Embodiment 1

[0049] 1. Preservation of Streptomyces cyprinis

[0050] The Streptomyces carpii of the present invention is isolated from Zhanjiang mud samples in Guangdong, which is a marine microorganism and a Gram-positive bacterium. The basal filaments were gray and the air filaments were gray when cultured on Gaoshi No. 1 synthetic medium.

[0051]The 16S rDNA gene sequence number of the strain is KC832293.1 (the gene number is GI:483124984), and the strain is identified as Streptomyces cyprinis by morphological characteristics and 16S rDNA sequence Streptomyces carpaticus OUCMDZ-726. The strain was deposited in the General Microorganism Center (CGMCC) of China Committee for Microbial Culture Collection on April 11, 2013; address: No. 3, Yard 1, Beichen West Road, Chaoyang District, Beijing, Institute of Microbiology, Chinese Academy of Sciences; date of preservation: April 11, 2013; Streptomyces carpii Streptomyces carpaticus Deposit number: CGMCC No. 7461.

Abstract

The invention discloses a Streptomyces-carpaticus-derived marine microbial polysaccharide and a preparation method thereof. According to the invention, the marine-derived Streptomyces carpaticus OUCMDZ-726 is fermented to prepare the marine microbial polysaccharide in novel chemical structure, which is a linear homopolymer formed by connecting 3-desoxy-D-glycerol-D-ganonulose with alpha-2,8. The marine microbial polysaccharide has unique structure, is derived from marine microbes, can be used for producing and researching precursors or intermediates of novel drugs, and thus, can be fully utilized; and the functions and activities of the marine microbial polysaccharide can be widely developed.

Description

technical field [0001] The invention belongs to the field of marine microorganisms, and in particular relates to a marine microbial polysaccharide derived from Streptomyces carpii and a preparation method thereof. Background technique [0002] The ocean contains rich microbial resources. Due to the special living environment, the synthesis process of marine microorganisms is different from that of terrestrial microorganisms, and many active polysaccharides with novel structures and special functions are produced. Research on exopolysaccharides of marine microorganisms has attracted increasing attention. Many novel polysaccharides have been isolated from general environmental marine microorganisms, marine symbiotic microorganisms, and marine special environmental microorganisms. Studies have shown that most of these polysaccharides are heteropolysaccharides composed of various monosaccharides in a certain proportion and connection mode. The composition of monosaccharides inv...
