Sentences with phrase «isobutanol production»

In the present study, we used protein engineering of Kivd to improve isobutanol production in Synechocystis PCC 6803.

Single replacement, either Val461 to isoleucine or Ser286 to threonine, increased the Kivd activity significantly, both in vivo and in vitro resulting in increased overall production while isobutanol production was increased more than 3 - methyl -1-butanol production.

Using their light - switch technique, the researchers set out to keep the yeast alive while maximizing isobutanol production.

The researchers predicted they could use a combination of genetic engineering and light to fine tune isobutanol production.

Not exact matches

Efforts to make isobutanol from bacteria alone have been underway since 2000 when the U.S. Department of Agriculture and the U.S. Department of Energy (DOE) began distributing grants to universities that could demonstrate successful production of liquid biofuels.

However, most attempts to create isobutanol biofuel have run into difficulties involving cost or scaling production to an industrial level.

Using their new technique, the Princeton researchers have now used fermentation and genetically - engineered yeast to produce other chemicals including lactic acid, used in food production and bioplastics, and isobutanol, a commodity chemical and an advanced biofuel.

But while those enzymes are active, ones that influence the production of isobutanol can't work.

Moreover, among all the engineered strains examined, the strain with the combined modification V461I / S286T showed the highest (2.4 times) improvement of isobutanol - to - 3M1B molar ratio, which was due to a decrease of the activity towards 3M1B production.
