ABSTRACT
A Gram-stain-negative, motile and rod-shaped bacterium, designated strain B2T, which can synthesize purple pigments of violacein and dexyoviolacein, was isolated from Tianshan glacier in Xinjiang, China. Phylogenetic analysis based on 16S rRNA gene sequences indicated that it was grouped in the genus Massilia with Massilia glaciei B448-2T, Massilia eurypsychrophila B528-3T and Massilia psychrophila B1555-1T as its closest relatives (98.2, 97.9 and 97.0â% 16S rRNA gene sequence similarity, respectively). Genomic relatedness between strain B2T and its closest relatives was evaluated using average nucleotide identity, digital DNA-DNA hybridization and average amino acid identity, with values of 77.93-85.08â%, 22.4-23.4â% and 71.54-72.99â%, respectively. Q-8 was the major ubiquinone. The major fatty acids (>5â%) of strain B2T were summed feature 3 (C16ââ1ω7c and/or C16ââ1ω6c), C12ââ0 and summed feature 8 (C18ââ1ω7c and/or C18ââ1ω6c). The major polar lipids included phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The DNA G+C content of strain B2T was 63.51 mol%. Based on genomic relatedness, physiological, biochemical and chemotaxonomic data, strain B2T (=CGMCC 1.6993T=DSM 19531T=KCTC 32446T) is considered to represent a novel species within the genus Massilia, for which the name Massilia violaceinigra sp. nov. is proposed.
