sp. nov., isolated from a freshwater green alga Free

Abstract

A Gram-stain-positive, facultatively aerobic and endospore-forming bacterium, designated strain Pch-40, was isolated from a freshwater green alga, . Cells were motile rods with a monotrichous polar flagellum showing catalase- and oxidase-positive reactions. Strain Pch-40 grew at 20–50 °C (optimum, 37–40 °C), at pH 5.0–11.0 (optimum, pH 7.0) and in the presence of 0–4.0 % (w/v) NaCl (optimum, 0 %). Menaquinone-7 was detected as the sole isoprenoid quinone. The genomic DNA G+C content of strain Pch-40 was 55.6 mol%. The major cellular fatty acids of strain Pch-40 were C, iso-C, anteiso-C and anteiso-C. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain Pch-40 clearly belonged to the genus of the family . Strain Pch-40 was most closely related to CSE-5610 with a 96.1 % 16S rRNA gene sequence similarity. The phenotypic and chemotaxonomic features and the phylogenetic inference clearly suggested that strain Pch-40 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is strain Pch-40 (=KACC 19279=JCM 32033).
