GM Bacteria for fermentation

[Eric]

Hi,
I would like to know about the genetically modified bacteria used for the fermentation.... Are there any advantages in using these GMO s rather than traditional yeast??

[sreevatsansumukhi]

Do all these companies in the bioethanol production use genetically modified organisms for ethanol production from cellulose??

No, I doubt if they use genetically modified enzymes.. They use enzymes which are naturally produced for ethanol production.. For example,Iogen is a cellulosic ethanol company which uses naturally produced enzymes( which they produce on their own) to produce cellulosic ethanol.

Hi,

I am new to this forum. I saw an interesting article on how GMOs were used to naturally sweeten diary products.

Lactose is a disaccharide, made up of two basic sugar molecules, a galactose and a glucose molecule. In the Lactococcus lactis strain, used extensively in the dairy industry in the production of fermented milk products, certain genes in the lactose-PTS were deleted to create a bacterium (NZ9000Glc-Lac+) that selectively fermented the galactose part of the lactose, but not the glucose part. The glucose then accumulated outside of the cell, in the dairy product which gives a sweet taste naturally.
