Abstract

A polyphasic taxonomic approach was employed to characterize a strain designated GPTSA100-9, which was isolated from water sampled from a warm spring. The micro-organism, comprising Gram-negative, strictly aerobic rods, could not grow on nutritionally rich media such as tryptic soy broth. Analysis of the 16S rRNA gene sequence (1396 nt) of strain GPTSA100-9 revealed that it is a member of the genus , sharing 99.8 % sequence similarity with the CFB group bacterium strain A0653 (AF236016), 93.4 % with ‘[] subsp. ’ and 93.2–92.0 % with , , and . The G+C content of the genomic DNA was 31.0 mol%. The major fatty acids of the strain grown on modified R2A agar were iso-C (18.5 %), iso-C G (18.0 %), summed feature 3 (iso-C 2-OH and/or C 7, 16.6 %) and iso-C 3-OH (9.0 %). On the basis of phenotypic and genotypic characteristics, strain GPTSA100-9 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is GPTSA100-9 (=MTCC 6936=DSM 17447).
