Now, a team of researchers from the University of Illinois at Urbana-Champaign and the Universite Paul Sabatier in Toulouse, France, has developed a microreactor that efficiently regenerates cofactors through enzyme-...

Device traps, disables harmful bacteria

...e researchers also tested the hybrid filters in an environmentally controlled laboratory chamber to come up with the air-exchange rate for the therapy pool assays, among other parameters. The researchers published their results in the Feb. 2005 issue of the Journal of Air & Waste Management Association. The stu...

Aquatic plants may hold key to advancing plant disease management

...management of freshwater plant disease has created environmentally sound methods of plant disease control. While plant pathologists typically try to save plants from plant disease, plant pathologists can use plant pathogens as a means to control highly invasive freshwater plants that harm native aquatic plants. Stud...

Techniques available to detect soil that inhibits destructive soybean pest

...matode-suppressive soils is an easily implemented, environmentally friendly weapon in fighting the parasites, which are found worldwide in soybean-producing areas. "Using plants bred to resist pests is not the complete answer, so it's important to find suppressive mechanisms," Westphal said. "Bio-control is much mo...
