RT Journal Article SR Electronic(1) A1 Lee, Yunho A1 Jeon, Che OkYR 2017 T1 Cohnella algarum sp. nov., isolated from a freshwater green alga Paulinella chromatophora JF International Journal of Systematic and Evolutionary Microbiology, VO 67 IS 11 SP 4767 OP 4772 DO https://doi.org/10.1099/ijsem.0.002377 PB Microbiology Society, SN 1466-5034, AB A Gram-stain-positive, facultatively aerobic and endospore-forming bacterium, designated strain Pch-40T, was isolated from a freshwater green alga, Paulinella chromatophora. Cells were motile rods with a monotrichous polar flagellum showing catalase- and oxidase-positive reactions. Strain Pch-40T 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-40T was 55.6 mol%. The major cellular fatty acids of strain Pch-40T were C16 : 0, iso-C16 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain Pch-40T clearly belonged to the genus Cohnella of the family Paenibacillaceae . Strain Pch-40T was most closely related to Cohnella rhizosphaerae CSE-5610T with a 96.1 % 16S rRNA gene sequence similarity. The phenotypic and chemotaxonomic features and the phylogenetic inference clearly suggested that strain Pch-40T represents a novel species of the genus Cohnella , for which the name Cohnella algarum sp. nov. is proposed. The type strain is strain Pch-40T (=KACC 19279T=JCM 32033T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002377
