Biodeterioration Potentials of Microorganisms Isolated from Pig Manure Obtained at Awka, Nigeria

Abstract The biodeterioration potentials of microorganisms isolated from pig manure was studied using standard methods. resinae and the bacterial and fungal consortia that produced the highest turbidity and clarity indicating hydrocarbon utilization. The growth profile of Micrococcus luteus, Pseudomonas aeruginosa, Aspergillus niger and Cladosporium resinae as well as the fungal and bacterial consortia during 35 days of growth in mineral salts-oil medium showed that there was a decrease in the pH and an increase in the viable count of the medium. The highest percentage degradation of the crude oil was by the bacterial consortium (62.0%). This work showed that Pig manure which is generally regarded as a waste product harbours diverse bacteria and fungi which will be useful in remediating oil-polluted environments when applied singly and as a consortia
