abstract={The microbiological and physicochemical characteristics of soil receiving cassava effluent in Elele Rivers State, Nigeria were carried out. A total of twenty four (24) samples were collected and analysed microbiologically for total aerobic bacterial plate count, coliform count, <i>Escherichia coli</i> count and fungal count using pour plate technique. The media used were nutrient agar, MacConkey agar, eosin methylene blue agar, Sabouraud dextrose agar. The T-test was used to test for significant difference. The mean total aerobic plate count of contaminated soil ranged from 5.76 ¡À 0.05 log<SUB>10</SUB>cfu/g to 5.60 ¡À 0.11 log<SUB>10</SUB>cfu/g, coliform count of contaminated soil ranged from 4.71 ¡À 0.07 log<SUB>10</SUB>cfu/g to 4.56 ¡À 0.08 log<SUB>10</SUB>cfu/g, <i>Escherichia coli</i> count of contaminated soil ranged from 2.56 ¡À 0.06 log<SUB>10</SUB>cfu/g to 2.39 ¡À 0.11 log<SUB>10</SUB>cfu/g, fungal count of contaminated soil ranged from 3.65 ¡À 0.09 log<SUB>10</SUB>cfu/g to 3.47 ¡À 0.09 log<SUB>10</SUB>cfu/g. The control sample has the following values for total aerobic plate count 5.84 ¡À 0.07 log<SUB>10</SUB>cfu/g, Coliform count of 4.28 ¡À 0.11 log<SUB>10</SUB>cfu/g, fungal count of 3.19 ¡À 0.16 log<SUB>10</SUB>cfu/g and <i>Escherichia coli </i>count of 2.14 ¡À 0.12 log<SUB>10</SUB>cfu/g. Microorganisms isolated were: <i>Klebsiella</i> species, <i>Staphylococcus aureus, Escherichia coli</i>, <i>Pseudomonas </i>species, <i>Enterobacter </i>species<i>, Bacillus </i>species, <i>Proteus </i>species, <i>Aspergillus </i>species, <i>Rhizopus </i>species and <i>Penicillium </i>species. Soil contaminated with cassava effluent caused some physicochemical changes in the samples collected which were: Cyanide content 3.0 mg/kg, conductivity 33.4uS/cm, phosphate 0.52 mg/kg, nitrate 0.35 mg/kg, sulphate 13.0 mg/kg, calcium 167.0 mg/kg, pH 6.3 mg/kg, magnesium 89.0 mg/kg, potassium 4.0 mg/kg and sodium 92.0 mg/kg. The cassava effluent should therefore be treated before discharge into the environment to prevent possible pollution.},
