Lentibacillus panjinensissp. nov., Isolated from Shrimp Paste, a Traditional Chinese Fermented Seafood
A Gram-positive, aerobic, motile and short rod-shaped bacterium, designated as strain G56(T), 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 degrees C (optimally at 37 degrees C). Positive for catalase and oxidase activities, but lack the ability to reduce nitrate. Acids produce fromd-ribose,d-xylose,d-galactose, glycerol andd-trehalose, but no acid is produced when salicin,d-mannose,d-cellobiose andl-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-C-15:0(69.7%) and anteiso-C-17:0(23.3%). The G+C content of its DNA is 44.7 mol%. The draft genome of strain G56(T)is 3,209,087 bp in length and the average nucleotide identity value (ANI) and the digital DNA-DNA hybridization (DDH) values between strain G56(T)andL. juripiscariusJCM 12147(T)is 78.41% and 22.0%, respectively. Polyphasic taxonomic analysis classified strain G56(T)as a novel species in the genusLentibacillus, and therefore, we named it asLentibacillus panjinensissp. nov..
