The ability of a charged UF membrane to fractionate the small peptides found in a rapeseed protein enzymatic hydrolysate, according to their charge characteristics, was investigated. The complexity of such a hydrolysate has required the setting up of technological alternatives to isolate the small
Rapeseed meal (RSM) hydrolysate was evaluated as substitute for commercial nutrient supplements in 1,3-propanediol (PDO) fermentation using the strain Clostridium butyricum VPI 1718. RSM was enzymatically converted into a generic fermentation feedstock, enriched in amino acids, peptides and various
