Abstract:
A Gram-stain-negative and rod-shaped bacterial strain, 12-OD1T, with rock phosphate solubilizing ability was isolated from agricultural soil in Hailun, Heilongjiang, PR China. The isolate was affiliated to the genus Massilia, based on 16S rRNA gene sequence alignments, having the highest similarities with Massilia putida6 NM-7T (98.67 %), Massilia kyonggiensis TSA1T (98.28 %), and Massilia norwichensis NS9T (98.07 %), respectively. The DNA G+C content was 67.72 mol% and DNA-DNA hybridization showed low relatedness values (less than 47 %) between strain 12-OD1T and other phylogenetically related species of the genus Massilia. The predominant isoprenoid quinone was Q-8 and the polar lipid profile comprised diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The major fatty acids were C17 : 0 cyclo (25.4 %), C16 : 0 (23.4 %) and summed feature 3 (C16 : 1ω7c and/or C16 : 1 ω6c) (22.5 %), which differentiates it from close relatives within the genus Massilia. Combined genetic, physiological and biochemical properties indicate that strain 12-OD1T is a novel species of the genus Massilia, for which the name Massilia phosphatilytica sp. nov., is proposed, with the type strain 12-OD1T (=CCTCC AB 2016251T=LMG 29956T=KCTC 52513T).
