Biofuels are a major focus of current development of new energy, but nowadays, the use of glucose contained in crops such as sugar cane and corn to produce bioethanol has led to the contradiction between biofuels and people’s struggle for food. The new issue of Britain’s “Biofuel Biotechnology†magazine reported that Singapore researchers have developed a new type of yeast that can convert xylose from plant waste into ethanol, thereby avoiding the contradiction between biofuels and people’s struggle for food.
Xylose is the second most abundant sugar in many plants, second only to glucose, and is present in a large amount in the branches of plants, which are usually not used as food and are often thrown away as waste. This advantage has prompted many scientists to study ways to convert xylose to ethanol.
However, in the conversion of xylose to ethanol, some of the yeast used in the past did not perform satisfactorily. Some yeasts can ferment xylose by fermentation, but they cannot be converted into ethanol; some yeasts can eventually produce ethanol, but the wood is decomposed by fermentation. The ability of sugar is not enough.
Researchers at Singapore Ngee Ann Polytechnic recently found a solution to this problem. They said in a recently published research report that a new type of yeast has been developed, which has a strong ability to convert xylose to ethanol and is expected to be used to make biofuels that are not competing with others.
Researchers at the Ngee Ann Polytechnic Institute in Singapore said that they genetically combined the genes of two different yeasts to produce a new type of yeast code-named ScF2. Experiments show that this new type of yeast can not only convert xylose into ethanol, but also has a high conversion efficiency, which exceeds the previously used yeast and has the potential for industrial application.
However, the researchers also stated that the yeast currently cultivated can only be regarded as a prototype strain, and further improvement is needed before it can finally be used in the large-scale industrial production of biofuels. (Reporter Huang Hao)
