Soils contain the largest pool of terrestrial organic carbon (C) and are a major source of atmospheric carbon dioxide (CO2). Thus, they may play a key role in modulating climate change. Rising atmospheric CO2 is expected to stimulate plant growth...

Electricity can be an energy source for microbially catalyzed production of fuels and other organic commodities from carbon dioxide. These electrobiocommodities (E-BCs) can be produced directly via electrode-to-microbe electron transfer or indirectly with electrochemically generated electron donors such as H2...

The latest advances in biocatalysis using supercritical carbon dioxide (scCO(2)) are reviewed. Stability and stabilization methodologies of enzymes in scCO(2) as well as reactions for organic synthesis are described. Especially, varieties of examples for lipase-catalyzed synthesis of chiral compounds using...
