Abstract

Bisphenol A (BPA) is the basic building block in the production of polycarbonates, epoxy resins, dental products and other materials. BPA enters the environment during the chemical production, transport, processing or inadequate disposal of the product containing it. Because of its toxicity, BPA has an adverse impact on human health as well as animal and plant life, and has to be removed from the environment. In this paper, the biodegradation of BPA took place in the aqueous solution containing bacterial cultures of Pseudomonas aeruginosa BSW, Pseudomonas putida and Streptomyces sp. isolated from the environment. Various factors affecting the BPA biodegradation process, such as pH value, temperature, and optical density of the mentioned cultures were tested. According to the obtained results, the best BPA biodegradation of 40% i.e. 50% was achieved at pH value of 7 and temperature of 35° C for all three tested microorganisms. At optical density of 0.3, 10% higher BPA biodegradation was achieved with cultures Pseudomonas aeruginosa BSW and Pseudomonas putida than at optical density of 0.2 whereas the use of the culture Streptomyces sp. resulted in the best biodegradation at optical density of 0.2.
