The transfer of a textile dye from a dyed fabric to another fabric during washing or rinsing is inhibited by adding an enzyme exhibiting peroxidase activity or an enzyme exhibiting a suitable oxidase activity to the wash liquor in which said fabrics are washed and/or rinsed. Peroxidase is produced extracellularly by some strains of Bacillus pumilus. The novel peroxidase preparation from B. pumilus is a microperoxidase, i.e. it contains hemopeptide as an active component. The preparation has improved stability at high temperature, at high pH and at high concentrations of hydrogen peroxide. It can be produced without undesired catalase activity.
