On July 1 , the international academic journal Environmental Microbiology published an article titled " Maribellus comscasis sp.
Seaweed polysaccharides (cellulose, pectin, fucoidan, etc.
To this end, Sun Chaomin’s research group used deep-sea cold spring samples collected by the scientific research ship "Science" in 2018 to analyze the high abundance of Bacteroides and the characteristics of algae polysaccharide degradation genes by metagenomic methods; and then based on Bacteroides degrading polysaccharides.
The researchers speculated based on the research results that the easily degradable algae polysaccharides are first used by microorganisms on the ocean surface, while the hard-to-degrade polysaccharides aggregate to form granular debris and sink into the deep sea
Dr.
Based on the degradation characteristics of polysaccharides, a strain of Bacteroides deepsea that can significantly degrade various algae polysaccharides was purely cultivated
Transcriptome and Metabolome Joint Analysis of Molecular Mechanisms of Degradation and Utilization of Cellulose by Deep-sea Bacteroides
