Phil Stewart, Principal Investigator and CBE Director, received funding from the NSF-MRI Program and the M.J. Murdock Charitable Trust for the purchase of new confocal microscope equipment in the fall of 2010. The National Science Foundation awarded $498,433 for the project: "MRI: Acquisition of a State of the Art Confocal Microscope at the Center for Biofilm Engineering." The NSF grant was awarded in conjunction with a complementary cost-sharing grant of $406,500 from the M.J. Murdock Charitable Trust.

Varied physiological responses of the facultative γ-proteobacterium, Shewanella oneidensis MR-1, and the δ-proteobacterium Desulfovibrio vulgaris hildenborough to oxygen
Evolution of molecular oxygen and accumulation in Earth’s atmosphere is considered to be the one of the most significant changes on Earth that impacted the evolution of life. Over the past 600 million years, there have been fluctuations in atmospheric oxygen concentrations that have driven the evolution of species in all three domains of life. Anaerobic microorganisms, some of the earliest life forms originated approximately 3.5- to 4 billion years ago when Earth’s atmosphere was strictly anaerobic.

Factors influencing the fate of chromium in soils: Microbial ecology, physiology and metal transformation studies
Chromium is a common contaminant in soil environments, especially at Department of Energy sites. The fate of chromium in the environment is influenced by a number of factors including the microbial processes and the interactions with soil constituents such as carbon sources, iron minerals and electron shuttling compounds.

The Powder River Basin in southeastern Montana and northeast Wyoming is the largest source of coal mined in the United States, but most of the coal contained in the basin is buried too deeply to be economically accessible. These remote coal beds are dynamic zones where biogeochemical processes work to sustain life. Previous work has shown that a direct byproduct of these life processes is biogenic methane, the principle component of natural gas that can be used as an energy source for electricity generation, heat and transportation fuel.

The CBE garnered the cover image and feature article in the September 2011 issue of Microscopy Today. The cover image, obtained with a confocal scanning laser microscope (CSLM) by Logan Schultz and Betsey Pitts of the CBE, shows four reconstructed digital image slices through clusters of Sporosarcina pasteurii bacteria growing around calcium carbonate precipitates inside a glass capillary.
