Wastewater contains a wide range of pollutants that must be treated before discharge. Bioremediation represents an environmentally friendly solution, as it relies on naturally occurring processes without the emission of harmful substances or the use of chemicals. This process is carried out with the help of microorganisms, which, through their metabolic capabilities, degrade or transform toxic pollutants into less toxic forms. The use of microorganisms in bioremediation plays a key role in maintaining and preserving ecological balance.[1] The main techniques applied in bioremediation are bioaugmentation and biostimulation. Their application enhances the efficiency of wastewater treatment while supporting sustainable environmental practices. In this study, bioremediation of wastewater from biowaste was carried out using the biostimulation technique under batch, submerged, and aerobic conditions at 25±1°C over 5 days. The chemical oxygen demand (COD), pH value and dissolved oxygen concentration (DO) were determined in the experiment. The results showed a 57% reduction in COD and a 46% reduction in DO concentration, indicating increased microbial activity. The obtained pH values were in the neutral to slightly alkaline range. Bioremediation is considered a modern and effective approach to remediating contaminated areas because it uses biological processes to break down and remove pollutants from the environment.
