( 2018 ) Aquincola amnicola sp. nov., isolated from a freshwater river. PMID : 29442129 DOI : 10.1007/s00203-018-1492-4 Abstract >>
Strain TTM-94T, isolated from a water sample taken from the Caohu River in Taiwan, was characterized using a polyphasic taxonomic approach. Cells of strain TTM-94T were Gram-staining-negative, aerobic, poly-�]-hydroxybutyrate-accumulating, motile by a single polar flagellum, short rod-shaped and surrounded by a thick capsule and it formed cream colored colonies. Growth occurred at 20-30 �XC (optimum, 30 �XC), at pH 6.0-8.0 (optimum, pH 6.0), and in the presence of 0-2% NaCl (optimum 0.5%). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain TTM-94T belonged to the genus Aquincola in the Rubrivivax-Roseateles-Leptothrix-Ideonella-Aquabacterium branch of the class Betaproteobacteria and its most closely related neighbour was Aquincola tertiaricarbonis L10T with sequence similarity of 97.0%. Strain TTM-94T contained summed feature 3 (comprising C16:1�s7c and/or C16:1�s6c), C16:0 and C18:1�s7c as the predominant fatty acids. The polar lipid profile consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and several uncharacterized lipids. The major respiratory quinone was Q-8. Genomic DNA G + C content of strain TTM-94T was 70.7 mol%. Strain TTM-94T exhibited less than 30% DNA-DNA relatedness with A. tertiaricarbonis L10T. Differential phenotypic properties, together with the phylogenetic inference, demonstrate that strain TTM-94T should be classified as a novel species of the genus Aquincola, for which the name Aquincola amnicola sp. nov. is presented. The type strain is TTM-94T (= BCRC 80890T = LMG 28709T).
