Abstract

A strictly anaerobic bacterial strain, designated Jerry-YX, was isolated from petroleum-contaminated soil sampled in China. Strain Jerry-YX was a Gram-stain-negative bacterium forming reddish colonies. It grew optimally at 30 °C and pH 7.0, and tolerated 1.0 % (w/v) NaCl. Strain Jerry-YX was able to use fumarate, ferric citrate and ferrihydrite as electron acceptors, and ethanol, acetate and benzoate as electron donors. The major fatty acids of this strain were C and C 7/C 6 (summed feature 3). The 16S rRNA gene sequence-based phylogenetic analysis placed this strain in the genus , being most closely related to (98.2 % similarity), (98.1 %) and (98.0 %). The DNA G+C content was 57.6 mol%. The average nucleotide identity and digital DNA–DNA hybridization values between the genomes of strain Jerry-YX and GS-15 were 81.8 and 35.4 %, respectively. The results of the polyphasic study allowed the genotypic and phenotypic differentiation of strain Jerry-YX from its closest species, which suggested that strain Jerry-YX represents a novel species of the genus . The name for the proposed new species is sp. nov. The type strain is Jerry-YX (=MCCC 1K05659=JCM 39190).
