Résumé :

The effects of β-mercaptoethanol, a reducing substance with a -SH group, on the growth and redox potential of bacterial and yeast cultures, have been studied. Both substances inhibited cell division in these microorganisms, but this action does not appear to be due to any change in the redox potential of the culture medium. The reduction of dithiodiglycol to mercaptoethanol in the presence of bacteria and yeasts can be attributed to the action of a disulfide reductase identified in yeasts by Thompson. The respiratory process does not appear to be the essential target of mercaptoethanol inhibition, since the latter occurs whether the yeast cells are able to respire or not. The significance of these results is discussed. © 1963.
