This study is aimed at developing a two-step process (fermentation plus enzymatic hydrolysis) for protease and peptone production, using a bioethanol industry by-product – corn distiller's dried grains with solubles (CDDGS) – as the sole carbon/nitrogen and protein source, respectively.Bacillus licheniformis was used for protease production. CDDGS concentration is the main parameter controlling protease...
Lactic acid production by batch-fed fermentation of deproteinized whey, using immobilized cells of Lactobacillus pentosus-4023 in a spirally wound fibrous-sheet packed-column reactor, has been investigated. This fermentation process has been studied to produce low-cost lactic acid 'in situ' and to investigate its direct use for the demineralization of crayfish chitinous fraction (exoskeleton). Chitin...
