Abnormal Development Of Phialides In A Strain Of Aspergillus Niger

An Aspergillus niger mutant strain (hpp) produces an average of 4.1% of conidiophores with phialide proliferations. Increased frequency of proliferations could be induced on all studied strains by growth on potato dextrose agar. The characteristic is recessive and seems to be due to a pleiotropic effect of the mutation for olive conidia color. © 1985 Birkhäuser Verlag.41121598159
