Abstract
|
|
|
1. The preparation and some enzymatic properties of crude alkaline protease from a thermophilic mold, Myriococcum sp. was investigated.
2. Optimum pH for the hydrolysis of casein was 9.0 at 50℃ for 10 minutes. Optimum temperature was 55℃ at pH 9.0 fur 10 minutes. The enzyme was highly stable at the range of pH 6.0 to 11.0 at 30℃
3. The alkaline protease in the culture filterate was isolated two fractions by elution column chromatography on DEAE-Cellulose.
