AI Technical Summary

Technical Problem

Under the low temperature and saline-alkali conditions in the Northeast region, the biodegradation rate of cellulosic agricultural waste is slow. The cellulase activity of existing strains is inhibited in this environment, making it difficult to effectively degrade cellulose.

Method used

Provided is a low-temperature, salt-alkali-tolerant Streptomyces microflavus CLSD-1, which grows well under conditions of 10-30°C and 0-3.0% salinity, has high cellulase activity, and can rapidly degrade cellulose through fermentation culture.

Benefits of technology

It can quickly degrade cellulose in low-temperature saline-alkali environments, improve cellulase activity, and achieve efficient cellulose degradation rate, which is suitable for the utilization of cellulose resources in low-temperature saline-alkali areas.

Abstract

The invention discloses low-temperature salt-tolerant and alkali-tolerant streptomyces microflavus and application thereof, relates to the technical field of microorganisms, and is characterized in that the preservation number of the streptomyces microflavus is CCTCC (China Center for Type Culture Collection) M2023664. The streptomyces microflavus provided by the invention can well grow at the temperature of 10-30 DEG C. In a Congo red decoloration test, the ratio of the diameter (D) of a transparent circle to the diameter (d) of a bacterial colony is 3.6. The strain is applied to degradation of cellulose, has the advantages of degradation of cellulose at low temperature, high cellulase activity, salt resistance, alkali resistance and the like, and can be particularly used for cellulose degradation strain resources in low-temperature saline-alkali areas.
