Deinococcus piscis sp. nov., a radiation-resistant bacterium isolated from a marine fish Shashidhar, Ravindranath and Bandekar, Jayant R.,, 59, 2714-2717 (2009), doi = https://doi.org/10.1099/ijs.0.003046-0, publicationName = Microbiology Society, issn = 1466-5026, abstract= A radiation-resistant, Gram-stain-positive, non-motile, non-sporulating, aerobic, coccoid bacterium, strain 3axT, was isolated from a marine fish (black pomfret, Parastromateus niger), with radiation as a selective pressure. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain 3axT exhibited highest similarity (97.9 %) with Deinococcus proteolyticus DSM 20540T. The ΔT m for DNA–DNA hybridization of D. proteolyticus DSM 20540T and strain 3axT was 15.3 °C, indicating that the novel strain was distinct from D. proteolyticus DSM 20540T. The predominant respiratory quinone was MK-8. Strain 3axT could grow at 20–42 °C; the optimum temperature for growth was 35 °C. The strain grew well at pH 6–9, with optimum growth at pH 7. The cell wall contained ornithine. The major fatty acids were 16 : 0, 16 : 1ω7c, 16 : 1ω9c and 18 : 1ω9c. Three phosphoglycolipids and one aminophospholipid were the major polar lipids. Based on the genotypic, phenotypic and chemotaxonomic characteristics, strain 3axT was significantly different from D. proteolyticus DSM 20540T and, therefore, it was identified as representing a novel species of the genus Deinococcus, for which the name Deinococcus piscis sp. nov. is proposed. The type strain is 3axT (=MTCC9123T =DSM 19767T)., language=, type=
