Abstract

A motile, Gram-negative, rod-shaped bacterium, designated strain JS11-7(T), was isolated from forest soil from Halla Mountain, Jeju Island, Korea. It grew optimally at 28 degrees C, pH 6-7 and in the presence of 0-2 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain JS11-7(T) belongs to the family Neisseriaceae, with Silvimonas terrae as its closest relative (95.0 % similarity). It contained Q-8 as the predominant quinone and summed feature 3 (comprising iso-C(15 : 0) 2-OH and/or C(16 : 1) omega 6c), C(16 : 0) and C(18 : 1) omega 7c as the major fatty acids. The DNA G+C content was 62 mol%. On the basis of phenotypic and genotypic characteristics and the results of 16S rRNA gene sequence analysis, strain JS11-7(T) represents a novel genus and species, for which the name Andreprevotia chitinilytica gen. nov., sp. nov. is proposed. The type species is Andreprevotia chitinilytica and the type strain is JS11-7(T) (=KACC 11608(T)=DSM 18519(T)).
