Filtration-enrichment is a very successful method for obtaining auxotrophs, but traditional methods cannot be applied directly to many fungi lacking suitable asexual spores, mainly because of a heavy carry-over of parental nutrients into sexual spores. A procedure has been devised to apply filtration-enrichment to such fungi by using hyphal mutagenesis, crossing, germination of sexual spores, fragmentation of germination hyphae into small propagules, and then two cycles of filtration-enrichment in liquid minimal medium (LMM).
