Food is one of the basic commodities for the survival of life to the living beings which, in turn, makes its safety issues more important. On global platform, issues related to food safety are taken as very seriously due to its ill effects on public health. According to the data available to World Health Organization (WHO), more than two billion people fall sick due to the consumption of spoiled food.Currently, food products such as meat, dairy products, fruits, and bakery products got contaminated due to the presence of spoilage microorganisms such as bacteria, fungi, and other contaminants.The common bacterial species, which are responsible for the spoilage and wastage of food products, such as fruits, vegetables,

Highlights Potential involvements of microbial laccases in the synthesis of silver and gold nanoparticles have been comprehensively assessed. Treasured roles of microbes and associated enzymes in synthesis of gold and silver nanoparticles have also been presented. As potential green biocatalysts for the synthesis of metal nanoparticles, microbial laccases may be promisingly used. Methodologies as well as involved possible mechanisms have been discussed in details in order to disclose the effectiveness of microbial laccases in the synthesis of gold and silver nanoparticles. Different characterization results of synthesized gold and silver nanoparticles based on UV–Vis spectra, XRD, SEM, TEM and other techniques have also been discussed. Mechanistic evaluation also shows a hope for the effectiveness of microbial laccases in the synthesis of other metal nanoparticles.
