Figure 4From: Antimicrobial activities of commercial nanoparticles against an environmental soil microbe, Pseudomonas putida KT2440Response of the P putida KT2440 biosensor to combinations of nano-Ag, nano-CuO and nano-ZnO at defined doses of mg Ag/L and mg Cu/L. Changes in Lux output (Relative light units RLU) and cell culturability (colony forming units Cfu) are shown. Studies were performed as described in Methods. NCD = No culturable cells detected. Data are from one study typical of at least three generated under the same conditions. Means and standard errors are shown.Back to article page
