Abstract

A novel bacterial strain, designated ZL, isolated from a warm spring in Jhonglun, Taiwan, was characterized by using a polyphasic taxonomic approach. The novel strain had chemotaxonomic and morphological properties consistent with its classification in the genus . Cells were Gram-variable, aerobic, sporulating, motile rods. 16S rRNA gene sequence analysis demonstrated that this novel isolate was unique, showing 94.3 % sequence similarity to GPTSA 11 and lower levels to 2301032 (94.0 %), ATCC 8244 (93.3 %), SAFN-016 (93.3 %) and 2301083 (93.2 %). The novel isolate could be distinguished from the type strains of all of these species based on a range of phenotypic data. The major cellular phospholipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and one unknown phosphoglycolipid. The predominant isoprenologue was an unsaturated menaquinone with seven isoprene units (MK-7). The major fatty acids of strain ZL were C (33.5 %), anteiso-C (32.5 %) and iso-C (9.3 %). The G+C content of the genomic DNA was 49.2 mol%. It is evident from the genotypic and phenotypic data that strain ZL should be classified as representing a novel species of the genus , for which the name sp. nov. is proposed. The type strain is ZL (=BCRC 17579=LMG 23577).
