A Gram-negative, rod-shaped bacterium strain (K-39T) was isolated from the thermophilic phase of the composting process for oyster mushroom substrate preparation. The strain grew at 40-80 °C (optimum, 65-75 °C), at pH 5-9 (optimum, pH 7), in media containing up to 1.5% (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain K-39T formed a distinct lineage within the genus Thermus. Its closest cultivated relative was Thermus islandicus PRI 3838T (96.8% similarity). The DNA G+C content of strain K-39T was 71.3 mol%. The new strain could be differentiated from the related taxa by not being able to hydrolyze starch. The predominant fatty acids of strain K-39T were iso-C17:0 and anteiso-C17:0. Strain K-39T contained a lower amount of the fatty acid iso-C15:0 as compared to related Thermus species. The predominant respiratory quinone of the new isolate was menaquinone MK-8. On the basis of a polyphasic taxonomic study, strain K-39T is considered to represent a novel species of the genus Thermus, for which the name Thermus composti sp. nov. is proposed. The type strain is K-39T (=DSM 21686T=NCAIM B 02340T).
