Bacteria Name: Deinococcus radiodurans Pronunciation: Dee-no-coch-us radio-dur-ans Abbreviation: D. radiodurans Bacteria Raw Materials Environments: Soils, fresh water, extreme temperatures ( C), dry environments but not salts or salt water Applications: Radioactive Waste, Heavy Metals and Mercury D. radiodurans No Mobility D. radiodurans Capsule resists heat, cold, light, radiation, but not salts D. radiodurans No special Genetic features D. radiodurans Energy from organic and some inorganic chemicals D. radiodurans Reproduction is rapid and in extreme environments D. radiodurans Has no Pathology, not disease causing D. radiodurans Cell Membrane resists dehydration & chemicals

Narrative: We have a crisis that could make or break a small business in rural Colorado. A small-scale processor of organic foods has found pesticides, specifically Atrazine, in a shipment of soybeans they have already started to process! Their grinding equipment needs to be cleaned up fast so they can get back to work but they cannot just wash the atrazine down the drain. The grinders they used are in a very cold warehouse and have a lot of ‘nooks and crannies” so they need a mobile organism, but not one that can ‘get away’. Most importantly, we have to guarantee that the organism will not stick around after the treatment, cause diseases, or get into the food system! Design Challenge #1

Design Considerations and Environment: Grinding equipment is contaminated with Atrazine (an oil-based pesticide) They need limited mobility to get into the small spaces, but not one that can get away! The warehouse is very cold and has bright lights (high UV light) The soybeans left behind organic chemicals and Nitrogen compounds The organisms need to be able to get their energy from organic compounds Organisms must NOT be able to survive, even for a day, after treatment The organisms cannot cause diseases in people

3-E Engineering Effective: Will the proposed solution work well and does it meet ALL of the proposed design specifications? Economic: Is the proposed solution done in a way that maximizes product efficiency and return on investment? Ethical: Can the proposed solution cause any harm to people or systems in the long and short term?
