Thalassospira tepidiphila sp. nov., a polycyclic aromatic hydrocarbon-degrading bacterium isolated from seawater Kodama, Yumiko and Stiknowati, Lies Indah and Ueki, Atsuko and Ueki, Katsuji and Watanabe, Kazuya,, 58, 711-715 (2008), doi = https://doi.org/10.1099/ijs.0.65476-0, publicationName = Microbiology Society, issn = 1466-5026, abstract= A Gram-negative, mesophilic bacterial strain, designated 1-1BT, which degrades polycyclic aromatic hydrocarbons, was isolated from petroleum-contaminated seawater during a bioremediation experiment. A 16S rRNA gene sequence analysis indicated that the isolate was affiliated with the genus Thalassospira in the Alphaproteobacteria; the sequence was found to be most similar to those of Thalassospira profundimaris WP0211T (99.8 %), Thalassospira xiamenensis M-5T (98.2 %) and Thalassospira lucentensis DSM 14000T (98.1 %). However, the levels of DNA–DNA relatedness between strain 1-1BT and these type strains were 50.7±17.2, 35.7±17.8 and 32.0±21.1 %, respectively. In addition, strain 1-1BT was found to be distinct from the other described species of the genus Thalassospira in terms of some taxonomically important traits, including DNA G+C content, optimum growth temperature, salinity tolerance, utilization of carbon sources and fatty acid composition. Furthermore, strain 1-1BT and T. profundimaris were also different with regard to motility and denitrification capacities. On the basis of physiological and DNA–DNA hybridization data, strain 1-1BT represents a novel species within the genus Thalassospira, for which the name Thalassospira tepidiphila sp. nov. is proposed. The type strain is 1-1BT (=JCM 14578T =DSM 18888T)., language=, type=
