PORTER Department of Bacteriology, College of Medicine, The State University of Iowa, Iowa City, Iowa Received for publication July 31, 1950 The microbial degradation of cystine and cysteine was first quantitatively investigated by Tarr (1933), who concluded after using Proteus vulgaris that cystine is reduced to cysteine, the latter then being anaerobically dissimilated to acetate, formate, hydrogen sulfide, and ammonia. Desnuelle and Fromageot in a series of studies (Desnuelle and Fromageot, 1939; Desnuelle, 1939; Desnuelle et al., 1940) observed a system in Escherichia coli and Proprionibacterium pentosaceum that liberated hydrogen sulfide and ammonia from cysteine.
