Enhanced Ethanol Fermentation
Using bioDigestate ("EIEP")
The automaker said, 'As a result, the yeast has achieved one of the highest ethanol fermentation
density levels in the world (approximately 47 grams per litre), and is expected to improve biofuel yield and significantly reduce production costs.
As a result, the yeast has achieved one of the highest ethanol fermentation
density levels in the world* (approximately 47 g/liter), and is expected to improve bio-fuel yield and significantly reduce production costs.
The transgenic lines require lower temperature preprocessing and only one-quarter to one-third the level of enzymes for equivalent ethanol fermentation
compared to the unmodified switch-grass.
Large scale ethanol fermentation
through pipeline delivery of biomass.
The time course of the ethanol fermentation
and the final ethanol concentration achieved were very similar to those obtained by fermentation which followed twostep enzymatic actions.
The estimated operating cost assumes that whey permeate used in ethanol fermentation
is a free (no cost) feedstock.
The purpose of this research was to study the effect of selected by-products in an acid hydrolysate on cell growth and ethanol fermentation
of Saccharomyces cerevisiae.
DuPont and BP are working with British Sugar to convert the country's first ethanol fermentation
facility to produce biobutanol.
This method potentially reduces the amount of labor involved in isolating and screening yeast strains as effective ethanol fermentation
agents," said inventor Dr.
