Factory waste, printing and dying industry waste, and bio-organic waste and now oil spills all require bacteria or complex of microbes to clean them as bacteria can utilize these products for their nutrient requirement. Bacteria may not be able to degrade these products completely but they can bring them to a stage where they are easily disposed.
Its time more time and research is done on bioremediation
If we could have enough information how to cure the oil spills with bacterial treatments it will save future disasters.
Its time we undertake bioremediation as serious research topic.
