Pulps derived from oat husks by the combined method (prehydrolysis, alkaline delignification, treatment with nitric acid solution) are shown to posses high reactivity towards fermentation upon hydrolysis with the mixed enzyme preparations BrewZyme BGX and CelloLux-A. The dependence of the increment in reducers on the original concentration of the substrate in the range of 15 to 120 g/L is studied, and the linear decrease in the final yield of reducers (in 72 h) ranging from 98 to 73% with increasing original substrate concentration is revealed.
