Abstract:
A taxonomic study was carried out on a novel bacterial strain, designated MIC3010(T), which was isolated from a freshwater pond in Jeonju, Republic of Korea. Cells of the isolate were Gram-stain-negative, rod-shaped and non-motile. Comparison of the 16S rRNA gene sequences indicated that the isolate belonged to the family Flavobacteriaceae, with Flavobacterium haoranii LQY-7(T) as its closest relative, with a similarity of 94.2 %. The predominant fatty acids of strain MIC3010(T) were iso-C15 : 1 G, iso-C15 : 0 and iso-C17 : 0 3-OH. The polar lipid profile of strain MIC3010(T) revealed the presence of phosphatidylethanolamine (PE) and one unidentified lipid (L1) as major components. In addition, two aminolipids (AL1, AL2) and one glycolipid were present in small amounts. The DNA G+C content of the strain was 41.0 mol%. The strain contained MK-6 as the major quinone and sym-homospermidine as the predominant polyamine. On the basis of the evidence presented, it is concluded that strain MIC3010(T) represents a novel species of the genus Flavobacterium, for which the name Flavobacterium fontis sp. nov. is proposed. The type strain is MIC3010(T) ( = KACC 16593(T) = JCM 18212(T)).
