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

Whole-Genome Sequence of French Clinical Olivibacter jilunii Strain P8502

In 2013, Olivibacter jilunii was reported as a bacterial species isolated from contaminated soil. In 2018, a clinical strain from the same species was isolated from the rectal swab of a Hajj pilgrim. Genome sequencing yielded 6,704,032 bp, with 41.2% G+C content, 5,406 protein-coding genes, and 54 predicted RNA genes in strain P8502.

Olivibacter ginsenosidimutans sp nov., with ginsenoside converting activity isolated from compost, and reclassification of Pseudosphingobacterium domesticum as Olivibacter domesticus comb. nov

A Gram-stain-negative, aerobic and rod-shaped, bacterium designated as strain BS18^T, was isolated from compost and subjected to a polyphasic taxonomic analysis. On the basis of the results of 16S rRNA gene sequence analysis, BS18^T represents a member of the genus Olivibacter of the family Sphingobacteriaceaeand is most closely related to Olivibacter oleidegradansTBF2/20.2^T (93.7 %), Olivibacter jilunii 14-2A^T (93.6 %), Olivibacter ginsengisoli Gsoil 060^T (93.6 %), Pseudosphingobacterium domesticumDC186^T (93.0 %) and shared ≤93.1 % sequence similarity with the other members of the genus Olivibacter. BS18^T contained MK-7 as the predominant quinone, iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 4 (iso-C15 : 0 2-OH and/or C16 : 1ω7c), as the major fatty acids and phosphatidylethanolamine (PE) as main polar lipid. BS18^T could be distinguished from the other members of the genus Olivibacter by a number of chemotaxonomic and phenotypic characteristics. On the basis of the results of polyphasic taxonomic analysis, BS18^T represents a novel species within the genus, for which the name Olivibacter ginsenosidimutans sp. nov. is proposed. The type strain of Olivibacter ginsenosidimutans is BS18^T (=KACC 16612^T=JCM 18200^T). It is also proposed to transfer Pseudosphingobacterium domesticumto the genus Olivibacter, as Olivibacter domesticus comb. nov. (type strain DC186^T=CCUG 54353^T=LMG 23837^T).
