  • New techniques create butanol, a superior biofuel

    The fuel is butanol; it can be derived from lignocellulosic materials, which are plant biomass parts that range from woody stems and straw to agricultural residues, corn fiber and husks, all containing in large part cellulose and some lignin. Butanol is considered to be a better biofuel than ethanol because it's less corrosive and has a higher caloric value, giving it a higher energy value. Like ...

  • Through microbes, nitrogen alters soil carbon cycle

    Soil scientists studying bacterial communities in hardwood forests have found evidence that extra human-derived nitrogen deposited from the atmosphere can change the composition of the soil microbial community, with implications for carbon cycling and sequestration. Don Zak and Sarah Eisenlord from the University of Michigan conducted a study on the response the soil bacterial community to levels ...

  • ASTM E1366 - 11 standard practice for standardized aquatic microcosms: fresh water

    A microcosm test is conducted to obtain information concerning toxicity or other effects of a test material on the interactions among three trophic levels (primary, secondary, and detrital) and the competitive interactions within each trophic level. As with ...
