Predominant Bacteria in Domestic Solid Waste Dump in Egbu Owerri North Local Government Area in Imo State, Nigeria

Abstract

The prevalence of bacteria in solid waste dump from domestic  waste in Owerri was studied. Six (6) samples were collected from Egbu community in Owerri North and examined bacteriologically using Nutrient agar and macconkey agar and were serially diluted, cultured, identified and characterized. Five genera of bacteria were isolated. They are Staphylococcus aurous, Klebsiella sp, Escherichia coli, lactobacillus sp and Corynebacterium sp and from the findings, Klebsiella exhibited the highest (66.6%) number of bacterial activity while Corynebacterium and Iactobacillus exhibited the lowest (16.67%). Futhermore, location D has the highest total hetertropic bacterial count of 5.75x 10⁸ and the least is location E with 6.25x10⁷. T he presence of Escherichia coli, Staphylococcus aureus, Cornebacteria and Klebsiella in the waste dump site is an indication that the contamination is of human and plant orign or their activities.
