abstract={The role of urea and NPK 15:15:15 fertilisers as biostimulants of microbes in the bioremediation of domestic wastewater was investigated in this study. Five samples of domestic wastewater supplemented with 10, 20, 40, 60 and 80 g/L of urea, NPK as well as a combination of both fertilisers and the control were monitored for bioremediation. The indicating parameters such as pH, Biochemical Oxygen Demand (BOD), and Dissolved Oxygen (DO) over a period of 5 weeks were used. The results obtained showed that there was a BOD reduction of 86.62, 85.24 and 86.85% for wastewater treated with urea, NPK and a combination of both respectively. Stimulation by the fertilisers improved the DO level by 76, 75 and 77.8% respectively for wastewater treated with urea, NPK and a combination of both respectively. Generally, the best results were obtained when both fertilisers were used together. The final values of pH, BOD and DO fell within the values of 6-9, 30 mg/L and 2 mg/L set by the Federal Environmental Protection Agency (FEPA). The results obtained indicate the effective use of urea and NPK fertilisers in stimulating the activity of microbes for bioremediation in wastewater.},
