Olivibacter composti sp. nov., isolated from compost collected at a greenhouse
2017
A polyphasic approach was used to characterize a presumably novel bacterium, designated strain CC-KYC063T, isolated from a compost sample collected at a greenhouse facility within Taiwan. Strain CC-KYC063T was Gram-stain-negative and aerobic, able to grow at 15–37 °C (optimal 30 °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-KYC063T showed highest similarity to
Olivibacter ginsengisoli
Gsoil 060T (96.2 %) and
Olivibacter terrae
Jip13T (95.5 %). The DNA G+C content was 43.0 mol% and the predominant quinone system was menaquinone-7 (MK-7). The polyamine pattern showed a predominance of sym-homospermidine. The major fatty acids found in strain CC-KYC063T were iso-C15 : 0, iso-C17 : 0 3-OH and C16 : 1
ω6c/C16
: 1
ω7c. Based on the distinct phylogenetic, phenotypic and chemotaxonomic traits together with results of comparative 16S rRNA gene sequence analysis, strain CC-KYC063T 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 CC-KYC063T (=BCRC 80939T=JCM 31198T).
