The Energy Independence and Security Act spurred cellulosic ethanol biorefineries, driving interest in dedicated energy crops for biofuel production. Improving biomass productivity offers new opportunities for expanding biofuel potential beyond traditional crop research.
Area of Science:
- Biomass energy
- Biofuel production
- Agricultural science
Background:
- The Energy Independence and Security Act (EISA) of 2007 and Renewable Fuel Standard (RFS2) have driven the development of commercial cellulosic ethanol biorefineries.
- This has renewed focus on dedicated energy crops optimized for biomass yield and conversion efficiency.
Purpose of the Study:
- To explore the development of dedicated energy crops for cellulosic ethanol production.
- To investigate opportunities for expanding biofuel potential through enhanced biomass productivity.
Main Methods:
- Review of policy drivers (EISA, RFS2) and their impact on biorefinery development.
- Analysis of agricultural strategies for dedicated energy crop cultivation.
- Assessment of biomass properties relevant to liquid fuel conversion.
Main Results:
- Commercial-scale cellulosic ethanol biorefineries are emerging due to policy incentives.
- Dedicated energy crops are being developed for improved biomass productivity and conversion efficiency.
- Biomass productivity improvements offer avenues to expand biofuel production capacity.
Conclusions:
- Policy frameworks are successfully stimulating the cellulosic ethanol industry.
- Development of specialized energy crops is crucial for advancing biofuel production.
- Enhancing biomass productivity in energy crops presents significant potential for increasing biofuel output.

Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
