A question about Xylose production in E. coli B cells

... should add, the end product of anaerobic glycolysis is ethanol (from the reduction of pyruvate produced by passage through the citric acid cycle). Xylose will probably go through the pentose phosphate pathway and I'm not certain what the end product there is. One of the final products is GA3P, ...

A question about Xylose production in E. coli B cells

... Yeast and bacteria are pretty good at utilizing whatever sugars happen to be around. Glucose, if it's around, will be the preferred source, but if xylose happens to be in abundance, they will happily turn on the xylose utilization pathways and go merrily on their metabolic way.

A question about Xylose production in E. coli B cells

... you for your reply blcr, i will look this up. There is also something not clear to me about fermentation, if there's said: "fermentation of xylose" what does this mean exactly. Does it mean the anabolism of xylose from other molecules, or does it mean the catabolism of xylose like in ...

A question about Xylose production in E. coli B cells

Boy, I really don't know how to suggest anything here. Does any bacterium actually make carbohydrate? They utilize sugars (including xylose), but that's catabolism, not anabolism. There's gluconeogenesis in animal cells and there are epimerases that might interconvert an array of sugars, ...

A question about Xylose production in E. coli B cells

Hello, I am interested in the production of Xylose in E.coli B cells. I guess the gene(s) for Xylose are probably not present in the E.coli B genome, so a modification in the genome/plasmid is needed. When this is done, how can the effect of the ...
