โฆ Synopsis
A number of mutants of Aspergillus niger, affected in glucose oxidase (GOX) expression, are described. The overproducing mutants could be classified into seven complementation groups whereas two glucose oxidase-negative complementation groups were recognized. These nine gox loci were assigned to linkage groups using master strains with marked chromosomes. Three gox loci are in linkage group II, one is in III, two are in V and two are in linkage group VII. One weak glucose oxidase-overproducing mutant could not be assigned to one of the linkage groups. These genetically well characterized mutants will be used in a strain improvement program based on genetic recombination.

A start has been made on establishing a collection of Aspergillus niger colour and auxotrophic mutants with an isogenic background for use as a source of genetic markers. All strains have short conidiophores (csp A1), which makes them easy to handle on test plates. Genetic markers were combined step
