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 cold preservation slant cellulase enzymes, will grow in the secondary mycelium 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 in a test tube mixing aliquots cellulase textile, with 1kg / cm2 pressure sterilizer 30 minutes total of three times, to save a slant strain spore suspension was prepared as 1000ml Each sand tube into 0.5ml, shake, put inside filled with anhydrous CaCl2 vacuum dryer saved. It was determined that the measured 121 days, the enzyme activity is essentially the same; activity decreased by 50% of the time, be extended from 60 days to 160 days conventional methods cellulase powder, significantly slowed the rate of degradation of bacteria. 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. Share washing process - known as a sand blasting sandblasting (SPRAY STONE WASH / SAND BLAST) is a dedicated device (image point of speaking is a large electric toothbrush, but is drum type) polish on the cloth, There is usually a inflatable model fit.
