- Abstract
A Gram-stain negative, aerobic, short rod-shaped, motile by flagella bacterial strain (THG-N2.35T), was isolated from Pu’er tea. Growth occurred at 10-40 °C (optimum 28 °C), at pH 4-7 (optimum 7) and at 0-5% NaCl (optimum 1%). Based on 16S rRNA gene sequence analysis, the near phylogenetic neighbours of strain THG-N2.35T were identified as Paracoccus hibisci KACC 18632T (99.0%), Paracoccus tibetensis CGMCC 1.8925T (98.7%), Paracoccus beibuensis CGMCC 1.7295T (98.2%), Paracoccus aestuarii KCTC 22049T (98.2%), Paracoccus rhizosphaerae LMG 26205T (98.1%), Paracoccus zeaxanthinifaciens ATCC 21588T (97.1%), Paracoccus marcusii DSM 11574T (97.0%). Levels of similarity between strain THG-N2.35T and other Paracoccus species were lower than 97.0%. DNA-DNA hybridization values between strain THG-N2.35T and P. hibisci KACC 18632T, P. tibetensis CGMCC 1.8925T, P. beibuensis CGMCC 1.7295T, P. aestuarii KCTC 22049T, P. rhizosphaerae LMG 26205T, P. zeaxanthinifaciens ATCC 21588T, P.marcusii DSM 11574T were 47.5% (42.3%, reciprocal analysis), 36.1% (32.3%), 24.7% (22.1%), 19.2% (16.3%), 11.3% (8.8%), 11.1% (10.8%), 6.1% (5.8%), respectively. The DNA G+C content of strain THG-N2.35T was 62.3 mol%. The polar lipids were diphosphatidylglycerol, phosphatidyl-N-methylethanolamine, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylcholine. The quinone was ubiquinone-10 (Q-10). The major fatty acids were C10:0 3OH, C16:0, C18:0 and C18:1ω7ϲ. On the basis of the phylogenetic analysis, chemotaxonomic data, physiological characteristics and DNA-DNA hybridization data, strain THG-N2.35T represent a novel species of the genus Paracoccus, for which the name Paracoccus pueri sp. nov. is proposed. The type strain is THG-N2.35T (= KACC 18934T = CCTCC AB 2016177T).
