title: [Production of a novel heparinase from Sphingobacterium sp].
abstract: The novel heparinase-producing bacterial strain Sphingobacterium sp. was isolated and screened from soil. The optimum medium composition is (g/L): Soytone 20, NaCl 1, K2HPO4 2.5, MgSO4 0.5, Heparin 2, Sucrose 15, pH 7.5. The optimum temperature for growth and enzyme production was 32 degrees C. When cultured at a rotating shaker at 30 degrees C for 36 hours, 200 r/min, 50 mL medium in 500 mL flask, the production of heparinase reached 4000 U/L.
