Biodegradation of petroleum oil achieved by bacteria and nematodes in contaminated water

► Microbes can recycle petroleum contamination and remove our health and environment risk. ► Biological treatment is the best method of choice for it is safe and cost effective. ► Bacteria and nematodes give a synergistic effect to bioremediate the contamination. ► Nematodes from a sewage plant can survive in concentrated diesel contaminated water. ► Commercial oil/water interface meter can be applied routinely for the bioremediation.
