Organic UV filters are common compounds in the aquatic environment. These chemicals are used as active substances in chemical formulations of personal care products, in order to protect the skin, lips and hair against solar UV radiation. Organic UV filters easily reach the aquatic environment by incompletely removal in
wastewater treatment plants and subsequent discharge of effluents into surface waters. These substances pose a threat to aquatic organisms because many of them exhibit hormonal activity. Benzophenone-3 (BP-3) is the most commonly used UV filter in cosmetic formulations worldwide. In surface waters in Romania, the concentration range detected for BP-3 ranged between 3-52 ng/L. Thus, degradation using bacterial strains can be a promising alternative to reduce the problems of environmental pollution with BP-3. Bacteria are a cost-effective alternative to catalytic processes. Finding suitable bacterial strains for BP-3 removal could improve the WWTP process by bioaugmentation. The aim of this study was the biodegradation of BP-3 in presence
of two bacterial strains, namely Salmonella typhymurium and Serratia rubidae.
