Bioremediation v.s. Biodegradation
Biodegradation refers to the natural process whereby bacteria or other microorganisms alter and break down organic molecules into other substances, such as fatty acids and carbon dioxide.
Bioremediation is the act of adding materials to contaminated environments, such as oil spill sites, to cause an acceleration of the natural biodegradation process.
Fertilization is the bioremediation method of adding nutrients, such as nitrogen and phosphorus, to a contaminated environment to stimulate the growth of indigenous microorganisms. This approach is also termed nutrient enrichment. Seeding refers to the addition of microorganisms to a spill site. Such microorganisms may or may not be accompanied by nutrients. Current seeding efforts use naturally occurring microorganisms.
