Fig. 6From: Green fabrication of ZnO nanoparticles via spirulina platensis and its efficiency against biofilm forming pathogensEffect of varying concentrations (µg/ mL) of the green synthesized ZnO NPs on S. aureus and K. pneumoniae, results are expressed as mean ± SD after triplicate studies. The * and ** in the bars represent S.E. (* p < 0.05, ** p < 0.01)Back to article page
