A Gram-positive, aerobic, motile and short rod-shaped bacterium, designated as strain G56ᵀ, was isolated from shrimp paste produced in Panjin, China. Grows in the presence of 1.0–25.0% (w/v) NaCl (optimum at 10%), pH 5.0–9.5 (optimally at 7.0) and 10–50 °C (optimally at 37 °C). Positive for catalase and oxidase activities, but lack the ability to reduce nitrate. Acids produce from D-ribose, D-xylose, D-galactose, glycerol and D-trehalose, but no acid is produced when salicin, D-mannose, D-cellobiose and L-sorbose are provided as substrates. The polar lipid extract is found to contain diphosphatidylglycerol, phosphatidylglycerol, an unknown glycolipid, and unidentified phospholipids. Fatty acids are mainly defined as anteiso-C₁₅:₀ (69.7%) and anteiso-C₁₇:₀ (23.3%). The G+C content of its DNA is 44.7 mol%. The draft genome of strain G56ᵀ is 3,209,087 bp in length and the average nucleotide identity value (ANI) and the digital DNA-DNA hybridization (DDH) values between strain G56ᵀ and L. juripiscarius JCM 12147ᵀ is 78.41% and 22.0%, respectively. Polyphasic taxonomic analysis classified strain G56ᵀ as a novel species in the genus Lentibacillus, and therefore, we named it as Lentibacillus panjinensis sp. nov..
