Fairport High School
Recently, the ISS has encountered difficulty with metal-eating bacteria which have caused the hull of the station to decay. UV radiation is currently employed by ISS personnel to destroy bacteria on the hull. The proposed experiment will determine the effectiveness of UV radiation in removing the bacteria. We will study the effect of altered gravity levels on the effectiveness of using UV radiation to eliminate bacterial colonies.The luminescence of the bacteria will be linked to the production of ATP; we will consider bacteria that are no longer producing ATP to be dead. The change in luminescence of the bacteria will show the death rate. A photocell will be used to measure the change in the luminescence of the bacterial colony after it has been exposed to the UV radiation. The luminescence can be monitored with a camera and a photocell. If the rate at which the decreasing luminescence changes, then we can see if the rate of death of the bacteria is affected by altered gravity.
