Rensselaer researchers to send bacteria into orbit aboard space shuttle Atlantis
Date:5/10/2010

Troy, N.Y. A team of researchers from Rensselaer Polytechnic Institute will send an army of microorganisms into space this week, to investigate new ways of preventing the formation and spread of biofilms, or clusters of bacteria, that could pose a threat to the health of astronauts.

The Micro-2 experiment, led by Cynthia Collins, assistant professor in the Department of Chemical and Biological Engineering at Rensselaer, is scheduled to launch into orbit on May 14 aboard Space Shuttle Atlantis. The microorganisms will spend a week in space before returning to Earth aboard the shuttle. Within just a few hours after the shuttle's return, Collins will be able to examine the bacteria and resulting biofilms to see how their growth and development were impacted by microgravity. The samples also will be returned to Rensselaer, to be examined using the core facilities of the Institute's Center for Biotechnology and Interdisciplinary Studies.

"We know that gravity plays a key role in the development of biological systems, but we don't know exactly how a lack of gravity affects the development of bacteria and biofilms," Collins said. "This means while certain bacteria may be harmless on Earth, they could pose a health threat to astronauts on the International Space Station or, one day, long space flights. Our goal is to better understand how microgravity affects the relationship between humans and bacteria, so we can develop new ways of reduce the threat of biofilms to spacecraft and their crew."

Partnering with Collins on the Micro-2 project are nanobiotechnology expert Jonathan Dordick, the Howard P. Isermann Professor of Chemical and Biological Engineering at Rensselaer and director of the university's Center for Biotechnology and Interdisciplinary Studies, and thin films expert Joel Plawsky, professor in the Department of Chemical and Biological Engineering. NASA is funding the experiment.

Biofilms are complex, three-dimensio
