Abstract
Lipase-producing bacteria (S3) were isolated from intertidal flat at Saemanguem. A isolated strain was identified as Psychrobacter species by physiological and fermentational characterization as well as 16S rRNA analysis. The strain was then named as Psychrobacter sp. S3. P. sp. S3 grew most rapidly at $30^{\circ}C$, but grew well even at $10^{\circ}C$ and its lipase activity was most high when cultivated at $20^{\circ}C$. Lipase S3 had optimum temperature of $30^{\circ}C$ for the hydrolysis of p-nitrophenyl caproate and had more than $80^{\circ}C$ activity even at $10^{\circ}C$. The activation energy was calculated to be 1.5 kcal/mol, which showed that it was a typical cold-adapted enzyme. It was an alkaline enzyme with optimum pH of $9.0\~9.5$. It could hydrolyze various length of triglycerides. Among them, it hydrolyzed most rapidly $C_4,\;C_{14},\; C_{16}-length$ triglycerides. When added to tributyrin-agarose gel, lipase S3 hydrolyzed tributyrin most rapidly at 30 and $40^{\circ}C$, but it could hydrolyze well even at $4^{\circ}C$.
