Massilia dura sp. nov., Massilia albidiflava sp. nov., Massilia plicata sp. nov. and Massilia lutea sp. nov., isolated from soils in China.

Four Gram-negative, motile, rod-shaped bacterial strains were isolated from soil samples collected from south-east China. A taxonomic study including phylogenetic analysis based on 16S rRNA gene sequences and phenotypic characteristics was performed. DNA G+C contents of the four strains were 63-66 mol%. Their predominant ubiquinone was Q-8. The fatty acid profiles contained C16:1omega7c (36.9-54.7%) and C16:0 (22.8-25.5%) as the major components. Based on their phenotypic characteristics, phylogenetic position as determined by 16S rRNA gene sequence analysis and DNA-DNA hybridization results, the four isolates are considered to represent four novel species of the genus Massilia, for which the names Massilia dura sp. nov. (type strain 16T=CCTCC AB 204070T=KCTC 12342T), Massilia albidiflava sp. nov. (type strain 45T=CCTCC AB 204071T=KCTC 12343T), Massilia plicata sp. nov. (type strain 76T=CCTCC AB 204072T=KCTC 12344T) and Massilia lutea sp. nov. (type strain 101T=CCTCC AB 204073T=KCTC 12345T) are proposed.
