Aerobic Bioremediation of Brewery Effluent using Escherichia coli and Pseudomonas sp.

Effluent from Guinness Nig. Plc was obtained and inoculated with two aerobic organisms, and physicochemical analysis was carried out to evaluate the intrinsic degradative capabilities of the organisms based on the parameters to determine which organism has a better degradative potential for the effluent. This study used two bacterial species, Escherichia coli and Pseudomonas sp. The study was divided into two setups for each microorganism, and the third was set up as a consortium of the two. The study showed a reduction in biological oxygen demand (BOD) and a simultaneous reduction in the inorganic nutrient content of the effluent, such as phosphate, nitrate and sulphate, which were believed to be utilized for the growth of their biomass. This study confirms the potentials of the test organisms to mineralize brewery effluent in the presence of oxygen which is an environmental friendly and cost effective approach to effluent management.
