Aerobic biodegradation potential of proteobacteria mixed- culture consortium on inhibitory refinery effluent

The classical treatment approaches to recalcitrant and offensive petroleum refinery effluents is quite strenuous and defective, thus necessitated the modification of existing protocol for effective and conceivable degradation. The high COD content, presence of toxic substances such as phenol and hyd...
