Abstract

The present invention provides a process for stabilizing the activity of peroxidase in solution by the addition of a specific activity stabilizer, wherein, to the enzyme present in solid or dissolved form, there is added, as activity stabilizer, phenol which optionally contains one or more substituents selected from lower alkyl radicals and chlorine and bromine atoms, in an amount of from 0.0005 to 2% by weight, referred to the solution.
