Reversion of an acetate requiring strain and the induction of sectored colonies are used to establish optimal conditions for nitrosoguanidine and ultraviolet light mutagenesis in Eudorina elegans Ehrenberg. Nitrosoguanidine is more effective in causing reversion of the acetate requiring strain and inducing auxotrophs. Morphogenetic mutants are more readily induced by ultraviolet light. The effectiveness of ultraviolet light as a mutagen is cell cycle dependent whereas the mutagenic action of nitrosoguanidine is not.
