Thermomonas carbonis sp. nov., isolated from the soil of a coal mine.

Strain GZ436(T) was Gram-stain-negative, aerobic, non-motile, rod-shaped and isolated from the soil of a coal mine. 16S rRNA gene phylogenetic analysis showed that this strain clustered with Thermomonas brevis LMG 21746(T) (97.5%), Thermomonas haemolytica A50-7-3(T) (96.3%), Thermomonas koreensis KCTC 12540(T) (96.4%), Thermomonas hydrothermalis SGM-6(T) (95.5%) and Thermomonas fusca LMG 21737(T) (95.1%). The major isoprenoid quinone was Q-8. The DNA G+C content was 67 mol%. Strain GZ436(T) contained phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, an unknown aminophospholipid, an unknown phospholipid and an unknown lipid as the major polar lipids. The predominant cellular fatty acids (>5%) were iso-C(15:0), iso-C(11:0), iso-C(11:0 3)-OH, iso-C(17:1)ω9c, C(16 : 0) and summed feature 3. The DNA-DNA relatedness value between strain GZ436(T) and T. brevis LMG 21746(T) was 54 ± 0.4%. According to phenotypic and phylogenetic characteristics, strain GZ436(T) represents a novel species of the genus Thermomonas, for which the name Thermomonas carbonis sp. nov. is proposed. The type strain is GZ436(T) ( =CCTCC AB 2013364(T) = KCTC 42013(T)).
