Hi,
I found this interesting research by Ming-De Deng and John R. Coleman Department of Botany, University of Toronto similar to Fu's....

The coding sequences of pyruvate decarboxylase (pdc) and alcohol dehydrogenase II (adh) from the bacterium Zymomonas mobilis were cloned into the shuttle vector pCB4 and then used to transform the cyanobacterium Synechococcus sp. strain PCC 7942. Under control of the promoter from the rbcLS operon encoding the cyanobacterial ribulose-1,5-bisphosphate carboxylase/oxygenase, the pdc and adh genes were expressed at high levels, as demonstrated by Western blotting and enzyme activity analyses. The transformed cyanobacterium synthesized ethanol, which diffused from the cells into the culture medium.

Hey guys,
forgive me if i'm wrong but does cellulosic ethanol from Algae not have the same limitation as cellulosic ethanol from land biomass eg wood chips?

why is making cellulosic ethanol from algae any easier?

Thanks,
Mubs

The growth of algal blooms in the ocean sounds like a great idea, but some have claimed that the party's stopper, who tried to manipulate the marine environment may result in unforeseen disaster.
