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.
