Conversion of cropland from corn to perennial biofuel grasses for ethanol production could transition the central US from a net source to a net sink for GHGs

Green Car Congress

Conversion from a high-input annual crop to a low-input perennial crop for biofuel production can thus transition the central US from a net source to a net sink for GHGs. —Davis et al. The GHG reduction was large even after accounting for emissions associated with indirect land-use change. —William Parton.

New family of enzymes to degrade biomass into constituent sugars

Green Car Congress

Lytic polysaccharide monooxygenases (LPMOs) constitute a recently discovered class of enzymes that have attracted attention owing to their potential use in biomass conversion, notably in the production of biofuels. They report on the new family of lytic polysaccharide monooxygenases in a paper in the journal Nature Chemical Biology.
