Based on the growth characteristics of the bacterium at 35-55 degrees C and pH 4.0-6.0, as well as the 16S rRNA gene sequence similarity and whole genome analyses, strain skT53(T) was identified as a novel species Effusibacillus dendaii sp. nov.
A Gram-positive, rod-shaped, spore-forming, thermophilic, and acidophilic bacterium, designated as strain skT53(T), was isolated from farm soil in Tokyo, Japan. Under aerobic conditions, the strain grew at 35-55 degrees C (optimum temperature 44-55 degrees C) and pH 4.0-6.0 (optimum pH 5.0). Phylogenetic analysis of the 16S rRNA gene sequence showed that the isolate was moderately related to the type strain of Effusibacillus consociatus (94.3% similarity). The G + C content of the genomic DNA was 48.2 mol%, and MK-7 was the predominant respiratory quinone in the strain. The major fatty acids were anteiso-C-15:0, iso-C-15:0, and iso-C-16:0. Based on the phenotypic and chemotaxonomic characteristics, as well as 16S rRNA gene sequence similarity and whole genome analyses, strain skT53(T) represents a novel species in the genus Effusibacillus, for which the name Effusibacillus dendaii sp. nov. has been proposed. The type strain is skT53(T) (= NBRC 114101( T) = TBRC 11241( T)).
