Biodegradation of oily wastewater by pure culture of bacillus cereus

The discharges of oily wastewater to environment caused serious damages to human, animal and environment and bioremediation are an attractive alternative to chemical method for removal of hydrocarbon from industrial effluents. This study has demonstrated a very good biodegradation capability of oily...
