Catalase from bacillus and process for producing the same

A microbial catalase having a catalase activity at 0 DEG C. of 95% or more of its catalase activity at 30 DEG C., when measured at pH 7, and a process for producing the same. The microbial catalase preferably has (1) an operative temperature of 0 DEG to 60 DEG C. and an optimum temperature of 0 DEG...

Beschreibung
Zusammenfassung:	A microbial catalase having a catalase activity at 0 DEG C. of 95% or more of its catalase activity at 30 DEG C., when measured at pH 7, and a process for producing the same. The microbial catalase preferably has (1) an operative temperature of 0 DEG to 60 DEG C. and an optimum temperature of 0 DEG to 30 DEG C., when measured within the range of from 0 DEG to 60 DEG C., (2) an optimum pH of 7 to 10, (3) a resistance to 10 mM potassium fluoride, (4) a molecular weight is 65,000+/-3,000, when measured by SDS polyacrylamide gel electrophoresis, and (5) an isoelectric point is about 4.8, when measured by isoelectric focusing.
