| Summary: | Enzymatic stability is undoubtedly one of the most important factors in biotechnology. In this sense, the stability of cellulases present in crude extracts of submerged cultures of Bacillus sp. SMIA-2 during freezing at 3 °C and in the presence of additives was studied. Cellulases were stable during storage for 154 days at 3 °C. The activity of avicellase and CMCase was maintained when crude extracts containing the enzymes were incubated in the presence of ethylene glycol (1M), glycerol (1%) and polyethylene glycol (0.01M) for 1 hour at room temperature. |
