A novel strain, NJ-8(T), was isolated from sediment of the eutrophic Taihu Lake (China) and was subjected to a taxonomic study by using a polyphasic approach. The novel strain was aerobic and formed orange-pigmented colonies on R2A agar. Cells were Gram-negative single rods that were motile by means of gliding. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain NJ-8(T) belonged to the phylum Bacteroidetes, with Niastella yeongjuensis DSM 17621(T)(92.3% gene sequence similarity) and Niastella koreensis DSM 17620(T) (92.0% similarity) as its closest relatives. The major fatty acids (> 5% of the total) were iso-C-15:0 (27.8%), iso-C-15:1 G (15.4%), iso-C-17:0 3-OH (14.5%) and summed feature 3 (comprising C-16:1 omega 7c and/or iso-C-15:0 2-OH; 13.9%). The genomic DNA G + C content was 46.6 mol%. Based on molecular and phenotypic data, strain NJ-8(T) is considered to represent a novel species of a new genus, for which the name Lacibacter cauensis gen. nov., sp. nov. is proposed. The type strain of the type species of the genus, Lacibacter cauensis, is NJ-8(T) (=CGMCC 1.7271(T)=NBRC 104930(T)).
