MC ALOON, ANDREW /et al/ | Colorado [ESTADOS UNIDOS] : National Renewable Energy Laboratory | Technical Report | 2000The mature corn-to-ethanol industry has many similarities to the emerging lignocelluloseto-ethanol industry. It is certainly possible that some of the early practitioners of this new technology will be the current corn ethanol producers. In orde[...]texto impreso

The ethanol yield and productivity obtained during fermentation of lignocellulosic hydrolysates is decreased due to the presence of inhibiting compounds, such as weak acids, furans and phenolic compounds formed or released during hydrolysis. Thi[...]texto impreso
During hydrolysis of lignocellulosic materials a wide range of compounds which are inhibitory to microorganisms are formed or released. Based on their origin the inhibitors are usually divided in three major groups: weak acids, furan derivatives[...]texto impreso
Lignocellulosic biomass can be utilized to produce ethanol, a promising alternative energy source for the limited crude oil. There are mainly two processes involved in the conversion: hydrolysis of cellulose in the lignocellulosic biomass to pro[...]texto impreso
The presumed high cost of cellulase enzymes is seen as a major economic hurdle in ethanol fuel production from lignocellulosic biomass. One way to reduce enzyme cost is to use much less enzyme per unit of biomass hydrolysed. The ammonia fiber ex[...]texto impreso
ADEN, A. /et al/ | Colorado [ESTADOS UNIDOS] : National Renewable Energy Laboratory | Technical Report | 2002The U.S. Department of Energy (DOE) is promoting the development of ethanol from lignocellulosic feedstocks as an alternative to conventional petroleum-based transportation fuels. DOE funds both fundamental and applied research in this area and [...]texto impreso
Lignocellulosic biomass may be used as a potential renewable feedstock for biochemical production of ethanol as an alternative transportation fuel. However, cellulose, which is the major source of fermentable sugars in these materials, is protec[...]texto impreso
