Fulvimonas yonginensis sp. nov., isolated from greenhouse soil, and emended description of the genus Fulvimonas.

A novel strain, designated 5GHs31-2(T), was isolated from a greenhouse soil sample collected from Yongin city, South Korea. Cells of strain 5GHs31-2(T) were Gram-stain-negative, rod-shaped, polar flagellated and yellow-pigmented. The isolate was aerobic, catalase-negative and oxidase-positive and grew optimally at 28-30 °C and pH 7.0. Strain 5GHs31-2(T) revealed the highest 16S rRNA gene sequence similarities with Fulvimonas soli LMG 19981(T) (97.6%), Dyella thiooxydans ATSB10(T) (97.5%) and Frateuria terrea VA24(T) (97.4%). Furthermore, the neighbour-joining tree showed that strain 5GHs31-2(T) was a representative of a member of the genus Fulvimonas. Strain 5GHs31-2(T) contained iso-C(16 : 0), summed feature 9 (iso-C(17 : 1)ω9c and/or C(16 : 0) 10-methyl), iso-C(15 : 0) and iso-C(17 : 0) as the major fatty acids, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and an aminolipid as the main polar lipids and Q-8 as the predominant quinone. The genomic DNA G+C content of 5GHs31-2(T) was 73.0 mol%. According to DNA-DNA hybridization experiments, DNA-DNA relatedness values between strain 5GHs31-2(T) and its closest phylogenetic neighbours were below 70%. Based on the taxonomic data, strain 5GHs31-2(T) represents a novel species of the genus Fulvimonas, for which the name Fulvimonas yonginensis sp. nov. is proposed. The type strain is 5GHs31-2(T) ( = KACC 16952(T) = DSM 28344(T)).
