Abstract

A method for degrading nucleic acids in a waste fermentation solution is disclosed. The method comprises exposing the waste solution to RNases and/or DNases released by autolysis of and/or secreted from Paecilomyces lilaninus which are present in or added to the waste solution. The fermentation of the microorganism occurs under sterile conditions. The microorganism can be transformed with nuclease-encoding genes and added to the waste solution before fermentation. The preferred strain of Paecilomyces lilacinus is DSM 5650.
