Cellulase enzymes in the food industry and environmental industries are widely used. During alcoholic fermentation, cellulase added raw material utilization efficiency can be increased cellulase, and wine quality has improved. Since the purified cellulase difficult, practical applications usually contain hemicellulose and other related enzymes, such as amylase (amylase), protease (Protease) and the like. Cellulase wide range of sources is very broad. Different sources of cellulase its structure and function vary greatly. Guangzhou Long Li Biotechnology Limited mainly engaged in biological enzyme and textile auxiliaries, the main products are: Acid cellulase, neutral cellulase, the original enzyme, laccase, desizing enzymes, oxygen enzyme; anti-pollution pink anti-agent, enzyme water special anti-agent, anti-pollution soap oil, NP8.6, brighteners. Cellulase bacteria easily degraded after enzymatic degradation of its production force decreased, the reason may have three aspects: ① by mutagenesis screening revertant strains occur. ② natural negative mutation. ③ strains prolonged hypothermia slant preservation, will grow secondary mycelium cellulase textile on conidia, hyphae and conidia formed secondary vitality weak, this may be the main reason for degradation of species. In order to avoid degradation of cellulase bacteria, Zhang Ling, flowers, etc. (1998) reported that the use of sand deposited strains tube. Upcoming sieved washed sand and soil with 3: 2 ratio of mixing dispensed in a test tube, with 1kg / cm2 pressure sterilizer 30 minutes total of three times, to save a slant strain 1000ml prepared spore suspension, each sand 0.5ml tube into the soil cellulase, shake, put inside filled with anhydrous CaCl2 vacuum dryer saved. It was determined that, measured in 121 days, the enzyme activity is essentially the same; activity decreased by 50% of the time Buy cellulase, extended from 60 days to 160 days of conventional methods, significantly slowed the rate of degradation of bacteria.
