Enzymatic hydrolusis of cellulose

[Eric]

Hi,
can any one tell me........What are the enzymes used for hydrolysis of cellulose?
What are the available sources for these enzymes?

An example of an enzymatic hydrolysis-based process is under development by the National Renewable
Energy Laboratory (NREL). After a dilute acid pretreatment, the slurry is detoxified to remove materials that
would be poisonous to the microorganisms used in the process. A small part of this slurry is sent to a separate
vessel that is used to grow microorganisms that produce the cellulase enzyme for the process. Another part of
the slurry is sent to another vessel to maintain and grow a yeast culture for fermentation. In the NREL process,
both enzymes and the fermentation microorganisms are added at the same time to the slurry, and sugar
conversion and fermentation occur simultaneously in a process called simultaneous saccharification and cofermentation
(SSCF).

Can someone gimme details about the top companies and research centres or associations working on the enzymatic hydrolysis of cellulosic biomass .I am interested in doing a summer internship in this field.

Thanks in advance!!

There are many companies doing research on cellulosic ethanol and it is believed to have great prospects in the near future.

Follow the link and you should be able to get required details on the comapanies working in this exciting field.

Do these companies produce the enzyme on their own ??

Hi..

Yes, the companies produce their own enzymes for using them duirng the cellulosic ethanol production..

For example, Iogen is a world leader in cellulosic ethanol production and is known to produce its own enzymes and has its own methods to produce cellulosic ethanol..
