Growth of C. perfringens strain 13 in the presence of various sulfur sources. Growth curves of strain 13 grown in a sulfur-free minimal medium in the presence of 1 mM sulfite (■), 1 mM glutathione (□), 0.5 mM cystine (●), 1 mM homocysteine (○), 1 mM methionine (▲) or in the absence of any sulfur source (△). We observed a similar growth for homocysteine and cystathionine, thiosulfate and cystine or sulfide and sulfite.
