Quantitative analysis of gram positive and gram negative bacteria exposed to various concentrations of nanocomposites. a log cfu/ml of surviving Escherichia coli upon exposure to peptide and nanocomposites. b Quantification of Salmonella Typhimurium upon exposure to peptide and nanocomposites. c Staphylococcus aureus exposed to various nanocomposites. d Quantitative analysis of Streptococcus pyogenes. Bacteria were grown in LB broth containing various concentrations of nanocomposites and all the cultures were incubated at 37 °C with shaking at 250 rpm and the cfu/ml counts were done at 24 h. Statistical differences were indicates as * when p ≤ 0.05, or ** when value was p ≤ 0.01. Error bars represent standard deviations determined from at least four replicates
