Abstract
A Gram-stain-positive, facultatively anaerobic, rod-shaped bacterium, designated JX-17T, was isolated from a soil sample collected in Jiangxi Province, PR China. Growth was observed at 15-48 °C (optimum 37 °C), at pH 5.0-9.0 (optimum pH 7.0) and with 0-6.0% (w/v) NaCl (optimum 1.0%). Strain JX-17T could degrade approximately 50% of 50 mg/L mesotrione within 2 days of incubation, but could not use mesotrione as sole carbon source for growth. Strain JX-17T showed less than 95.3% 16S rRNA gene sequence similarity with type strains of the genus Paenibacillus. In the phylogenetic tree based on 16S rRNA gene and genome sequences, strain JX-17T formed a distinct lineage within the genus Paenibacillus. The ANI values between JX-17T and the most closely related type strains P. lentus CMG1240T and P. farraposensis UY79T were 70.1% and 71.4%, respectively, and the dDDH values between them were 19.0% and 23.3%, respectively. The major cellular fatty acids were anteiso-C15:0, iso-C16:0, anteiso-C17:0 and C16:0, the predominant respiratory quinone was MK-7, the major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, an unidentified glycolipid, an aminophospholipid and a phosphatidylinositol. The diagnostic diamino acid of the peptidoglycan was meso-diaminopimelic acid, and the DNA G + C content was 50.1 mol%. Based on the phylogenetic, phenotypic and chemotaxonomic characteristics, strain JX-17T represents a novel species within the genus Paenibacillus, for which the name Paenibacillus lacisoli sp. nov is proposed, with strain JX-17T (= GDMCC 1.3962T = KCTC 43568T) as the type strain.
