Collagenase-producing bacteria and their collagenases play important roles in collagen degradation and organic nitrogen recycling in the ocean. However, only a few collagenase-producing marine bacteria have been so far discovered. Here, we reported the isolation and characterization of a collagenase-secreting bacterium, designated strain SM1988^T, isolated from a green alga <i>Codium fragile</i> sample. Strain SM1988^T is a Gram-negative, aerobic, oxidase-, and catalase-positive, unipolar flagellated, and rod-shaped bacterium capable of hydrolyzing casein, gelatin and collagens. Phylogenetic analysis revealed that strain SM1988^T formed a distinct phylogenetic lineage along wiFrontiers in microbiology621161https://www.ebi.ac.uk/biostudies/studies/S-EPMC8005334biostudies-literatureTaxonomic and Enzymatic Characterization of <i>Flocculibacter collagenilyticus</i> gen. nov., sp. nov., a Novel Gammaproteobacterium With High Collagenase Production.PMC8005334Song XYZhang YZZhang XYSun ZZHe XYLi JWang PShi MTeng ZJTian XCheng JHChen XLfalseTaxonomic and Enzymatic Characterization of <i>Flocculibacter collagenilyticus</i> gen. nov., sp. nov., a Novel Gammaproteobacterium With High Collagenase Production.Collagens from marine animals are an important component of marine organic nitrogen.
