The use of cellulases for increasing the sugar content of AIV-silage

The use of cellulases for increasing the sugar content of AIV-silage

AIV silages were treated with cellulases. Five different enzyme preparations were compared. The highest amount of reducing sugar in silage was 190 g/kg (dry basis) and the highest amount of glucose in the press juice 24 g/dm3. A combination of two enzyme preparations produced more glucose than any e...

A combination of two enzyme preparations produced more glucose than any enzyme tested alone. Glucose production was approximately proportional to the enzyme concentration. Because of lactic acid fermentation, cellulase alone could not maintain the sugar content at a high level, a preservative being required to inhibit the lactic acid bacteria.
