Abstract

A novel Gram-stain-positive, rod shaped and anaerobic bacterium, designated as W6, was isolated from Shengli oilfield in China. Strain W6 was observed to grow from 20 to 45 °C with pH 6.5–9.0 (optimally at 40 °C and pH of 7.5) and without addition of NaCl. The major cellular fatty acids were iso-C (29.1%), C (27.0%) and C (12.2%), and the main polar lipids were lipids (L) and aminolipids (AL). The DNA G+C content is 42.9 mol%. Based on 16S rRNA gene sequence analysis, strain W6 showed highest similarities to DSM 9508 (94.9%) and DSM 12858 (94.1%). The morphological, physiological, biochemical, phylogenetic and phylogenomic analyses demonstrated strain W6 (CCAM 534=DSM 28124=CGMCC 1.5291) represents a novel species in a new genus for which the name gen. nov. sp. nov. is proposed. The family is proposed as a new family containing the genera , , , , , , , and species based on the phylogenetic and phylogenomic analyses.
