| Abstract |
Strain ZH6T is a Gram-stain-negative, rod-shaped, aerobic bacterium isolated from manganese mine soil. Strain ZH6T had highest 16S rRNA gene sequence similarities to Mucilaginibacter yixingensis YX-36T (96.9 %) and Mucilaginibacter psychrotolerans NH7-4T (96.8 %). The genome size of strain ZH6T was 4.61 Mb with a DNA G+C content of 44.0 mol%. The average nucleotide identity and digital DNA-DNA hybridization values between strain ZH6T and M. yixingensis DSM 26809T were 70.6 and 19.2 %, respectively. Strain ZH6T had menaquinone-7 as a major quinone and main cellular fatty acids of iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c). The polar lipids of strain ZH6T were a phosphatidylethanolamine, an unidentified glycolipid, an unidentified phospholipid, three unidentified aminophospholipids and four unidentified lipids. Based on the phenotypic, chemotaxonomic and phylogenetic results, strain ZH6T represents a novel species of the genus Mucilaginibacter, for which the name Mucilaginibacterterrenus sp. nov., is proposed. The type strain is ZH6T (=CCTCC AB 2018373T=KCTC 72075T).
