  • Bacterial strain THMBR28 was isolated from decomposing algal scum that was collected during an algal bloom in Taihu lake, China. Cells of strain THMBR28 were Gram-staining-positive, facultatively anaerobic and rod-shaped. Growth was observed at 20–45 °C (optimum, 30 °C), at pH 5.0–9.5 (optimum, pH 6.5–7.5), and in the presence of 0–1.0  % (w/v) NaCl (optimum, 0.5  %). Strain THMBR28 contained MK-7 as the major menaquinone and iso-C as the major cellular fatty acid. The polar lipid profile contained phosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidylethanolamine and six unidentified polar lipids. The diamino acid found in the cell-wall peptidoglycan was diaminopimelic acid. The DNA G+C content was 57.6 mol% ( ). Phylogenetic analysis of 16S rRNA gene sequences showed that strain THMBR28 belonged to the genus , most closely related to DSM 18389 (95.0  %) and Eur1 9.5 (93.4  %). Based on phylogenetic and phenotypic characterization, it is concluded that strain THMBR28 represents a novel species of the genus , for which the name sp. nov. is proposed, with THMBR28 ( = CGMCC 1.10949 = NBRC 108765) as the type strain.

  • The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain THMBR28 is JX110710.

  • Two supplementary figures are available with the online Supplementary Material.
