Synthesis and secretion of hemolysin by Escherichia coli.

Hemolytic Escherichia coli cells were found to synthesize and secrete significant amounts of hemolysin into a mineral salt-glucose medium containing hemoglobin. The release of de novo-synthesized hemolysin was stopped in the presence of energy metabolism inhibitors such as 2,4-dinitrophenol, sodium azide, or potassium cyanide, resulting in an accumulation… CONTINUE READING
