This project concerns the use of thermophillic organisms to produce ethanol from all types of biomass. A recent improvement is that the thermophile converts all sugars to ethanol - unlike yeast which only converts C12 and C6 sugars. This gives the technology a target additional 30% of sugars to convert, thus increasing total output from the same volume of input biomass. This project is to test an alternative thermophile which has the potential to be more efficient than the current organism. This potentially improved organism has been genetically modified to make it more efficient in the production of ethanol from C5 sugars and from glycerol, and with less production of unwanted by-products. The project consists of operating this improved organism in a series of fermentation environments aimed at defining its optimum operating conditions, and thus establishing the fermenter design that would be enable this organism to be used in improved biorefining processes.

该项目涉及利用嗜热生物从所有类型的生物质生产乙醇。最近的一项改进是，嗜热菌可将所有糖转化为乙醇，而酵母则只能转化 C12 和 C6 糖。这使得该技术的目标是额外转化 30% 的糖，从而增加相同体积输入生物质的总产量。该项目旨在测试一种替代的嗜热生物，它有可能比现有生物体更有效。这种潜在改进的生物体经过基因改造，能够更有效地从 C5 糖和甘油生产乙醇，并且减少不需要的副产品的产生。该项目包括在一系列发酵环境中操作这种改进的生物体，旨在确定其最佳操作条件，从而建立发酵罐设计，使该生物体能够用于改进的生物精炼过程。
