The effect of cassava effluent on soil microbial were studied soil. Sample were collected from sites pollutes with cassava effluent and from adjacent sites that were not impacted with the effluent pollution. The isolation and enumeration of microbial population was carried out using standard culture. The highest bacterial count 2.9 x 106 – 3.7×106 cfulg was recorded for polluted soil sample while the lower count of 4.4 x 106 – 4.6×106 cfulg was recorded in the control soil. Also there was higher record of fungal frequency occurrence in cassava effluent polluted soil (5 – 10) while that of control was (2 – 3). The bacterial load of the contaminated soil was seen to be higher than that of the fungal load. The bacteria isolated were Micrococuss sp., Bacillus sp.and Pseudomonas aeruginosa in cassava effluent polluted soil while in the control were pseudomonas aeruginosa, Staphylococcus sp., Bacillus sp. and Aerococcus sp. Four (4) species of fungi belonging to the genera Aspergillus, peniciuium and sacharomyces were also isolated. The present study show that the cassava effluent can have an increasing or effect on the microbial diversity of the polluted soil.
