Better understanding of microbial synthesis method especially viral mediated synthesis including TMV-bio template synthesis of AgNPs is needed as it is used to synthesize 1-D silver nanoparticles . These 1-D AgNPs owing to their larger surface area enhances the adsorption and catalytic reduction of phenol . Although other microbial methods such as fungi , bacteriogenic and algae-mediated synthesis of AgNPs can be slow and time-consuming process affecting its scalability, it uses non-hazardous reagents which can produce non-toxic biodegradable AgNPs that can reduce phenolic contamination in waste water without having adverse effects on human health and environment. However, more studies should be conducted to increase the scalability, stability and enhance the cost and time reduction of plant and microbial mediated synthesis silver nanoparticles.
