ABSTRACT
Two Gram-stain-negative, aerobic, motile and short rod strains, designated 4D117T and ZD32-2T, were isolated from the forest soils. Strains 4D117T and ZD32-2T grew optimally at pH 4.0-6.5, 20-33 °C and pH 4.5-7.0, 33 °C, respectively, and both at 0.5% (w/v) NaCl concentration. Strains 4D117T and ZD32-2T shared the highest 16S rRNA gene sequence similarity with P. acidiphila 7Q-K02T (99.1%) and P. ferrariae NBRC 106233T (98.7%), respectively. The genome size and G + C contents of strains 4D117T and ZD32-2T were 9,002,095 bp, 62.9% and 6,974,420 bp, 61.7%, respectively. The dDDH and ANI values between strains 4D117T, ZD32-2T and closely related Paraburkholderia species were in the ranges of 21.9-51.6% and 82.9-94.4%, and 81.7% and 25.4% between themself, respectively. Functional genomic analysis showed both strains were capable of degrading contaminants, such as benzoate, anthranilic acid and catechol for 4D117T, and benzene and catechol for ZD32-2T, indicating that they may have potentials for soil pollutant treatment. The main polar lipids of strains 4D117T and ZD32-2T were phosphatidylglycerol, phosphatidylethanolamine and diphosphatidylglycerol. Strain 4D117T contained C160, C190 cyclo ω8c and C181 ω7c and/or C181 ω6c, while strain ZD32-2T had C160 and C170 cyclo as their major cellular fatty acids (> 10%). Based on the phenotypic characters and genomic data, strains 4D117T and ZD32-2T represent two novel species of genus Paraburkholderia, for which the names Paraburkholderia flagellata sp. nov. (type strain 4D117T = GDMCC 1.2617T = NBRC 115278T) and Paraburkholderia adhaesiva sp. nov. (type strain ZD32-2T = GDMCC 1.2622T = NBRC 115282T) are proposed.
