Abstract: Many research studies have revealed that materials like heavy metals have bacteriostatic and fungicidal properties. Copper and some heavy metals alloy surfaces can inhibit the growth of microorganisms. Our present study was focused on studying the fungal growth inhibitory properties of heavy metals. Heavy metals tested (Copper, Zinc and Magnesium) by surface contact method could inhibit the growth of Aspergillus niger, a common fungus involved in food contamination. This study helps in identifying antifungal heavy metal materials. These metals can be used for water storage and cooking purpose which can reduce the food contamination by fungi. By the usage of antimicrobial materials for the purpose of water supply systems, Air conditioning systems, Surfaces, Door knobs etc. fungal infections in hospitals, laboratories and in our homes can be reduced.
