Recent advances in molecular biology have extended our understanding of the metabolic
processes related to microbial transformation of petroleum hydrocarbons. The physiological …

Our environment is essential for not only the quality, but also the persistence of life on Earth.
Three of the most pressing environmental issues facing modern society are climate change …

Cylindrical colloidal-silver-impregnated ceramic filters for household (point-of-use) water
treatment were manufactured and tested for performance in the laboratory with respect to …

Many motile microorganisms swim and navigate in chemically and mechanically complex
environments. These organisms can be functionalized and directly used for applications …

Background Roots growing in soil encounter physical, chemical and biological
environments that influence their rhizospheres and affect plant growth. Exudates from roots …

Contaminant hydrogeological processes occurring in porous media are typically not
amenable to direct observation. As a result, indirect measurements (eg, contaminant …

The technological performance and social acceptance of ceramic water filters impregnated
with silver nanoparticles for point-of-use water treatment were investigated in the laboratory …

In a handful of fertile soil there are billions of microorganisms and yet, even with a
conservative estimate, the surface area covered by these organisms is considerably less …

Microorganisms have played a critical role in geological processes and in the formation of
soils throughout the geological times. It is hypothesized that biological activity can also affect …

We describe a boundary-element method used to model the hydrodynamics of a bacterium
propelled by a single helical flagellum. Using this model, we optimize the power efficiency of …
