Recently, a research result published by researchers from the Korea Academy of Science and Technology (KAIST) in the international academic journal "Nature Chemical Biology" has attracted much attention. Using genetically modified bacteria to convert glucose, which is widespread in nature, to biodiesel for vehicles, and breaking the current bioconversion efficiency, it provides new ideas for the efficient and sustainable production of biofuels in the future.
All along, standard biodiesel comes from vegetable oils or animal fats. Fatty acids and corresponding esters are produced through organic chemical reactions. The raw materials include rapeseed oil, soybean oil, corn oil, lard, fish oil and other common substances. . However, both vegetable oil and animal fat need to occupy a large amount of land resources. If large-scale production of biofuels and the realization of fossil energy replacement are required, a large amount of land needs to be used. Not only is the cost relatively high, but it may also cause corresponding ecological problems. The proposed research results have solved this problem.
The paper is titled "Oil-producing Bacteria Engineering for Fatty Acids and Fuels." The paper points out that instead of occupying a large amount of land, instead of using glucose that is widespread in nature, and using the transformed strains, efficient biofuel production can be achieved.
KAIST researchers genetically modified a strain called Rhodococcus opacus and optimized the culture conditions of the strain to maximize the use of glucose metabolism to accumulate fatty acids, and a series of biochemical reactions to achieve high concentrations of hydrocarbons and fatty acid B Esters, and these substances are the main components of biodiesel.
According to Asian Scientist, a scientific news website, using this new method, the concentration of fatty acids, fatty acid ethyl esters and long-chain hydrocarbons transformed by bacteria can reach 50.2g / L, 21.3g / L and 5.2 g / L, respectively. Have the prospect of commercial production. In fact, as early as 2013, researchers used genetically modified E. coli to convert sugar into short-chain hydrocarbons, but the production concentration was only 0.58g / L, which was far less than the level required for commercialization.
Sang Yup Lee, the head of the KAIST research team, said that this technology utilizes lignocellulose, one of the richest resources on earth, and achieves the efficient production of fatty acids and biodiesel without relying on fossil fuels and animal and vegetable oils. . The results of this research will provide new opportunities for the petroleum industry that has long depended on fossil fuels.
The oil price network wrote that the emergence of this technology is likely to permanently change the field of biofuels. In order to achieve the climate goals set by the Paris Agreement, it is particularly important to reduce the use of fossil fuels, but so far, biofuels have not yet achieved the efficiency required for large-scale applications, and prices need to be reduced. However, this technological breakthrough may greatly push the balance towards a greener future. (Li Limin)
