摘要：

Cytochromes c3 from D. vulgaris (Hildenborough strain) and D. desulfuricans (Norway strain) were studied by differential pulse polarography and spectroelectrochemical method. Both cytochromes exhibit 2 reduction potential values Eh .apprxeq. -0.25 and -0.34 V (D. vulgaris), Eh .apprxeq. -0.16 and -0.34 V (D. desulfuricans). Titrations by dithionite and controlled potential electrolysis coupled with polarography and spectrophotometry suggest that in both cases electronic exchanges are rapid.
