Researchers demonstrate way to control tree height

...e extensive root development is needed, such as in bioremediation of polluted soils or in very windy, limited soil moisture situations. From an environmental viewpoint, the researchers said, dwarfed trees such as this are unlikely to be any kind of threat to spread, because they would compete very poorly with no...

Researchers develop way to calculate speed of bacterial sex

... positive environmental outcomes, such as improved bioremediation qualities, bacterial adaptation can also create potentially harmful bacteria that are resistant to antibiotics and increase gene flow from genetically modified organisms to native soils. By developing a real-life model of bacterial gene transfer, UC-...

Particle size matters to bacteria ability to immobilize heavy metals

...by Shewanella and its application in environmental bioremediation of contaminated DOE sites. "It will help build a whole picture of Shewanella ?how it reacts with metal oxides and how the rate of this interaction is influenced by size" Bose said. So far, the research shows that particles of similar shape but diff...

Tiny particles could solve billion-dollar problem

...mical catalysis offers faster reactions times than bioremediation schemes but also tends to be more expensive. One of the major advantages of using palladium catalysts to break down TCE is that palladium converts TCE directly into non-toxic ethane. By contrast, breaking down TCE with more common catalysts, like ir...
