摘要：Bisphenol A (BPA) is a chemical used to make polycarbonate plastics, epoxy resins, thermal paper. BPA-based products also include DVDs, computers, home appliances, spectacles and optical lenses, reusable water bottles, food storage containers, sports safety equip ment, medical equipment, construction materials, paints and coatings. BPA contamination may occur from many different sources, but the most common way of BPA contamination is through packaged foods or beverages where the packing material contains BPA. The objective of this research paper is to evaluate the antimicrobial activity of Bisphenol A (4,4'-Isopropylidenebisphenol) against fo ur different strains of bacteria i.e., Staphylococcus aureus, Bacillus substilis, Proteus valgaris and Escherichia coli, using agar diffusion method. BPA is completely soluble in organic solvents and partially soluble in water. The results showed the zone of inhibition in Staphylococcus aureus 23 mm, Bacillus substilis 22mm, Proteus vulgaris 21mm and Escherichia coli 20mm. From the results it can be concluded that BPA may show the cytotoxic effects and these studies are also under way.
