Abstract
The present invention relates to a mutant microbial host cell which has been modified, preferably in its genome, to result in a deficiency in the production of a polypeptide having α-amylase activity AmyC or an homologous thereof. It has been surprisingly found that when the mutant microbial host cell according to the invention is used in a method to produce a compound of interest, for example an enzyme, an improved purity of the product is obtained.
