    Abstract: PURPOSE: Provided is a microorganism strain producing thermophile lipase. The above strain is obtained from the soil samples near the industrial complex, identified as a novel lipase producing strain different from known Burkholderia cepacia and named as SY-02(Burkholderia cepacia SY-02). It shows thermo-stability and high enzyme activity at the higher temperature than the melting point of fat and is thus widely useful as a lipase producing strain in the field of industry. CONSTITUTION: The strain Burkholderia cepacis SY-02(KFCC-111210) produces thermophilic lipase which is secreted into the exterior of a cell of Burkholderia cepacia SY-02, and shows activity at 40-80 deg.C, preferably 70 deg.C.

CONSTITUTION: A process for preparing cis-2- (bromomethyl)-2- (2,4-dichlorophenyl)- 13-dioxolane- 4-methyl alcohol having high optical selectivity comprises hydrolysis of cis-2- (bromomethyl)-2- (2,4-dichlorophenyl)- 1,3-dioxolane- 4-methyl acetate using lipase produced from Acinetobacter sp. SY-01(KFCC-11111), and recovering an alcohol product as a reaction product from the reaction solution during the reaction, wherein the concentration of the alcohol product is 0.1 to 300 mg/l; the reaction product is recovered when the conversion rate of the hydrolysis reaction is 40 to 60%; the hydrolysis reaction is carried out under conditions of 40 to 60 deg. C, pH 7.0 to 9.0 and 100 to 300 rpm; and the reaction product is recovered by column chromatography.
