PROBLEM TO BE SOLVED: To provide a new species of bacterium having oil and fat- decomposability and a decomposing method of oil and fat by using the same. SOLUTION: In this invention, a new species of bacterium belonging to the genus Acinetobacter derived from rice bean, i.e., Acinetobacter sp. YU-1 is provided. This bacterium has an oil and fat-decomposing enzyme (lipase) activity. The lipase is an intracellular enzyme and has a high stability of the enzyme activity. When the bacterium is used in a meat processing factory, a bovine oil and fat is efficiently decomposed and an effect of removing dirts in an underdrain ditch, or the like is confirmed. |
