DOIAbstract
A method was developed to perform PCR directly on mycelial pellets or colonies treated with NOVOzym 234. The method allows rapid screening of large numbers of transformants of both sporulating and non-sporulating fungi for the presence of (co)transforming plasmid copies or for specific genetic modifications such as gene disruption and site specific integration. PCR fragments of at least 3.2 kb can be obtained. Using this method the identification of specific disruption mutants from Aspergillus niger and Beauveria bassiana was carried out
