Biofuels from poplar

Poplar Tree Genome Holds Promise of Breakthrough in Bio Fuel Research
The article discussed the importance of North American black cottonwood; Populus trichocarpa, being a prevalent topic of mercantile and environmental studies, was chosen as the first woody perennial plant to have its DNA sequence decoded by the DOE Joint Genome Institute because of its relatively compact genome, making it an ideal model system for trees. The article highlighted the examination of the first fulfilled DNA sequence of a black cottonwood tree that may set the foundation in using trees as a source of modern genre of biofuels such as cellulosic ethanol. The study is the outcome of four years of scientific and technical hard work under the leadership of the U.S. Department of Energy Joint Genome Institute or DOE JGI and Oak Ridge National Laboratory or ORNL and connecting the labors of thirty four institutions all over the world.

Biofuels may possibly offer a foremost solution to the ever-increasing energy requirements of a country such as the US by providing an ecologically welcoming substitute to imported oil. Alteration of plants for biofuels generation is one of the secrets to creating biofuels cost-effectively doable. This study, with the use of the latest genomic technologies, is an essential move towards emergent, realistic, biologically-based alternatives for gasoline and other fossil fuels. Biofuels are not only appealing for their promise to cut dependence on oil imports but also their decreased ecological influence. Biofuels give off less noxious wastes than fossil fuels such as gasoline. Moreover, poplar and associated plants are important managers of atmospheric carbon. Trees collect acquired carbon dioxide in their branches, leaves, stems, and roots. This inherent and natural course gives possibilities to enhance carbon elimination from the air by generating trees that successfully take and stock extra carbon underground in their roots and the soil. Further, bioenergy crops absorb again the carbon dioxide expelled when biofuels are used up, producing a cycle that is significantly carbon neutral.

Under best possible environment, poplars can add up a dozen feet of growth every year and achieve maturity in as few as four years allowing careful breeding for extensive sustainable plantation forestry. Such fast development together with alteration of the lignocellulosic part of the plant to ethanol has the capability to offer a renewable energy resource together with the decrease of greenhouse gases.
As compared to gasoline, ethanol from cellulosic biomass could spectacularly trim down secretions of the greenhouse gas carbon dioxide. Whereas burning gasoline and other fossil fuels intensifies atmospheric carbon dioxide concentrations, the photosynthetic generation of new biomass absorbs most of the carbon dioxide emitted when bioethanol is burned. The article also discussed the discovery of protein-coding genes that are very important in the biofuel evolution.

Poplar is the uttermost complicated genome to be sequenced and collected by a single public sequencing facility and is the third plant at the moment to have its genome fully sequenced and published.
The research into biofuels is concentrating on both plants and microbes in the attempt to find new biotechnology-based techniques of generating fuels from plant matter or biomass economically. Scientists foresee a future in which huge poplar farms could offer and supply steady quantity of tree biomass rich in cellulose that can be converted through specialized biorefineries into fuels like ethanol. There might also be a possibility that large amounts of biofuels can be generated from agricultural and forestry waste. Here is a link to the article
