Growth Results for Microbes Collected by Citizen Scientists and Grown on the International Space Station

“Encouraging” for Long-Term Manned Spaceflight

Do microbes grow differently on the International Space Station than they do on Earth? Results from the growth of microbes collected by SciStarter’s community of citizen scientists in Project MERCCURI indicate that most behave similarly in both places.

“While this data is extremely preliminary, it is potentially encouraging for long-term manned spaceflight,” said Dr. David Coil, Project Scientist in the Microbiology Lab of Jonathan Eisen at the University of California at Davis. “With this part of Project MERCCURI we hoped to shed light on how microbes associated with the normal, human and built environment behaved in space. Our focus was not on microbes that cause disease, but the many beneficial and neutral microbes that surround us on a daily basis.”

SciStarter and the Science Cheerleaders organized a community of thousands of people across the country to participate in the citizen science portion of the project, gathering samples from built environments such as chairs, doors, railings… even the Liberty Bell. Then the “microbiology team” in the laboratory at UC Davis grew up and examined hundreds of microbes. The team selected 48 microbes, which, with approval from NASA, rode the SpaceX Falcon 9 to the Space Station for further research. Of those 48, only a handful grew at all differently in Space, and the difference was significant for only one: Bacillus safensis. This microbe was collected on a Mars Exploration Rover (before it was launched) at the NASA Jet Propulsion Laboratory in Southern California. It grew significantly better on the Space Station.

“We observed that the vast majority of the microbes we examined behaved the same on the Space Station as they do on Earth. In the few cases where we observed a microbe behaving differently in space than on Earth, we’d love to follow that up with further experiments,” said Dr. Coil.

In addition to comparing growth rates on Earth and the Space Station, UC Davis identified winners in three different categories for the “Microbial Playoffs” in space.

Best Huddle: the microbe that grew to the highest density, packing cells into the space allowed

  • Yuri’s Night, Los Angeles: Kocuria rhizophila was collected on a camera at a Yuri’s Night Party with Buzz Aldrin (the second person to walk on the moon).
  • San Antonio Spurs: Kocuria kristinae was collected on the court after a San Antonio Spurs game.
  • Discover Magazine: Micrococcus yunnanensis, collected from a dictionary at the offices of Discover Magazine.

Best Tipoff: the microbial competitor that took off growing like crazy from the start

  • Pop Warner Chittenango: Bacillus pumilus was collected on a Porta-Potty handle by Pop Warner Chittenango Bears cheerleaders.
  • Smithsonian Air & Space Museum: Pantoea eucrina was collected on the Mercury Orbitor at the Smithsonian Museum of Air and Space.
  • Pop Warner Saints: Bacillus horikoshii was collected on a football field by Pop Warner Saints cheerleaders from Port Reading, NJ.

Best Sprint: the microbe that grew the fastest during the sprinting portion of growth (technically known as the “exponential growth phase”)

  • Oakland Raiders: Bacillus aryabhatti was collected on a practice football field used by the Oakland Raiders.
  • Pop Warner Chittenango: Bacillus pumilus was collected on a Porta-Potty handle by Pop Warner Chittenango Bears cheerleaders.
  • Mars Exploration Rover (JPL): Paenibacillus elgii, collected from a Mars Exploration Rover before launch (2004) at the Jet Propulsion Laboratory (JPL- NASA, Pasadena, CA).

Find rankings of all 48 samples in these three growth categories on the Results page at the Space Microbes web site.

Other elements of Project MERCCURI are still in process. In addition to overseeing the microbial playoffs, astronauts also collected microbes on the Space Station and sent those back to Earth. The UC Davis team has analyzed the data from those and are preparing a scientific publication on the results. In addition, members of the public contributed 3,000 cell phone and shoe samples for an ongoing analysis of which microbes live where, and how that compares to the ISS.

“With this project, thousands of people contributed to research on the Space Station and at UC Davis, one of the leading microbiology research labs in the country,” said Darlene Cavalier, Founder of SciStarter and Science Cheerleader, which led the microbe collection effort. “Our goal is to spur even more people to get involved in significant science. Whether someone is a child or an adult, is interested in space or the ocean, in biology or chemistry, in the climate or computers – scientists are working on research and development that would benefit from more participation.” Learn about and sign up to help with more research projects at www.SciStarter.com .

Project MERCCURI is coordinated by Science Cheerleader (current and former NFL and NBA cheerleaders pursuing science and technology careers), SciStarter, and UC Davis, in conjunction with the Argonne National Laboratory. The Project is made possible by Space Florida, NanoRacks, and the Alfred P. Sloan Foundation.

 

 

Making Medicines from Soil: Going Behind the Scenes of a Citizen Science Project

Taking you behind the scenes and into the laboratory of the Citizen Science Soil Collection Program

This is a guest post by Dr Robert H. Cichewicz a professor at the University of Oklahoma and leader of the Citizen Science Soil Collection Program. Dr Cichewicz previously wrote on SciStarter about how you can participate in this project. In this post, he describes what really happens behind the scenes in his laboratory that helps their team discover (with your help!) new compounds from fungi that could prove to be useful in treating diseases. Find germs and microbes intriguing?Check out more microbe themed projects that we’ve picked out for you at SciStarter!

For millennia, our ancestors turned to the Earth as a source of healing agents to address all manner of illness. For example, the Ebers Papyrus (written in the vicinity of Egypt around 1500 BC) provides hundreds of examples of medicinal plants and minerals used to treat many disease conditions including pain, vomiting, and infections. Fast forward to modern times and we see that the research methods used to study diseases have changed dramatically, but the idea that the Earth is the best source of lifesaving drugs has endured. The philosophy that our planet still holds many secrets to modern ailments is substantiated by a large and growing list of drugs that come from nature. Read the rest of this entry »

Astronauts Tracking Microbe Growth on the International Space Station This Week

By December 10th, 2014 at 11:03 pm | Comment

Microbe Growth Documented for Analysis and Interpretation by UC Davis Scientists

Davis, CA. (December 10, 2014) – This week on the International Space Station, astronaut Terry Virts is measuring the growth of microbes collected by citizen scientists across the United States.

This citizen science research, known as Project MERCCURI, investigates how microbes from different places on Earth compare to each other and to those found on the International Space Station.

The microbes shot into space on a SpaceX Falcon 9 rocket in April of this year. The microbes rested in a freezer at -80°C until the testing began earlier this week. UC Davis has received confirmation that the microbes are now growing in space, and the team in the Microbiology Lab will soon analyze the data on the individual microbes to see which won the “Microbial Playoffs.” Scientists are looking for winning microbes in three different categories: Read the rest of this entry »
