Comparing Life-Cycle Carbon and energy Impacts for biofuel, Wood Product, and Forest Management Alternatives

The use of wood products and biofuels to substitute for fossil fuel–intensive nonwood products or fossil fuels directly reduces the oneway flow of fossil fuel carbon emissions to the atmosphere. The focus of this article is on characterizing the hierarchy of alternative uses of biomass that reduce global warming potential measured by greenhouse gas emissions and on characterizing the impact of liquid biomass fuels that can also directly reduce energy dependence.

Performance and Emission Characteristics of a Diesel Engine Using Isobutanol–diesel Fuel Blends

The aim of this study is to investigate the suitability of isobutanol–diesel fuel blends as an alternative fuel for the diesel engine, and experimentally determine their effects on the engine performance and exhaust emissions, namely break power, break specific fuel consumption (BSFC), break thermal efficiency (BTE) and emissions of CO, HC and NOx.

High-flux Isobutanol Production using Engineered Escherichia coli: A Bioreactor Study with in situ Product Removal

Promising approaches to produce higher alcohols, e.g., isobutanol, using Escherichia coli have been developed with successful results. This research translates the isobutanol process from shake flasks to a 1-L bioreactor in order to characterize three E. coli strains.

Metabolic Engineering of Clostridium cellulolyticum for Production of Isobutanol from Cellulose

Producing biofuels directly from cellulose, known as consolidated bioprocessing, is believed to reduce costs substantially compared to a process in which cellulose degradation and fermentation to fuel are accomplished in separate steps. This research presents a metabolic engineering example for the development of a Clostridium cellulolyticum strain for isobutanol synthesis directly from cellulose.
