A bacterial strain designated LYH-15T was isolated from a freshwater fish pond in Taiwan and characterized using a polyphasic taxonomy approach. Cells of LYH-15T were Gram-staining-negative, aerobic, motile by means of a single polar flagellum, poly-�]-hydroxybutyrate-containing, non-spore forming, straight rods and formed light-coral-colored colonies. Growth occurred at 15-40 �XC (optimum, 30 �XC), at pH 5.0-9.0 (optimum, pH 7.0) and with 0-0.5 % NaCl (optimum, 0 %). Phylogenetic analyses based on 16S rRNA gene sequences showed that LYH-15T forms a distinct phyletic line within the order Burkholderiales, with less than 94 % sequence similarity to its closest relatives with validly published names. The predominant fatty acids were summed feature 3 (comprising C16 : 1�s7c and/or C16 : 1�s6c), C16 : 0 and C18 : 1�s7c. The major isoprenoid quinone was Q-8 and the DNA G+C content was 63.8 mol%. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and several uncharacterized lipids. The major polyamines were 2-hydroxyputrescine and putrescine. On the basis of the genotypic and phenotypic data, LYH-15T represents a novel species of a new genus in the order Burkholderiales, for which the name Piscinibacterium candidicorallinum gen. nov., sp. nov. is proposed. The type strain is LYH-15T (=BCRC 80969T=LMG 29480T=KCTC 52168T).
