title: [Action of the steroid glycoside deltonin on the bacterial membranes of Micrococcus lysodeikticus].
abstract: A slight detergent-like effect of steroid glycoside deltonine from Dioscorea deltoidea on the bacterial membranes of Micrococcus lysodeikticus was detected which resulted in the breaking of the osmotic barrier of protoplasts and in the loss from the membranes of small fragments containing the dehydrogenases of the respiratory chain but without cytochromes. These small fragments still retained the membrane structure.
