Abstract

Summary: Mutants of , Wisconsin strain 72–4, were produced by multiple X-ray and ultraviolet irradiation. The mutants differed from the parent strain culturally and in citric acid production. Comparison between the yields of citric acid from the parent strain and mutants showed significant increases with the latter. In crude sugar media, such as ferrocyanide-treated brown sugar, yields of citric acid equivalent to 80% of the sugar fermented were obtained in aerated culture, whereas only 21% was obtained with the parent strain.
