Abstract
Due to its extensive production and use in industrial activities, phenol is a significant environmental contaminant in most wastewater facilities, including those at oil refineries, coking plants, pharmaceutical, and plastic sectors. In situations where phenol pollutants are present, many aquatic creatures, including microbes, plants, and fish, represent a risk of mutagenic, teratogenic, and carcinogenic consequences. As a result, the U.S. Environmental Protection Agency has identified phenol as a highly dangerous chemical and added it to its list of priority pollutants. Therefore, this study was focused on biologically degrading phenolic chemicals in water by microbial enzymatic activity. In this experiment, seven water samples from various locations in El-Gharbya Governorate, Tanta, Egypt, were taken for this study, effluent from car repair shops, influent from water treatment plant, influent from wastewater treatment plant, effluent from wastewater treatment plant, cooling effluent from petrochemical company, effluent from restaurants, and effluent from car washes.
