Wiparat Siripong of the National Center for Genetic Engineering and Biotechnology in Thailand engineered the yeast Pichia pastoris to produce isobutanol from glucose and glycerol. The team diverted the amino acid intermedi...Wed, 17 Jan 2018 17:00:00 +0800Research and DevelopmentResearchers Develop Alcohol Tolerant Synechocystis sp. sp. PCC 6803 is an attractive organism for the production of alcohols. However, the produced alcohol is toxic to Synechocystis sp., hindering industrial applications. Hence, researchers want to engineer organisms with strong alcohol tolerance. Takuya Matsusako of Osaka University in Japan aimed to increase alcohol tolerance genes in S...Wed, 17 Jan 2018 17:00:00 +0800Research and DevelopmentStacking Multiple Traits for High Yield of Fermentable Sugars in Plant Biomass biofuels help decrease dependency on fossil fuels. To make biomass more suitable for biorefinery use, researchers need to better understand plant cell wall synthesis. Increasing the ratio of C6 to C5 sugars in the cell wall and decreasing the lignin content are two important targets in engineering of plants that are more suitable ...Wed, 17 Jan 2018 17:00:00 +0800Research and DevelopmentBangladesh Government Allows 5% Ethanol Blend Bangladesh legislation will now allow the use of ethanol with conventional fuels, however, it will not mandate production levels.The government will be allowing a 5% blend of bioethanol with octane and gasoline. This move is said to be a response to the interest of several producers to set up biofuel plants. Plant owners will have to first get ...Wed, 17 Jan 2018 17:00:00 +0800Policy and RegulationOverexpression of PdDUF231A Improves Cellulose Biosynthesis in Poplar function of Domain of Unknown Function 231-containing proteins (DUF231) is largely unknown. While previous studies have suggested that DUF231 proteins are related in O-acetyl substitution of hemicellulose and esterification of pectin, little is known about their function in woody plants. A study from Oak Ridge National Laboratory has revealed t...Wed, 17 Jan 2018 17:00:00 +0800Energy Crops and Feedstocks for Biofuels ProductionChinese Scientists Identify Important QTLs for Jatropha Fruit Yield demand for higher yield Jatropha curcas L. is rapidly increasing due to its potential in biofuel production. However, genetic analysis of Jatropha and molecular breeding for higher yield have been hindered by the few molecular markers available.Zhiqiang Xia of the Chinese Academy of Tropical Agriculture Sciences aimed to construct an ultrahigh-...Wed, 17 Jan 2018 17:00:00 +0800Energy Crops and Feedstocks for Biofuels ProductionUniversity of Tübingen Researchers Develop Process to Convert Whey into Biofuel of milk products produces a huge amount of wastewater in the factory. This wastewater, called "acid whey", cannot be fed to animals in large quantities due to its acidity. It is rich in organic material and must be treated or transported to farms for use as fertilizer.University of Tübingen scientists have recently developed a process th...Wed, 17 Jan 2018 17:00:00 +0800Biofuels ProcessingPseudomonas sp. Produce Bioflocculants for Microalgae Harvest has been developed as an effective method to harvest microalgae. However, the high production cost of bioflocculants makes it difficult to scale up. Haipeng Guo of Lakehead University in China aimed to develop low-cost bioflocculants using untreated corn stover and a biomass-degrading bacterium, Pseudomonas sp. GO2.Pseudomonas sp.
