remediation technique that introduces natural hydrocarbon digesting bacteria and materials such as enzymes to remove hydrocarbons from soil, water or even air.

n: I. the process of breaking down organic wastes with microbes. Bacteria that are naturally present in the environment use microbial enzymes to break down die materials into a soluble form that passes through the cell walls of the bacteria. The bacteria metabolise d1e material and convert it into components d1at are more readily assimilated in d1e environment, such as water or carbon dioxide (i.e., a gardeners compost pile). 2. the creation of engineered and managed conditions to boost natural bioremediation processes. Nutrients are added to stimulate the bacteria naturally present in the waste. Oxygen ari1 pH levels are adjusted for maximum effectiveness, and, if conditions are right, the bacteria grow in large numbers and break down the hydrocarbons much more rapidly than with natural bioremediation. In cases in which the necessary bacteria are not already present in the waste, suppliers can provide diem along with die appropriate nutrients.

a protein based (non-living) material that can serve as a catalyst for many organic reactions.

n: a decomposition process of certain organic substances, such as starch, in which a chemical change is brought about by enzymes, bacteria, or other micro organisms. Often referred to as souring."

n: the process in which the microbes make organic substance decompose
