Description. [0001]. The present invention discloses selection marker gene free recombinant filamentous fungal strains, a method for obtaining these strains and the use of these strains. Furthermore, the method of the present invention is used for performing strain improvement.o grow on acetamide as the sole N-source. For microorganisms that lack the possibility or only have a very limited capacity to use acetamide as the sole N-source the acetamidase gene can in principle be used as a selection marker provided that acetamide is taken up by the cells.
