Effluent from industries contains physical, chemical and biological pollutants which can occur from anthropogenic activities. This study investigated the microorganisms present in effluent from palm oil mill and to know the impact of Electromagnetic field (EMF) treatment on bacterial population and physicochemical characteristics of palm oil mill effluent. Microbiological investigation on effluent was carried out using standard methods. Collection of samples were done from palm oil mill in Ipetu Ijesa. Bacteria isolated from industrial effluent samples during raining season were Bacillus cereus, Bacillus subtilis, Enterobacter aerogenes, Enterococcus faecalis, Klebsiella oxytoca, Lactococcus lactis, Micrococcus luteus, Salmonella typhi, Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus saprophyticus, Shigella flexneri, Streptococcus viridians and Pseudomonas aeruginosa. The fungi isolated were Aspergillus niger, Aspergillus flavus, Aspergillus fumigates, Fusarium culmorum, Rhizopus stolonifer and Saccharomyces cerevisiae had the highest bacterial load 2.45×104cfu/ml and Cassava processing plant had lowest bacterial load 1.78×104 cfu/ml. Bacillus cereus was the dominant bacterial specie while Aspergillus flavus was the dominant fungal specie. Palm oil mill effluent had the highest mean for colour (19.15Pt/co), pH value (10.48), temperature (27.33°C), conductivity (240mS/cm) total soluble solids (322 mg/l) total hardness (251mg/l). Effluent from the brewery had highest value for iron (3.67±0.02). Therefore, from the study the effluents from all industries had high microbial load and physicochemical parameters that exceeded the tolerable levels set by WHO standards. The availability of some isolates and toxic substances can serve as of populace inhabiting these places.
