Patent ID: 10612008

Abstract:
The present invention discloses a Streptomyces sp. strain and a method for preparing a sulfide oxidase preparation from the same. This strain is a Streptomyces sp. strain DS021-Z5D2 which is a mutant having a high yield of sulfide oxidase obtained by taking a Streptomyces sp. strain DS021 as a starting strain and performing strain mutation by means of compound mutation of ultraviolet light and diethyl sulfate, and the preservation number is CGMCC No. 12808. This strain has the advantages of quick growth speed, high enzymatic productivity and the like. When this strain is fermented by a high-density fermentation method, this strain can produce sulfide oxidase preparations at a high yield. This strain has the advantages of inexpensive and easily-available culture substrates, high enzymatic productivity, short fermentation period, low production and use cost, and the like.
