Screening and application of marine schizophyllum commune strain

Abstract

The invention provides a macro fungus, namely white ginseng, derived from coastal mudflat; the macro marine fungus is identified to be schizophyllum commune which is capable of growing in a high-salinity culture medium and is capable of generating schizophyllan. The marine schizophyllum commune disclosed by the invention is screened by virtue of a natural seawater prepared restrictive medium by taking rotten woods from coastal and seaside wetlands as samples; and the schizophyllum commune is subjected to liquid fermentation, so that the marine schizophyllan is obtained. The chemical component of the schizophyllan produced by the invention is beta-1,3 / 1,6-glucan, which is derived from the marine schizophyllum commune and is applicable to the fields of food, cosmetics and medicines; and the schizophyllan is suitable for industrial production and is quite high in application and popularization values.

Description

Technical field

[0001] The invention relates to the field of marine microorganisms and their natural products, in particular to the screening and cultivation of marine white ginseng fungi, the extraction and purification of schizophyllin produced, and the qualitative and quantitative analysis of schizophyllin. Background technique

[0002] Marine biological resources are due to the greater pressure of the water in the deep sea, lack of oxygen or even oxygen, continuous low temperature, occasional high temperature or cold springs, and the polar ocean environment is extremely extreme, cold, high salt and strong radiation. Marine organisms that survive and multiply in such an extreme marine environment must have a life system that adapts to the extreme living environment. Therefore, extreme environmental marine organisms are not only unique in species, but also contain many potential active substances and genetic resources, which have huge prospects for scientific research and comme...
