ISOLATION AND IDENTIFICATION OF MICRORGANISM FROM DIESEL AND PETROL CONTAMINATED SOIL

A biological treatment was used to determine the potential microbes to degrade the pollutants. The present study was designed to identify microorganism present in the agricultural contaminated petrol and diesel treated soil sample and study their degradation. The identified Colonies subjected to biochemical test revealed that they were Acinetobacter baumamii, Azotobacter tropicalis, Bacillus subtilis, Corynebacterium variabilis, Flavobacterium lutescens, Micrococcus luteus, Plesiomonas shigelloides, Pseudomonas fluorescens and Xanthomonas oryzae. The pH of the petrol and diesel was increased as the degradation percentage increased. Petrol contaminated soil has degradation percentage of 34.89%. The diesel contaminated has degradation percentage of 23.46%.
