Biotechnology in the Environment


In the 1980's, scientists began to look for ways to use micro-organisms to break down the complex compounds in toxic waste. This process is called bioremediation. Different species of bacteria and fungi can decompose or break down almost anything -- including chemicals that are toxic to humans. In many cases, the breakdown of complex compounds requires a group of different organisms called a consortia.

Oil Spill Bioremediation

Scientists are increasingly using bacteria to break down spilled oil. Few bacteria are capable of using oil as a nutrient. Bacteria are found in almost all soils, but the types of bacteria vary with the soil conditions.

Science Inquiry

Predict, in your Science Log, where you would find soil that contains bacteria capable of breaking down oil. Why do you think the bacteria are found there? Scientists, using bacteria to break down oil, often spray fertilizer on the mixture of bacteria and oil. Why do you think they do this?
