Feedstocks for Lignocellulosic Biofuels

Science, 2010
In 2008, the world produced approximately 87 gigaliters of liquid biofuels, which is roughly equal to the volume of liquid fuel consumed by Germany that year. Essentially, all of this biofuel was produced from crops developed for food production, raising concerns about the net energy and greenhouse gas effects and potential competition between use of ...

Butanol production from lignocellulosics

Biotechnology Letters, 2012
Clostridium spp. produce n-butanol in the acetone/butanol/ethanol process. For sustainable industrial scale butanol production, a number of obstacles need to be addressed including choice of feedstock, the low product yield, toxicity to production strain, multiple-end products and downstream processing of alcohol mixtures. This review describes the use

Various pretreatments of lignocellulosics

Bioresource Technology, 2016
Biomass pretreatment for depolymerizing lignocellulosics to fermentable sugars has been studied for nearly 200 years. Researches have aimed at high sugar production with minimal degradation to inhibitory compounds. Chemical, physico-chemical and biochemical conversions are the most promising technologies.

Bioethanol from Lignocellulosic Biomass

2011
China is suffering from a sustained shortage of crude oil supply, making fuel ethanol and other biofuels alternative solutions for this issue. However, taking into account the country's large population and dwindling arable land due to rapid urbanization, it is apparent that current fuel ethanol production from grain-based feedstocks is not sustainable,

Pretreatment of Lignocellulosic Feedstocks

2017
With the aim of reducing greenhouse gas (GHG) emissions and with our dependence on non-renewable fossil fuels, lignocellulose has been proposed to be an alternative sugar-rich raw material for renewable biofuel production, especially for the transportation sector.

Cellulose from Lignocellulosic Waste

2014
Bioconversion of renewable lignocellulosic biomass to biofuel and value-added products is globally gaining significant importance. Lignocellulosic wastes are the most promising feedstock considering its great availability and low cost. Biomass conversion process involves mainly two steps: hydrolysis of cellulose in the lignocellulosic biomass to ...

Lignocellulose-Biorefinery: Ethanol-Focused

2017
The development prospects of the world markets for petroleum and other liquid fuels are diverse and partly contradictory. However, comprehensive changes for the energy supply of the future are essential. Notwithstanding the fact that there are still very large deposits of energy resources from a geological point of view, the finite nature of ...

Thermostable Enzymes in Lignocellulose Hydrolysis

2007
Thermostable enzymes offer potential benefits in the hydrolysis of lignocellulosic substrates; higher specific activity decreasing the amount of enzymes, enhanced stability allowing improved hydrolysis performance and increased flexibility with respect to process configurations, all leading to improvement of the overall economy of the process.

Bioprocessing of lignocelluloses

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1987
Lignocelluloses represent a major source of renewable organic matter. Development of biological processing strategies normally must consider some form of pretreatment, hydrolysis of the polymers and bioutilization or bioconversion of these molecules to useful products.
