM) was added into cassava slurry. The SLSF-VHG process including three steps of liquef…
Aroma production by solid state fermentation
2018
The adaptation of the production of γ-decalactones from submerged fermentation (SmF) to solid state fermentation (SSF) by Yarrowia lipolytica was investigated in this work. First of all, different solid matrices (corncob, cellulose sponge, luffa sponge, and castor seeds) were used for the first adaptation of the production of γ-décalactones. Luffa sponge appeared to be the most interesting solid support on which lactones were produced in higher concentrations than in the other solid matrices used. Then, the production of lactones using luffa sponge as the solid support was carried out in three types of SSF reactors to monitor different aeration conditions (without aeration, with a static ae…
