Abstract

Under aerobic conditions, thioglycerol, dithiothreitol and cysteine stimulated stationaryphase Escherichia coli to secrete riboflavin. Thioglycerol also enhanced the secretion of porphyrins and unidentified yellow pigments. Under anaerobic conditions, thiols failed to stimulate riboflavin secretion, but 5 out of 8 thiols tested caused increased porphyrin excretion. Secretion of these substances is a manifestation of the pleiotropic response of E. coli to reductive stress.
