Cells of Vibrio cholerae underwent rapid autolysis when suspended in media of low osmolarity under non-growing conditions. Chaotropes like urea and guanidine. HCl which are potent protein denaturants caused complete and immediate lysis of whole cells. This unique sensitivity of V. cholerae to protein denaturants led to the development of a rapid method for the selective isolation of the outer membrane upon treatment of whole cells with urea. The composition of the outer membrane isolated from… CONTINUE READING
