Abstract
An enzymatic detergent and bleaching composition contains a bleaching system which is stronger than the sodium perborate/TAED system. In such a composition a lipase is employed which is produced by cloning, by rDNA technique, the gene which encodes the lipase produced by the fungas Humicola lanuginosa and expressing that gene in Aspergillus oryzae as host. The lipase is used in an amount giving a lipolytic enzyme activity of from 100 to 0.005 lipolytic units/mg of the composition.
