Abstract

A heavy metal-resistant and dimethyl disulfide-producing bacterial strain, designated 6NM-7T, was isolated from wolfram mine tailing, Dayu County, Jiangxi Province, PR China. Strain 6NM-7T was aerobic, Gram-stain-negative and motile by means of a single polar flagellum. Phylogenetic analysis, based on 16S rRNA gene sequences, showed that strain 6NM-7T was affiliated with the genus Massilia and was closely related to Massilia norwichensis LMG 28164T (98.8 % 16S rRNA gene sequence similarity), Massilia kyonggiensis KACC 17471T (98.4 %), Massilia niastensis KACC 12599T (97.8 %), Massilia tieshanensis KACC 14940T (97.3 %), Massilia haematophila KACC 13771T (97.2 %), Massilia namucuonensis CGMCC 1.11014T (97.1 %) and Massilia aerilata KACC 12505T (97.1 %). The DNA-DNA relatedness values between strain 6NM-7T and its closely related type strains were all below 70 %. The major respiratory quinone was unbiquinone 8 (Q-8) and the major cellular fatty acids consisted of C16 : 0 (33.2 %), summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH; 21.8 %), C17 : 0 cyclo (20.8 %), C18 : 1ω7c (7.4 %) and C10 : 0 3-OH (5.8 %). The major polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The genomic DNA G+C content of strain 6NM-7T was 66.8 ± 0.6 mol%. On the basis of the results of this polyphasic taxonomic study, strain 6NM-7T should be assigned to a novel species of the genus Massilia, for which the name Massilia putida sp. nov. is proposed. The type strain is 6NM-7T ( = DSM 27523T = KCTC 42761T).
