Fig. 4From: Microbial synthesis of zinc oxide nanoparticles and their potential application as an antimicrobial agent and a feed supplement in animal industry: a reviewStrategies for optimizing the synthesis of ZnO NPs. The synthesis of NPs is associated with different physicochemical parameters including pH, temperature, precursor concentration, microbe age, reaction times, irradiation, and stirring. Each of these parameters contributes to variations in size, shape, monodispersity, and yield of NPsBack to article page
