Massilia agrisoli sp. nov., isolated from rhizospheric soil of banana
, Md. Fahadul Islam,

A Gram-stain-negative, aerobic, short rod-shaped and motile novel bacterial strain, designated MAHUQ-52T, was isolated from the rhizospheric soil of a banana plant. Colonies grew at 10–35 °C (optimum, 28 °C), pH 6.0–9.5 (optimum, pH 7.0–7.5), and in the presence of 0–1.0 % NaCl (optimum 0 %). The strain was positive for catalase and oxidase tests, as well as hydrolysis of gelatin, casein, starch and Tween 20. Based on the results of phylogenetic analysis using 16S rRNA gene and genome sequences, strain MAHUQ-52T clustered together within the genus Massilia . Strain MAHUQ-52T was closely related to Massilia soli R798T (98.6 %) and Massilia polaris RP-1-19T (98.3 %). The novel strain MAHUQ-52T has a draft genome size of 4 677 454 bp (25 contigs), annotated with 4193 protein-coding genes, 64 tRNA and 19 rRNA genes. The genomic DNA G+C content was 63.0 %. The average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH) values between strain MAHUQ-52T and closely related type strains were ≤88.4 and 35.8 %, respectively. The only respiratory quinone was ubiquinone-8. The major fatty acids were identified as C16 : 0 and summed feature 3 (C15 : 0 iso 2-OH and/or C16 : 1  ω7c). Strain MAHUQ-52T contained phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol as the major polar lipids. On the basis of dDDH and ANI values, as well as genotypic, chemotaxonomic and physiological data, strain MAHUQ-52T represents a novel species within the genus Massilia , for which the name Massilia agrisoli sp. nov. is proposed, with MAHUQ-52T (=KACC 21999T=CGMCC 1.18577T) as the type strain.
