Lishizhenia caseinilytica gen. nov., sp. nov., a marine bacterium of the phylum Bacteroidetes

Int J Syst Evol Microbiol. 2006 Oct;56(Pt 10):2317-2322. doi: 10.1099/ijs.0.64415-0.

Abstract

A light-orange, aerobic bacterium, strain UST040201-001(T), that degrades casein, gelatin and Tween 20, was isolated in February 2004 from a sand-filtered seawater sample from Port Shelter, Hong Kong SAR, China. The strain possessed menaquinone-6 and its 16S rRNA gene sequence shared only 90.1 % similarity with that of Brumimicrobium glaciale IC156(T). Phylogenetic analysis showed that UST040201-001(T) formed a distinct lineage within the family Cryomorphaceae. Its ecophysiological and biochemical characteristics suggest that this strain represents a novel genus and species within the phylum Bacteroidetes. The name Lishizhenia caseinilytica gen. nov., sp. nov. is proposed. The type strain of Lishizhenia caseinilytica is UST040201-001(T) (=NRRL B-41434(T)=JCM 13821(T)).
