cellulosic ethanol

[wojwrobel]

hello
i have been researching the way to make cheep ethanol and found few easy ways to make ethanol the key is to not use a expensive sugar !!!

so first method is one used by Coskata found here

so the method use a woodgas or syngas and then is introduced to microorganism that consumes gas and makes ethanol but the problem is i cant find what organizm they use ?? cant find their patent!!! so if we can just find the mane of the organizm that consumes carbon monoxide and hydrogen and produces ethanol we are set !!!!

the other way is to use cellulose and use enzymes to breake the polymers to sugars just like it happens in a cow stomake !!!!

watch this http://www.youtube.com/watch?v=dF3PS1v8nKY

very intresting , because according to this we can make ethanol from sawdust woodchips leaves grass almost any organic WITHOUT use of sugar !!! thats saves alot of money !!! 

what do you guys think

cheers from poland

ok made some more research and foud this
http://www.rpi.edu/dept/chem-eng/Biotech-Environ/FUEL/hydro.html

and according to this we can make whole process with one bacteria that will extract sugars from celluloses and ferrment it to ethanol its called
Clostridium Thermocellum

now we have to find out how efficient is this process?

cheers for now wojsciech
