Abstract

A novel bacterial strain, designated KBP-13, was isolated from a water sample taken from the Banping Lake Wetland Park in Taiwan and characterized using a polyphasic taxonomic approach. Cells of strain KBP-13 were Gram-stain-negative, aerobic, poly--hydroxybutyrate-accumulating, motile rods that formed light yellow colonies. Growth occurred at 15–40 °C (optimum, 30–40 °C), at pH 6.0–8.0 (optimum, pH 6.0) and with 0–2 % (w/v) NaCl (optimum, 0 %). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain KBP-13 belonged to the genus within the family of the class and its most closely related neighbour was 5YN10-9 with sequence similarity of 96.0 %. Strain KBP-13 contained summed feature 3 (comprising C 7 and/or C 6), C and C as predominant fatty acids. The major respiratory quinone was Q-8. The DNA G+C content of the genomic DNA was 65.1 mol%. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, one uncharacterized aminophospholipid, one uncharacterized aminolipid, two uncharacterized phospholipids and three uncharacterized glycolipids. On the basis of the genotypic, chemotaxonomic and phenotypic data, strain KBP-13 represents a novel species in the genus , for which the name sp. nov. is proposed. The type strain is KBP-13 (=BCRC 80903=LMG 28837=KCTC 42655).
