Abstract

A moderately thermophilic bacterium is described, strain N2-214, that was isolated from an enrichment culture, growing on caprolactone, obtained from a sample from a water-treatment sludge aerobic digester operating at temperatures around 60 °C. The organism was aerobic, Gram-negative, oxidase- and catalase-positive, with a polar flagellum, and capable of growth at temperatures as high as 61 °C. The major fatty acids of strain N2-214 were C, C and cyclo-C. The phylogenetic relationships of the strain, derived from 16S rRNA gene sequence comparisons, demonstrated it to be a member of the -subclass of the . The highest 16S rDNA sequence similarity of isolate N2-214 was to (91·9 %), (92 %) and (92·7 %). On the basis of phylogenetic analyses and physiological and chemotaxonomic characteristics, it is proposed that isolate N2-214 (=DSM 15129=LMG 21637) represents a new genus and species, gen. nov., sp. nov.
