摘要： A gram-staining-positive, rod-shaped bacterium, designed strain FJAT-51161(T) was isolated from farmland soil collected from Fujian Province, China. Growth was observed at 25-40 degrees C (optimum 30 degrees C), pH 7.0-9.0 (optimum 7.0), and NaCl tolerance in the range of 0-7% (w/v), respectively. Phylogenetic analysis based on the 16S rRNA gene sequences indicated that the strain FJAT-51161(T) belonged to the genus Lysinibacillus, and had the closest relationship with Lysinibacillus xylanilyticus XDB9(T) (99.0% 16S rRNA sequence similarity). The digital DNA-DNA hybridization (dDDH) and average nucleotide identity (ANI) values based on the genome sequence analysis between strain FJAT-51161(T) and the closest reference strain were 38.0% for dDDH and 88.7% for ANI, respectively, lower than the prokaryotic species delineation values. Further analysis showed that strain FJAT-51161(T) shared the fatty acid profiles such as iso-C-15:0 (46.7%), iso-C-16:0 (15.8%), C-16:1 omega 7c alcohol (14.0%), anteiso-C-15:0 (6.9%) with other members of the genus Lysinibacillus. As the peptidoglycan contained the amino acids alanine, lysine, glycine and aspartic acid, the type A4 alpha was deduced as found in the closest relatives of strain FJAT-51161(T). The peptidoglycan of strain FJAT-51161(T) was L-Lys-D-Asp (type A4 alpha). The main quinone was MK-7 and MK-6. The major polar lipids were diphosphatidylglycerol (DPG) and phosphatidylethanolamine (PE). The DNA G + C content is 36.6 mol%. Based on the phenotypic characters and taxono-genomics study, strain FJAT-51161(T) is considered to represent a novel Lysinibacillus species, for which the name Lysinibacillus agricola sp. nov. is proposed. The type strain is FJAT-51161(T) (GDMCC1.2350(T) = KCTC 43326(T)).
