fish or bacteria?

Randall von Wedel has changed over from studying medicine to studying the environment. He was very discouraged by the deterioration of our environment. So Randall decided to research natural bacteria (bioremediation), effective solvents that are derived from vegetable oils (biosolvents), and a clean burning fuel made from nontoxic renewable vegatable oils and recycled cooking oils (biodiesel). He states that we all have connections to the earth and all do our part in poluting it. This I totally agree with, whether we mean to or not. "Industrial biotreatmant plants are basically bioremediation systems using living bacteria to process polluted water in ponds and tanks." We just needed to do tests to see which were biodegradable and which ones can break down these complicated materials. He started in a lab and tried to acclimate the bacteria to the point that it will use the toxic material as a source of food, as energy and as a source of carbon dioxide and water. He later creates a bacterial aquarium, with 5 gallon tanks and then larger drums. His end result was, he could clean up oil spills by installing this process. So this would be used for gas stations, shopping malls, truck terminals. They would interupt the flow of water where the oil, gas or diesel concentrates, then process the water in an above ground reactor. It would need to be treated over a period of about twelve to fifteen hours until the water comes out clean. The concept of all bioremediation is the same: you're letting bacteria eat something that has energy. They use the energy to grow and we get back clean water.
