A total of ninety samples of domestic solid waste from five domestic waste dumpsites at Taiwo, Agbo Oba, Baboko, Unilorin and Tanke in Ilorin metropolis were collected over a six month period at two weeks interval, characterized and analyzed. Baboko has the highest mean waste composition of paper and cardboard with the lowest being from Tanke. Five fungal genera and five bacterial species were identified from the wastes. Food wastes have the highest percentage of 63.30% while wood has the lowest of 0.08%. Glass and paper had the highest mean percentage of non-combustible component of 99.98% each, while leather had the highest ash of 18.44%. Escherichia coli and Aspergillus niger had the highest occurrence in both the rainy and dry seasons of the bacterial isolate and fungal isolates respectively. Bacillus, Aspergillus and Mucor species were found to be the most widely distributed on all the wastes. Degradation was monitored through glucose production in enrichment media where Bacillus cereus was identified as the only bacterial isolate that can degrade paper while A. niger was found to be the most active degrader of the waste papers of the fungal isolate. All fungal isolate except Mucor mucedo and Rhizopus stolonifer were able to degrade waste papers to different degrees. In mixed culture, glucose production was highest with Aspergillus and Penicillium consortium. It is concluded that microorganisms present in domestic wastes could be used either singly or in consortium for waste degradation thereby proving to be a key to a clean and safe future world.
