Abstract:
:A strictly aerobic, Gram-stain-negative, rod-shaped, motile by gliding and yellow-pigmented bacterium, designated strain 7Alg 4T, was isolated from the green alga Cladophora stimpsonii. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the novel strain was affiliated to the family Flavobacteriaceae of the phylum Bacteroidetes, and was most closely related to the recognized species of the genera Lacinutrixand Flavirhabdus, with 16S rRNA gene sequence similarities of 95.1-98.1 and 97.0 %, respectively. Strain 7Alg 4T grew in the presence of 1-5 % NaCl and at 4-32 °C, and hydrolysed aesculin, gelatin, starch and Tween 80. The prevalent fatty acids were iso-C15 : 1 G, iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 0 3-OH and C15 : 0. The polar lipid profile was characterized by the presence of phosphatidylethanolamine, three unidentified aminolipids and four unidentified lipids. The major respiratory quinone was MK-6. The DNA G+C content was 31.9 mol%. On the basis of the differences in 16S rRNA gene sequences, chemotaxonomic and phenotypic characteristics, it is suggested that strain 7Alg 4T represents a novel species of the genus Lacinutrix, for which the name Lacinutrixcladophorae sp. nov. is proposed. The type strain is 7Alg 4T (=KCTC 23036T=KMM 6381T). Reclassification of Flavirhabdus iliipiscaria as Lacinutrix iliipiscaria comb. nov. and an emend of the genus Lacinutrix are also proposed.
