The concept of microbial integration was carried out to examine bacterial and fungal activity on bezene, toluence and xylene (BTX) degradation in a batch reactor. The investigation was conducted for thirty five day of exposure of contact of members and substrate which yielded enzyme substrate complex as well disintegrated to produce products and free enzyme. Bacterial and fungal concentration was monitored per week and the results obtained recorded. The gas chromatography results of Ngara soil sample investigated reveals the concentration of M, P, and O – Xylene for different days of exposure. Increase in both bacterial and fungal was experienced with decrease in BTX concentration, whereas increase in bacterial is more than fungi, indicating the high activity of bacterial in the reactor than that of fungi. Although, both were well integrated in bioremediation program to enhance the effective remediation of BTX contaminants in Ngara soil, Omuigwe Alun Community, Niger Delta Area of Nigeria.
