Fuel ethanol after 25 years.
TLDR
After 25 years, Brazil and North America are still the only two regions that produce large quantities of fuel ethanol, from sugar cane and maize, respectively, but only tax credits make fuel ethanol commercially viable because oil prices are at an all-time low.About:

Journal ArticleDOI
Hydrolysis of lignocellulosic materials for ethanol production: a review.
Ye Sun,Jiayang Cheng +1 more
TL;DR: Simultaneous saccharification and fermentation effectively removes glucose, which is an inhibitor to cellulase activity, thus increasing the yield and rate of cellulose hydrolysis, thereby increasing the cost of ethanol production from lignocellulosic materials.
Journal ArticleDOI
Technology development for the production of biobased products from biorefinery carbohydrates—the US Department of Energy’s “Top 10” revisited
TL;DR: An updated evaluation of potential target structures using similar selection methodology, and an overview of the technology developments that led to the inclusion of a given compound are presented.
Journal ArticleDOI
Ethanol fermentation from biomass resources: current state and prospects.
Yan Lin,Shuzo Tanaka +1 more
TL;DR: The prospects included are fermentation technology converting xylose to ethanol, cellulase enzyme utilized in the hydrolysis of lignocellulosic materials, immobilization of the microorganism in large systems, simultaneous saccharification and fermentation, and sugar conversion into ethanol.
Journal ArticleDOI
Hydrothermal liquefaction of biomass: A review of subcritical water technologies
TL;DR: In this paper, the authors present a review of the current status of the hydrothermal liquefaction of biomass with the aim of describing the current state of the technology, which is a medium-temperature, high-pressure thermochemical process which produces a liquid product, often called bio-oil or bi-crude.
Journal ArticleDOI
Industrial enzyme applications.
TL;DR: The development of enzymes with improved properties for established technical applications and in the production of new enzymes tailor-made for entirely new areas of application where enzymes have not previously been used are studied.

David Pimentel,Celia A. Harvey,P. Resosudarmo,K. Sinclair,D. Kurz,M. McNair,S. Crist,L. Shpritz,L. Fitton,R. Saffouri,R. Blair +10 more
TL;DR: With the addition of a quarter of a million people each day, the world population's food demand is increasing at a time when per capita food productivity is beginning to decline.
Journal ArticleDOI
Fuel ethanol from cellulosic biomass.
TL;DR: Ethanol produced from cellulosic biomass is examined as a large-scale transportation fuel and a cost-competitive process appears possible in a decade, with conversion economics the key obstacle to be overcome.

Handbook on bioethanol : production and utilization
TL;DR: A review of pilot plant programs for bio-ethanol conversion from lignocellulosic biomass can be found in this article, where the authors discuss the economic, economic, and environmental issues for transportation fuels.
Journal ArticleDOI
OVERVIEW AND EVALUATION OF FUEL ETHANOL FROM CELLULOSIC BIOMASS: Technology, Economics, the Environment, and Policy
TL;DR: In this article, it is shown that ethanol may be more compatible with fuel cell-powered vehicles than has generally been assumed, and it is likely that vehicles can be configured so that exhaust emissions of priority pollutants are very low for ethanol-burning engines, although the same can probably be said for most other fuels under consideration.
Journal ArticleDOI
Effects of lignocellulose degradation products on ethanol fermentations of glucose and xylose by Saccharomyces cerevisiae, Zymomonas mobilis, Pichia stipitis, and Candida shehatae
TL;DR: Analysis of culture media extracts showed that some of the inhibitors, particularly vanillin and furaldehyde, could be assimilated by the tested microbial strains which resulted in the partial recovery in both growth and ethanol production processes on prolonged incubation.
