sp. nov., isolated from waste water Free

Abstract

A Gram-stain-negative, non-spore-forming, rod-shaped, non-motile bacterium, named wh15, was isolated from the waste water of a municipal wastewater treatment plant in Wuhu, PR China. The taxonomic status of the strain was characterized using a polyphasic taxonomic approach. Growth occurred at 15–45 °C (optimum, 25–40 °C), at pH 5.0–8.0 (optimum, pH 7.0) and with 0–4 % NaCl (optimum, 1–2 %). Phylogenetic analyses based on 16S rRNA gene sequences revealed that wh15 represented a member of genus and shared the highest similarity with DS-12 (93.93 %), 454–2 (93.71 %) and SW105 (93.63 %). The major respiratory quinone of wh15 was MK-6 and major fatty acids were iso-C, iso-C 3-OH, iso-C 3-OH, summed feature 3 (Cω7 and/or Cω6) and summed feature 9 (iso-Cω9 and/or C 10-methyl). The DNA G+C content of wh15 was 32.3 mol%. Phenotypic, phylogenetic and chemotaxonomic evidence indicated that wh15 represents a novel species of the genus , the name is proposed. The type strain is wh15 (=CCTCC AB 2015420=JCM 31173).
