sp. nov., isolated from decomposing algal scum Free

Abstract

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.
