Cells of strain LAM0A37T were rod-shaped and motile by peritrichous flagella. The optimal temperature and pH for growth were 40 °C and 7.0–7.5, respectively. The strain did not require NaCl for growth but tolerated up to 3 % (w/v) NaCl. Strain LAM0A37T was able to utilize glucose, fructose, maltose, xylose, sorbitol, cellobiose, melibiose and melezitose as sole carbon sources. Sulfite was used as an electron acceptor. The main products of glucose fermentation were acetate and CO2. The predominant fatty acid was C16 : 0 (23.6 %). The main polar lipid profile comprised of five glycolipids, six phospholipids and two lipids. No menaquinone was detected. The genomic DNA G+C content was 27.1 ± 0.2 mol% as determined by the T m method. Analysis of the 16S rRNA gene sequence indicated that the isolate was a member of the genus Terrisporobacter, and was most closely related to Terrisporobacter glycolicus JCM 1401T and Terrisporobacter mayombei DSM 6539T with 98.3 % 16S rRNA gene sequence similarity to both. DNA–DNA hybridization values between strain LAM0A37T and type strains of Terrisporobacter glycolicus and Terrisporobacter mayombei were 45.6 ± 0.3 % and 38.3 ± 0.4 %, respectively. Based on phenotypic, phylogenetic and chemotaxonomic characteristics, strain LAM0A37T is suggested to represent a novel species of the genus Terrisporobacter, for which the name Terrisporobacter petrolearius sp. nov. is proposed. The type strain is LAM0A37T ( = ACCC 00740T = JCM 19845T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.000450
