Fig. 1From: Effects of various heavy metal nanoparticles on Enterococcus hirae and Escherichia coli growth and proton-coupled membrane transportThe effect of dioctyl sodium sulfosuccinate (DSS) alone and together with Ag nanoparticles on E. hirae ATCC9790 and E. coli K-12 lag phase duration. Control was bacterial growth without nanoparticles. Ag nanoparticles and DSS were diluted by 10, 20, 50, 100, 200 and 500 folds. For details see “Methods”Back to article page
