Just discovered this report: BEACON eSpace at Jet Propulsion Laboratory: Genetic inventory task final report. It is a summary of genetic studies of microbes found on various spacecraft and associated facilities. Abstract: Contaminant terrestrial microbiota could profoundly impact the scientific integrity of extraterrestrial life-detection experiments. It is therefore important to know what organisms persist on spacecraft …
I haven’t posted in awhile about Project MERCCURI but we’ve been plugging along preparing all of our candidate bacteria to fly to the space station. This process turned out to be much much more work that we anticipated. In the end we grew up many hundreds of strains from events around the country in order …
Sometimes blogging on microBEnet feels a bit like a MadLib. There are certain recurring themes that fit the model well. For example: __________ (microbe) was recently found to do _______________ (cool thing)… IN SPAAAAACE! This has implications for future manned spaceflight missions. So here we go for today: The fungal pathogen Candida albicans was recently …
It’s becoming increasingly well-established that microbes behave differently in microgravity than on Earth… that’s one of the justifications for our own Project MERCCURI. Some previous work has focused on the ability of microbes to survive higher-than-normal levels of antibiotics when grown in space, though the mechanism for this is not at all understood. This article …
The study of how aerosols disperse and settle is an important part of the microbiology of the built environment and there are several groups working on the topic. However, this story was the first I’ve heard about modeling this process in zero gravity. The settling of aerosols in particular is quite different in spacecraft than …
A nice little video featuring Jenna and Jonathan talking about Project MERCCURI:
I was recently encouraged to post this video I made with a couple of classmates while I was in graduate school at the University of Texas at Austin (the other “actors” are Laura Reed, now a PhD student in water resources at Tufts University, and Sarah Taylor Lange, who just finished her PhD in concrete …
The Today Show did a follow up piece after we identified a couple of bacteria collected on their set, one of which will go up to the International Space Station in February (see the first piece here). I tried to craft the message here that microbes are everywhere and most of them are harmless or …
Abstracts are sought to address building science issues in the Alfred P. Sloan Foundation’s program, Microbiology of the Built Environment. The Sloan Foundation is sponsoring a symposium as an important part of the conference. The emphasis of the Sloan Symposium will be on the building science aspects of studies of the indoor microbiome — in …
Many indoor environmental investigators have attempted to use volatile organic compounds (VOCs) emitted by microbes as an indicator of the presence or potential health relevance of the indoor microbiome. These compounds emitted by microbes are generally referred to as MVOCs. The airborne concentrations of MVOCs is usually too low for characterization by the usual indoor …
