Olivibacter composti sp nov., isolated from compost collected at a greenhouse

A polyphasic approach was used to characterize a presumably novel bacterium, designated strain CC-KYC063(T), isolated from a compost sample collected at a greenhouse facility within Taiwan. Strain CC-KYC063(T) was Gram-stain-negative and aerobic, able to grow at 15-37 degrees C (optimal 30 degrees C), at pH 7.0-9.0 (optimal pH 7.0) and with 0-2% (w/v) NaCl. The 16S rRNA gene sequence of strain CC-KYC063(T) showed highest similarity to Olivibacter ginsengisoli Gsoil 060(T) (96.2 %) and Olivibacter terrae Jip13(T) (95.5 %). showed a predominance of sym-homospermidine. The major fatty acids found in strain CC-KYC063(T) were iso-C-15:0, iso-C-17:0 3-OH and C-16:1 omega 6c/C-16:1 omega 7c. Based on the distinct phylogenetic, phenotypic and chemotaxonomic traits together with results of comparative 16S rRNA gene sequence analysis, strain CC-KYC063(T) is considered to represent a novel species of the genus Olivibacter, for which the name Olivibacter composti sp. nov. is proposed. The type strain is CCKYC063(T) (= BCRC 80939(T) = JCM 31198(T)).
