title: Wenzhouxiangella marina gen. nov, sp. nov, a marine bacterium from the culture broth of Picochlorum sp. 122, and proposal of Wenzhouxiangellaceae fam. nov. in the order Chromatiales.
abstract: A Gram-stain negative, non-motile, non-phototrophic, non-alkaliphilic, obligately aerobic, chemoheterotrophic, and rod-shaped bacterium, designated strain Ma-11(T), was isolated from the culture broth of a marine microalga, Picochloruma sp. 122. Phylogenetic analyses showed that strain Ma-11(T) has less than 91 % similarity to its closest relative, Thioalkalivibrio sulfidiphilus HL-EbGR7(T), represents a distinct phylogenetic lineage in the order Chromatiales, and could not be assigned to any defined families in this order. Chemotaxonomic, genetic and physiological characteristics, including major fatty acids, genomic G+C content, lack of motility, aerophilicity and chemoheterotrophicity, could readily distinguish strain Ma-11(T) from any established members of the order Chromatiales. Based on the 16S rRNA gene sequence analysis and its signature nucleotide pattern, a new family Wenzhouxiangellaceae fam. nov. comprising the genus Wenzhouxiangella gen. nov. and species Wenzhouxiangella marina sp. nov. is proposed. The type strain is Ma-11(T) (=CGMCC 1.14936(T) = KCTC 42284(T) = MCCC 1K00261(T)).
