104 g/g of fermentable
sugar yield which corresponds to 20.
The negative effect of supplementing large amounts of readily fermentable
carbohydrate on fiber digestibility has been previously reported (Kosloski et al.
These toxic materials hinder the bioconversion of fermentable
sugar which is produced in hydrolysis processes .
This could be very beneficial for the production of bioenergy crops where higher proportions of enzyme-accessible fermentable
sugars, such as those in glucomannan, could lead to higher yields of fuel.
HCL's technology uses an old, industrially proven German process to create the fermentable
sugars that are seen as the gateway to advanced biofuels (biobutanols, biodiesel, jet fuel, etc.
Their ammonia fiber expansion (AFEX) solution extracts the fermentable
sugars for ethanol in a single step rather than the three steps ordinarily used.
Palo Alto, CA) has patented methods to enhance the production of more highly fermentable
carbohydrates in plants, especially forage grasses.
Termites can efficiently convert milligrams of lignocellulose into fermentable
sugars in their tiny bioreactor hindguts.
With roots in the renewable based plastics business, ZeaChem CEO and co- founder Dan Verser joined with CTO and co-founder Tim Eggeman, to invent a new process that allows both fermentable
portions of a variety of cellulosic feedstocks to contribute chemical energy to ethanol while consuming all of the carbon in the process.
The companies said that converting biomass to biofuels requires breakthrough developments in three areas: chemical preparation of the cellulosic biomass, conversion of pretreated cellulosic biomass to fermentable
sugars by combinations of enzymes, and the development of novel micro-organisms to ferment the sugars to ethanol or other fuels.
He explains there is a need to increase sorghum's fermentable
, extractable sugars to compete with other feedstocks utilized in ethanol production.
It's this grain's abundant and complex starches that are broken down into fermentable
sugars during the beer-making process.
