Abstract
|
|
|
(1) The 30 strains of Penicillia and the 52 strains of Aspergilli have been screened for their producibility of 5´-Phosphodiesterase, and Penicillium sclerotiorum 7321. Penicillium sp M-11 and Penicillium citrinum UV-mutant 2032-72 were selected as having high 5´-Phosphodiesterase activity.
(2) Using the wheat bran medium the 5´-Phosphodiesterase production was reached at maximum state by the plate culture for 10 days at 30℃
(3) The optimum conditions of the 5´-phosphodiesterase activity of Penicillium sclerotiorum 7321 and Penicilliurn sp M-11 were pH 4.0 at 62.5℃, while the optimum condition of the 5´-Phosphodiesterase activity of Penicillium citrinum UV-mutant 2032-72 was pH 5.0 at 50℃.
