Abstract
A Gram-stain-negative, non-motile, rod-shaped, aerobic bacterial strain, designated HC2T, was isolated from the phycosphere of Haematococcus lacustris NIES 144 culture. Strain HC2T was able to grow at pH 4.5-8.0, at 4-32 °C and in the presence of 0-2 % (w/v) NaCl. Phylogenetic analysis of the 16S rRNA gene sequence revealed that strain HC2T was affiliated to the genus Mucilaginibacter and shared the highest sequence similarity with Mucilaginibacter lappiensis ANJKI2T (98.20 %) and Mucilaginibacter sabulilitoris SMS-12T (98.06 %). Strain HC2T contained summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c) and iso-C15 : 0 as the major fatty acids (>10.0 %). The major polar lipids were phosphatidylethanolamine, one unidentified aminophospholipid, one unidentified phospholipid, two unidentified aminolipids and four unidentified lipids. The respiratory quinone was menaquinone 7 (MK-7). The genomic DNA G+C content was 42.0 %. On the basis of the phenotypic, chemotaxonomic and phylogenetic characteristics, strain HC2T represents a novel species of the genus Mucilaginibacter, for which the name Mucilaginibacter inviolabilis sp. nov. is proposed. The type strain is HC2T (=KCTC 82084T=JCM 34116T).
