Summary
Brevibacterium sp. strain R312 has an endocellular β-glucosidase, a nitrile hydratase and an amidase that can break down some cyanoglucosides. Nonsterile cassava pulp suspensions were fermented using this strain and 70%–80% reduction of nitrile compounds, in particular cyanoglucosides and α-hydroxynitriles, was observed. This type of nitrile-hydratase-active microorganism could be a solution for the detoxification of cassava. Experiments conducted with the yeast Candida molischiana and C. wickkerhamii showed no improvement in detoxification.
