Lacinutrix chionocetis sp. nov., isolated from gut of a red snow crab

A Gram-negative, aerobic, non-motile, rod-shaped bacterial strain, designated MAB-07 T , was isolated from the gut of a red snow crab. The novel strain grew optimally at 20 °C, pH 7.0–8.0, and in the presence of 3% (w/v) NaCl. A phylogenetic analysis based on the 16S rRNA gene sequence indicated that the strain MAB-07 T belongs to the type strains of species of the genus Lacinutrix . Strain MAB-07 T exhibited 16S rRNA gene sequence similarity values of 95.5–97.8% with the type strains of species of the genus Lacinutrix . The predominant cellular fatty acids of strain MAB-07 T were iso-C 15:1 G (27.5%) and iso-C 15:0 (21.7%). The major respiratory quinine was identified as MK-6. The polar lipids consisted of phosphatidylethanolamine, four unidentified aminolipids, and two unidentified lipids. The genomic DNA G + C content was determined to be 33.3%, and its DNA–DNA relatedness values with the type strains of L. venerupis , L. mariniflava , L. jangbogonensis , L. algicola , and Olleya aquimaris were 28–32%. Based on the data from this polyphasic taxonomic study, strain MAB-07 T is considered to represent a novel species of the genus Lacinutrix , for which the name L. chionocetis sp. nov. is proposed. The type strain is MAB-07 T (=KCTC 42767 T = JCM 30988 T ).
