Scenedesmus obliquus, grown under culture conditions which led to unicell populations, was treated with N-methyl-N'-nitro-N-nitrosoguanidine and then cells were plated on rich medium to recover auxotrophic mutants. Carbon source and vitamin (p-aminobenzoic acid, thiamin and nicotinamide)-requiring mutants were characterized. Amino acid-requiring mutants, some of types not previously isolated from green eukaryotes, were also obtained: 11 had a requirement for arginine, one for valine, two for threonine or isoleucine, and one for tryptophan, tyrosine or phenylalanine. The possible metabolic blocks of these amino acid-requiring mutants are discussed.
