[Microbiological degradation of glucosinolates in defatted rapeseed meal].
During the degradation of thioglucosides in defatted rape seed meal (RES) microorganisms were found, whose ability to degrade glucosinolates (GSL) and vinyl thio-oxazolidone (VTO) was not known so far. The isolated microorganisms are two strains of bacteria of the species Bacillus cereus and the yeast Trichosporon cutaneum. The degradation of GSL and VTO in the cultural broths by the Bacillus cereus strains was the more complete the more other Gram-negative bacteria from RES were additionally present. Drinking tests with Wistar rats showed that here is a relation between the watersoluble and mainly bitter toxin substances of rape and their influence on the increase of the animals body weight.
