U.S. uses genetically modified bacteria to directly convert biomass energy into ethanol

Science and Technology Daily News from a study by the University of Georgia found that after they genetically modified the bacterial thermophilic xylanase that can degrade lignocellulose, it directly converts biomass using switchgrass as a raw material into ethanol fuel.

In the process of using switchgrass and parmesan roots and other non-food crops to produce cost-effective biofuels, one of the main “blockers” faced is the pretreatment of plants before the use of microbial fermentation to produce ethanol—the cell walls of plants must be pretreated.

Now, Janet Westfiling, a professor in the Department of Genetics at the Franklin School of Arts and Sciences at the University of Georgia, and researchers from the University’s Bioenergy Science Center (funded by the U.

Westfiling and colleagues deleted a lactate dehydrogenase gene from thermophilic xylanase and introduced an acetaldehyde/alcohol dehydrogenase gene from Clostridium thermocellum, which produces ethanol.

Westfiling said: “Now, there is no need for any pretreatment process.

Westfiling said that many microorganisms in nature have proved to have very powerful chemical and biological capabilities, but the biggest challenge is to develop a good genetic system to use these microorganisms.

In addition to ethanol, butanol and isobutanol (traffic fuels comparable to ethanol) and other fuels and chemicals are obtained
