The WINOGRAD student experiment which will investigate differences between the growth of Winogradski columns in weightlessness and on Earth.
A Winogradski column is a colony of different types of bacteria in which the waste products of one bacterium serve as nutrients for another and vice versa. On Earth they live in pond or lake water and need only light for photosynthesis. This makes them of interest to scientists, who want to find out more about a possible future role for bacteria in long-duration spaceflight. Bacteria could help to dispose of waste or to recycle air and water, and their gas might be used as fuel.
