abstract= Strain 06168H-1T was isolated from a fishpond sediment sample collected from the southern area of Taiwan, and a polyphasic approach was used to determine its taxonomic position. The isolate grew between 20–40 °C and 0–8 % (w/v) NaCl. It produced branched and unfragmented substrate mycelia. Short spore chains (3–10 spores per chain) formed on branched aerial mycelia. The spore chains contained non-motile, smooth-surfaced, oval spores. Galactose, arabinose and ribose were the whole-cell sugars and meso-diaminopimelic acid was present in its peptidoglycan. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidylcholine, hydroxyphosphati dylethanolamine and a ninhydrin-positive phosphoglycolipid. The predominant menaquinone was MK-9(H4) and minor components were MK-8(H4) and MK-9(H6). Mycolic acids were not detected. The major cellular fatty acids were iso-C16 : 0 and C17 : 1ω6c and C17 : 0ω8c. The DNA G+C content of the strain was 70.6 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed this strain clustered with the members of the genus Saccharomonospora and was closely related to Saccharomonospora xinjiangensis , Saccharomonospora azurea and Saccharomonosporacyanea. The levels of similarity between this strain and the closely related species were: Sxinjiangensis BCRC16887T, 98.34 %; S. azurea BCRC 16220T, 98.27 %; and S. cyanea BCRC 16886T, 97.99 %. Based on phylogenetic characteristics, strain 06168H-1T represents a novel species of the genus Saccharomonospora . We thus propose the name Saccharomonospora piscinae sp. nov. for this novel strain, with strain 06168H-1T (=BCRC 16893T=KCTC 19743T) as the type strain.,
