End-Product Tolerance and Ethanol
1981Fossil fuels, and in particular oil and its derivatives, are the source of the vast proportion of fuels and chemicals used today in developed countries of the World. However, fossil fuels have two insurmountable drawbacks which restrict their production and utilization.

Ethanol production and the environment
Energy, 1989Abstract Ten proposed fuel-ethanol production facilities that were candidates for federal loan guarantees were evaluated under the terms of the National Environmental Policy Act to determine if they would result in significant impacts on the human environment. The plants ranged in production capacity from 58 million liters (ML) per year (15.4 million

Postmortem Ethanol Concentrations and Postmortem Ethanol Production
Academic Forensic Pathology, 2014A review of the literature was conducted in reference to postmortem blood ethanol concentrations and the issue of postmortem production of ethanol. Ethanol in postmortem specimens may occur as a result of antemortem consumption (most common), postmortem production in the body or in vitro by microorganisms (less common), and endogenous production by ...

Ethanol Production and Employment
1993Increased U.S, production of ethanol could create 28,000-108,000 new jobs by the year 2000. Ethanol distilled chiefly from corn, can be mixed with gasoline to reduce the level of hydrocarbon pollutants created by fuel combustion in gasoline engines. Job gains will be concentrated in the rural Midwest, where most of the Nation’s corn is grown.

Biotechnology Letters, 1982
The kinetic behaviour of Zymomonas mobilis is studied at temperatures from 27 °C to 34.5 °C. Increases of temperature (above a critical value) have a negative effect on the yield of ethanol, mainly by raising the maintenance coefficient. Cell growth is less inhibited by the ethanol accumulation inside the cell than is the fermentative pathway.

ETHANOL PRODUCTION BY BIOENGINEERING
Environmental Engineering and Management Journal, 2004In this paper, the biological and engineering aspects of a bioproject related to the development of a process for production of bioethanol from biomass are presented. The particular process developed was that using potatoes as the raw material.

Utilization of by-products from ethanol production as substrate for biogas production
Bioresource Technology, 2011The aims of this work were to determine the specific biogas yields of steam-exploded sugarcane straw and bagasse as well as to estimate their energy potential under Brazilian conditions. Steam-explosion was carried out under different time and temperature conditions. The specific biogas yields were analyzed in batch-tests according to VDI 4630. Results

Production of ethanol and xylitol by Trametes membranacea
Bioprocess and Biosystems Engineering, 2018The potential to produce ethanol and xylitol from xylose by the macro basidiomycete Trametes membranacea was evaluated. All strains studied showed ethanol and xylitol production. The highest ethanol production of xylose was obtained by T. membranacea strain TM158/10 with 5.65 ± 0.21 g/L at pH 4 and 28 °C with 288 h of fermentation and 5.59 ± 0.05 g/L ...

Starch Characterization and Ethanol Production of Sorghum
Journal of Agricultural and Food Chemistry, 2011This study aimed to characterize and compare the chemical structures, physical properties, and enzymatic hydrolysis rates of five sorghum starches (6B73, 6C21, 6C69, 7R34, and X789) with that of corn starch (B73). Sorghum kernels consisted of 68.7-70.6% starch, more than the B73 corn (67.4%).

Metabolic engineering of bacteria for ethanol production
Biotechnology and Bioengineering, 1998Technologies are available which will allow the conversion of lignocellulose into fuel ethanol using genetically engineered bacteria. Assembling these into a cost-effective process remains a challenge. Our work has focused primarily on the genetic engineering of enteric bacteria using a portable ethanol production pathway.
