GENERAL HISTOLOGY

Detailed explanation-1: -Bacteria can break down oil to carbon dioxide and water. However, no single organism can break down all the components of crude oil or refined fuels spilled into the environment. The tens of thousands of different compounds that make up oil can only be biodegraded by communities of microorganisms acting in concert.

Detailed explanation-2: -Pseudomonas putida also called as oil guzzlers is a gram negative, rod shaped, saprophytic bacterium which was patented by Ananda Mohan Chakrabarty, for the ability of the bacterium to biodegrade oil.

Detailed explanation-3: -After a disastrous deep-sea oil spill, a bacteria was discovered at great ocean depths, feasting on the oil. Now known as Alcanivorax borkumensis, the bacteria was able to digest oil by breaking down petroleum hydrocarbons with the use of special enzymes-something no other known bacteria can do.

Detailed explanation-4: -False : Bacteria used to clear oil spills are called Hydrocarbonoclastic bacteria (HCB).

Detailed explanation-5: -1. Dispersion: Chemical dispersion is achieved by applying chemicals designed to remove oil from the water surface by breaking the oil into small droplets. 2. Burning: Also referred to as “in situ burning, ” this is the method of setting fire to freshly spilled oil, usually while still floating on the water surface.
