Abstract

The taxonomic position of a chlorophenol-degrading bacterium, strain S37, was investigated. The 16S rDNA sequence indicated that this strain belongs to the genus , exhibiting high sequence similarity to the 16S rDNA sequences of LMG 18877 (98·8 %), LMG 17324 (98·2 %), IFO 15098 (95 %) and GIFU 11458 (92 %). These strains (except IFO 15098, which was not investigated) and the novel isolate accumulated polyhydroxyalkanoates consisting of 3-hydroxybutyric acid and 3-hydroxyvaleric acid from glucose as carbon source. The G+C content of the DNA of strain S37 was 65·5 mol%. The major cellular fatty acids of this strain were octadecenoic acid (18 : 17), heptadecenoic acid (17 : 16) and hexadecanoic acid (16 : 0). The results of DNA–DNA hybridization experiments and its physiological characteristics clearly distinguished the novel isolate from all known species and indicated that the strain represents a novel species. Therefore, the species sp. nov. is proposed, with strain S37 (=LMG 20986 =DSM 14889) as the type strain. The transfer of to the genus as comb. nov. is also proposed.
