[oxygen, pyridines, mechanical, CO₂, petroleum, fatal, polyester, norcadia]

Spilling of ______ oil occurs in ocean due to various reasons. This oil may prove ______ and toxic to aquatic organisms. It is not easy to remove the oil layer from surface of water by ______ method. However, bacteria like pseudomonas spp. and Alcanovorax borkumensis have to ability to destroy the ______ and other chemicals. Hence, these bacteria are used to clear the oil spills. These are called as hydrocarbonoclastic bacteria (HCB). HCB decompose the hydrocarbons and bring about the reaction of carbon with ______. ______ and water is formed in this process.

Answer 1

Spilling of petroleum oil occurs in ocean due to various reasons. This oil may prove fatal and toxic to aquatic organisms. It is not easy to remove the oil layer from surface of water by mechanical method. However, bacteria like pseudomonas spp. and Alcanovorax borkumensis have to ability to destroy the pyridines and other chemicals. Hence, these bacteria are used to clear the oil spills. These are called as hydrocarbonoclastic bacteria (HCB). HCB decompose the hydrocarbons and bring about the reaction of carbon with oxygen. CO₂ and water is formed in this process.
