Abstract:

 The effects of cassava effluent on soil microbial and physicochemical properties were studied using culture-dependent andstandard analytical methods. Soil samples were collected from sites polluted with cassava effluent and from adjacent sitesthat were not impacted with the effluent pollution. The isolation and enumeration of microbial population was carried outusing standard culture-based methods. Standard analytical methods were used to assay for physicochemical properties. Thehighest bacterial count of 3.61×108 ± 0.12 CFU/g was recorded for polluted soil sampled from Ehor, while the lowestcount of 1.3×108 ± 0.03 CFU/g was recorded in Isihor. Isihor had the highest fungal count of 2.2 ×108 ± 0.01 CFU/g fromsoil contaminated with cassava effluent. The fungal counts of the polluted soil were significantly lower than the bacterialcounts generally (p < 0.05). The heavy metal contents of the contaminated soils were relatively higher than theuncontaminated soil (control). Unlike in the control soils, pH of the polluted soils ranged from 4.0 - 4.78. The bacteriaisolated were Bacillus subtilis, Bacillus macerans, Pseudomonas aeruginosa, Klebsiella aoxytoca and Escherichia coli.Eleven species of fungi belonging to the genera Aspergillus, Penicillium and Rhizopus were also isolated. The presentstudy shows that the cassava effluent can have an increasing or limiting effect on the microbial diversity of the polluted soilwhich could also be attributed to the simultaneous impact on the physicochemical parameters of the soil.
