Chitiniphilus shinanonensis gen. nov., sp. nov., a novel chitin-degrading bacterium belonging to Betaproteobacteria.

Abstract

A bacterial strain capable of degrading chitin, strain SAY3T, was isolated from moat water of Ueda Castle in Nagano Prefecture, Japan. The strain was gram-negative, curved rod-shaped, facultatively anaerobic, and motile with a single polar flagellum. It grew well with chitin as a sole carbon source. The cellular fatty acids profiles showed the presence of C16:1 omega7c and C16:0 as the major components. The G+C content of DNA was 67.6 mol% and Q-8 was the major respiratory quinone. A 16S rRNA gene sequence-based phylogenetic analysis showed the strain belonged to the family Neisseriaceae but was distantly related (94% identity) to any previously known species. Since the strain was clearly distinct from closely related genera in phenotypic and chemotaxonomic characteristics, it should be classified under a new genus and a new species. We propose the name Chitiniphilus shinanonensis gen. nov., sp. nov. The type strain is SAY3T (=NBRC 104970T=NICMB 14509T).
