Abstract:
A novel bacterial strain, designated SA3-7(T), was isolated from soil of a lava forest located in Jeju, Republic of Korea. Cells of strain SA3-7(T) were Gram-stain-negative, oxidase- and catalase-positive, non-motile rods and produced creamy white colonies on ten-fold-diluted R2A agar. The isolate contained menaquinone-7 (MK-7) as the predominant isoprenoid quinone and summed feature 3 (C16 : 1ω7c/C16 : 1ω6c), iso-C15 : 0 and iso-C17 : 0 3-OH as the major fatty acids. The DNA G+C content was 43.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequencing showed that strain SA3-7(T) was related most closely to Mucilaginibacter frigoritolerans FT22(T) (96.7 % sequence similarity) and that it formed a separate lineage in the genus Mucilaginibacter. Combined phenotypic, chemotaxonomic and phylogenetic characteristics supported the conclusion that strain SA3-7(T) represents a novel species of the genus Mucilaginibacter, for which the name Mucilaginibacter gotjawali sp. nov. is proposed; the type strain is SA3-7(T) ( = KCTC 32515(T) = CECT 8628(T) = DSM 29289(T)).
