Ferruginibacter yonginensis sp. nov., isolated from a mesotrophic artificial lake

Abstract

A Gram-stain-negative, rod-shaped, aerobic and reddish-pigmented strain, designated HME8442(T), was isolated from a mesotrophic artificial lake. The strain grew optimally at 30 °C and pH 7 on R2A agar. The major fatty acid was iso-C15 : 0. The polar lipids were phosphatidylethanolamine, one unidentified aminolipid and three unidentified polar lipids. The predominant respiratory quinone was MK-7. The DNA G+C content was 35.8 mol%. Strain HME8442(T) was closely related to Ferruginibacter lapsinanis HU1-HG42(T) (94.4 % 16S rRNA gene sequence similarity) and Ferruginibacter alkalilentus HU1-GD23(T) (93.9 %). The phylogenetic tree based on 16S rRNA gene sequences showed that strain HME8442(T) formed a lineage within the genus Ferruginibacter. On the basis of the evidence presented in this study, strain HME8442(T) represents a novel species of the genus Ferruginibacter, for which the name Ferruginibacter yonginensis sp. nov. is proposed. The type strain is HME8442(T) ( = KACC 17314(T) = CECT 8289(T)).
