Microbes and Toxins, Oh My.

This recent article in Science Daily tells of a bacteria that “breathes” poisons, like antimony and arsenic. It also reduces contaminants, like selenium and tellurium, often found in wastewater from mines and refineries. Isolated from Mono Lake by researchers from the University of Georgia, this bacteria enjoys hot, high salt environments. Interesting implications of this bacteria’s …

Sloan MBE grantees: Save the date, June 4-6 for the 3rd annual conference in Boulder

Just a quick “save the date” note here.  The 3rd annual Conference on the Microbiology of the Built Environment will be held at the Boulder Marriott (same as last year) on June 4-6 2014.  This conference is typically limited to Sloan grantees, their labs, and various folks from the field invited by the Sloan Foundation. …

The Astronaut Microbiome

The human microbiome and microbes in space are two of the sexiest topics in microbiology today. Together they have attracted the attention of the J. Craig Venter Institute. Hernan Lorenzi is leading a team to study how the composition of the human microbiome changes during long term space exploration. They will be analyzing the microbiome of …

Dusty Houses and Type 1 Diabetes

Among the cleanest and wealthiest countries in the world, Finland has the highest rate of Type 1 diabetes, while other messier and poorer countries have much lower rates. A recent article in the Washington Post discusses ongoing research to explore how exposure to dust and bacteria in houses might contribute to the onset of Type …

Salmonella Biofilm 1, Disinfectants 0

US news just published an article, Disinfectants Can’t Defeat Salmonella in Food-Processing Plants: Study, discussing the inability of currently used disinfectants to eradicate or even reduce viable counts of Salmonella. The full article, Commonly used disinfectants fail to eradicate Salmonella enterica biofilm from food contact surface materials, is located behind a paywall in the Journal of Applied and Environmental Microbiology …

NASA report of interest (from 2012): Genetic inventory (of spacecraft) task final report

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 …

Careful Consideration of Bioinformatic Pipeline Choices Based on Study Goals

Sequencing of PCR-amplified marker regions (e.g. 16S, ITS) for characterization of sample microbial ecology is a widely-used tool in Microbiology of the Built Environmenta (MoBE) investigations. Due to the large amount of data produced by these methods, sequences are typically clustered into operational taxonomic units (OTUs) based on sequence similarity to simplify downstream processing. However, …

Long read on “bioMASON” company

There is an interesting article in the News Observer of relevance to microBEnet: NC startup develops a way to turn sand into bricks with bacteria instead of heat | Science/Technology | NewsObserver.com. There are parts I am a bit skeptical of but the article tells the story of Ginger Kreig Dosier and her company “bioMASON” …

Cell phone sterilizer? Really?

So earlier this week I wrote an article at Slate called “I would rather lick a toilet seat than cell phone”.  Which was a really unfortunate title since I was trying to emphasize that toilet seats are surprisingly clean and the general point of the article was about microbial scare stories.  I did not mean …
