METHOD OF SERRATIA MARCESCENS CULTURAL FLUID PREPARATION SHOWING CHITINASE ACTIVITY

摘要

The use of biotechnology, process for the preparation of culture liquid Serratia mercescens with chitinase activity. Chitinase (KF 3. 2.1.4) may be used for bioconversion chi-tinsoderzhaschih waste protein unicellular yeast, insect and pathogenic fungi, pests of agricultural plants such as a biochemical reagent in laboratory practice. SUMMARY OF THE INVENTION: an act of culturing a mutant Serratia marcescens strain VKPM B-4870 on medium containing in g / l: ammonium citrate, 5.0; glycerin 5.0; K2NRO "10.0; MgS04 «7H20 0.5; NaCI 0,5; FeO / jO, 025; corn steep liquor, 2.5; pH 7.6 for 24 h at 30 & amp; deg; C with aeration.
