A Gram-stain-negative, pink bacterial strain, designated PR0008K(T), was isolated from an automobile evaporator core in Korea. The cells were obligately aerobic and rod-shaped. The strain grew at 10-40 degrees C (optimum, 20 degrees C), at pH 5-8 (optimum, 7), and in the presence of 0-1.5 % (w/v) NaCl. Phylogenetically, the strain was closely related to members of the genus Mucilaginibacter (93.4-97.0 % 16S rRNA sequence similarities) and showed a high sequence similarity with Mucilaginibacter litoreus BR-18(T), Mucilaginibacter lutimaris BR-3(T) and Mucilaginibacter soli R9-65(T) (97.0 %, 96.9 % and 96.9 % 16S rRNA sequence similarity, respectively). It contained summed feature 3 (C-16 : 1 omega 7c and/or C-16 : 1 omega 6c), C-16 : 0, iso-C-17 : 0 3-OH and C-16 : 0 as the predominant fatty acids and MK-7 as the major menaquinone. The polar lipids were phosphatidylethanolamine, one unknown aminophospholipid, two unknown aminolipids and two unknown polar lipids. The DNA G+ C content of this strain was 47.4 mol%. Based on the phenotypic, genotypic and chemotaxonomic data, strain PR0008K(T) represents a novel species in the genus Mucilaginibacter, for which the name Mucilaginibacter carri sp. nov. (=KACC 17938(T) =NBRC 111539(T)) is proposed.
