Etanol versus bioeletricidade: aplicação dos conceitos de fronteira eficiente de Markowitz para o aproveitamento do bagaço residual do setor sucroenergético
… work analyzes the competition for bagasse in the lignocellulosic ethanol and electricity productions using the modern portfolio theory developed by Markowitz, as the sector can further diversify its production, reducing risks and increasing returns. After literature review, about sugar-energy …

Reducing cell wall recalcitrance in poplar through overexpression of cell wall degrading enzymes
… cellulose in the secondary cell walls of lignocellulosic biomass provides an alternative source of carbohydrates for ethanol production. However, low efficiency and high cost of conversion of cellulose to glucose prevents the large-scale production of economically viable cellulosic …

Discovery and characterization of pentose-specific transporters in Saccharomyces cerevisiae
… one of the most promising organisms for ethanol production from lignocellulosic feedstock. Unfortunately, pentose sugars, which make up to 30% of lignocellulose, cannot be utilized by S. cerevisiae. Pentoses can only enter yeast cells through hexose transporters, which have two orders of …

The genetic control of stem mechanical properties in Brassica Napus and Wheat
… exploitation of crop residues as feedstock for lignocellulosic ethanol production, where the manipulation of cell wall chemical composition to improve feedstock processibility may lead to reduced stem strength. Lodging is a widespread problem in both Brassica napus (B. napus) and wheat, and is a …

Preliminary quantitative trait loci analysis for biomass traits in Miscanthus sinensis
In light of rising energy costs, lignocellulosic ethanol has been identified as a renewable alternative to the petroleum based transportation fuels. In an attempt to reach government mandated ethanol production levels, potential biofeedstock candidates have been investigated and accessions within …

Biomass to ethanol : potential production and environmental impacts
… fuel consumption and greenhouse gas impacts of ethanol produced from three feedstocks; corn grain, corn stover, and switchgrass. A life-cycle assessment approach with an integrated Monte Carlo uncertainty analysis is applied to each of these three bioethanol pathways. Incorporating a Monte Carlo …

Life Cycle Environmental and Cost Evaluation of Bioenergy Systems
… examines implications of replacing gasoline with ethanol for use in California’s light-duty vehicle fleet to meet the State’s Low Carbon Fuel Standard (LCFS). The Ontario studies show that, relative to coal-based electricity generation, electricity generated from co-firing 10% (energy input) …

Metabolic engineering of Saccharomyces cerevisiae for efficient ethanol production from pentose sugars
… that of converting plant-derived lignocellulosic material into biofuels. Saccharomyces cerevisiae, also known as baker’s yeast, is considered one of the most promising organisms for ethanol production from lignocellulosic feedstock. Unfortunately, pentose sugars, which constitute …

Hydrothermal liquefaction of low-lipid microalgae to produce bio-crude oil
… food production compared with grain and other lignocellulosic biomass. However, current lipid-to-biodiesel technology primarily focuses on utilizing high-lipid algae, which usually has lower biomass productivities than low-lipid algal strains. In addition, biodiesel production from algae often …
