2.1.1.8 The process of biodegradation:
The microorganisms can degrade 0.03 - 0.5g of oil / day per square meter. When oil falls into the water, microorganisms activity. Diffusion process occurs well, the strong eat the oil also occurs. Conditions of oil eating micro-organisms can grow is to have oxygen. Therefore, in the surface oil susceptible microbial degradation, even when sinking to the bottom, it is difficult disintegrated in this way.
Because the oil eating microorganisms exist largely in water biodegradation process of oil pollution occurs primarily at the contact surface between oil and water. Therefore, the process of natural dispersion of oil contaminated with oil into small particles in the water column increases the biodegradation process by about 10-100 times the area exposed by the oil - water rose. It was for this reason that oil pollution on land and in the sand often biodegradable much slower.
