Study identifies functional roles of individuals within microbial consortium for breaking down switchgrass for biofuel production

Green Car Congress

By comparison, the more numerous Rhodothermus strain contributed fewer enzymes to biomass deconstruction. However, based on the assigned fractions of the switchgrass deconstruction proteome, the strains showing the most active role in switchgrass deconstruction were Gemmatimonadetes and Paenibacillus.

California ARB mods to ZEV regulations for IVMs would result in ~1.9% drop in total ZEV/TZEV units 2018-2025; no impact on air quality requirements

Green Car Congress

In comparison, the IVMs face the comparatively difficult technological challenge of transitioning from compliance solely with PZEVs to compliance with TZEVs. LVMs also received extended service credit for allowing consumers to either extend a lease or exercise a purchase option at the end of a lease.
