Abstract
The stability of neutral β-mannanase from Bacillus licheniformis during operation and storage was investigated. The enzyme activity decreased by 70% with a hydrolysate of glucomannan at 20 g l−1 over 30 min at 25 °C. In an enzymatic membrane reactor operated at 50 °C after 24 h, the loss of enzyme activities were 23% and 9% in the absence/presence of the substrate. The residual activities of the enzyme were 21% and 90%, respectively, when stored in 30% (v/v) glycerol solution and in solid state at 4 °C after one year.
