Watanabe, Tomohiro Yabe, Tatsuya Tsuji, Jackson M Fukui, Manabu Phylogeny RNA, Ribosomal, 16S Lakes Geologic Sediments DNA, Bacterial Sulfates Bacterial Typing Techniques Base Composition Sequence Analysis, DNA Japan Genome, Bacterial Glucose Oxidation-Reduction A novel sulphate-reducing bacterium, strain 52FAK, was isolated from a sediment sample collected from a brackish lake, Lake Akkeshi, Japan. Growth occurred at 15-30 °C (optimum 22-25 °C), pH 6.9-8.2 (optimum 7.1-7.3) and 50-700 mM sodium chloride (optimum 150-300 mM). Strain 52FAK utilized hydrogen ga, various organic acids and alcohols as electron donors. Sulphate, sulphite, thiosulphate and nitrate served as electron acceptors. A distinctive feature is its ability to grow on glucose. The 52FAK genome consists of a circular chromosome with a length of 5.6 Mb and a G+C content of 43.6 mol%. The genome encodes a putative glucose-specific phosphotransferase system, which is likely involved in glucose uptake. Phylogenetic analyses placed strain 52FAKᵀ within the genus , with 16S rRNA sequence identities of 96.3% with and 94.1% with . Based on phylogenetic and phenotypic properties, strain 52FAKᵀ is proposed as a new species, sp. nov., with the type strain 52FAKᵀ (=JCM 39400=DSM 113749). |
