Massilia chloroacetimidivorans sp. nov., a chloroacetamide herbicide-degrading bacterium isolated from soil

Abstract

A Gram-stain negative, rod-shaped, aerobic bacterial strain, designated TA-C7e, was isolated from an agricultural soil obtained from Taean region, Korea. Phylogenetically, the strain was grouped with the genus Massilia and shared 95.33-97.97% 16S rRNA sequence similarity with the type strains of other species of the genus Massilia. The DNA-DNA hybridisation between TA-C7e and Massilia haematophila KACC 13771, Massilia suwonesis KACC 12635, and Massilia yuzhufengensis KACC 16569 revealed a low level of relatedness (<40%). The low levels of DNA-DNA hybridisation values identified strain TA-C7e as a novel species in the genus Massilia. The major fatty acids of the strain were C (37.3%) and summed feature 3 (C ω7c and/or C ω6c) (40.6%). Q-8 was identified as the only isoprenoid quinone. The polar lipids profile of the strain showed the presence of phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, an unidentified aminophospholipid and three unidentified lipids. The DNA G+C content of the strain was found to be 63.2 mol%. On the basis of the phenotypic, genotypic and chemotaxonomic characteristics, strain TA-C7e represents a novel species in the genus Massilia, for which the name Massilia chloroacetimidivorans sp. nov. (=KACC 18674 = NBRC 112463) is proposed.

Massilia arenae sp. nov., isolated from sand soil in the Qinghai–Tibetan Plateau

“…The DNA G+C content of GEM5 T was 65.1 mol% (). This was close to the genome DNA G+C contents of other type strains of species in the genus Massilia [3, 11, 12, 29]. Therefore, these results indicated that GEM5 T represented a novel species of the genus Massilia .…”

Influence of Salt Stress on Growth of Spermosphere Bacterial Communities in Different Peanut (Arachis hypogaea L.) Cultivars

“…Bacillus and Pseudarthrobacter significantly increased in salt-treated spermosphere soil groups compared with CS25 and CS20 via taxonomic analysis and qPCR assays (Figures 3 and 8). The two dominant bacteria genera in salt-treated spermosphere soil groups have previously been identified as common plant growth-promoting bacteria (PGPRs) [35][36][37][38]. Phosphorus is one of the essential mineral elements for plant growth, which is one of the major constituents in energy metabolism and biosynthesis of nucleic acids and cell membranes [39,40].…”

Genome insight and description of antibiotic producing Massilia antibiotica sp. nov., isolated from oil-contaminated soil

“…Some members have propensity to produce bioactive substance such as dimethyl disulfide (DMDS), which could have potential for controlling plant foliar diseases 10 . In addition, M. chloroacetimidivorans has been reported to degrade chloroacetamide herbicide 22 . On the other hand, some species such as M. timonae , M. consociate , M. oculi and M. haematophila are considered as pathogenic strains as they were isolated from human clinical samples 7 , 8 , 18 .…”
