Question

How can the oil spills of rivers and oceans be cleaned?

Answer 1

1. The oil spills in rivers or oceans are caused by crude oil or petroleum hydrocarbons.
2. This crude oil is highly toxic to aquatic flora and fauna.
3. By using mechanical means, the oil spill can be removed, but this is very difficult.
4. The biological way to remove this pollution is to use a culture of microbes such as Pseudomonas spp. and Alcanovorax borkumensis.
5. They can destroy the pyridines and other chemicals present in hydrocarbons.
6. These bacteria are called hydrocarbono-clastic bacteria (HCB), and they break down fuels by combining carbon and oxygen.
7. During the process, water and CO₂ are made. The oil spills are cleaned up by letting out HCB at the site of the spill.
