This work describes batch anaerobic digestion tests carried out on stillages, the residue of the distillation process on fruit, in order to contribute to the setting of design parameters for a planned plant. The experimental apparatus was characterized by three reactors, each with a useful volume of 5 L. The different phases of the work carried out were: determining the basic components of the ...

BACKGROUND Thin stillage was used as the substrate to produce intracellular selenium-enriched polysaccharides (ISPS) from Cordyceps sinensis to increase the value of agricultural coproducts. METHODS Fermentation parameters were optimized using response surface methodology (RSM) to improve the production of ISPS. Then, the effects of ISPS on the antioxidant activities in vitro, as well as the ...
