RELATIONSHIP BETWEEN MORPHOLOGICAL DIFFERENTIATION AND EXTRACELLULAR ENZYME FORMATION IN ASPERGILLUS NIDULANS

[摘要] Intra- and extra-cellular activities of protease, nuclease, and invertase were examined with four newly isolated morphological mutants of Aspergillus nidulans. As far as the four mutants subjected to the investigation were concerned, extracellular activities of these enzymes were markedly changed. Some relationship between morphological mutation and extracellular enzyme formation was assumed and this assumption was supported genetically with two mutants which gave rise to wild-type revertants.
