In the last 40 years, several scientific and technological advances in microbiology of the fermentation have greatly contributed to evolution of the ethanol industry in Brazil. These contributions have increased our view and comprehension about fermentations in the first and, more recently, second-generation ethanol. Nowadays, new technologies are available to produce ethanol from sugarcane, co...

Background The cyanobacterium Arthrospira platensis shows promise as a carbohydrate feedstock for biofuel production. The glycogen accumulated in A. platensis can be extracted by lysozyme-degrading the peptidoglycan layer of the bacterial cell walls. The extracted glycogen can be converted to ethanol through hydrolysis by amylolytic enzymes and fermentation by the yeast Saccharomyces cerevisiae...

Biofuel, a form of renewable fuel, has promising future, especially as the alternative fuel for transportation. Biofuel is usually blended with petroleum fuel and used in flex fuel engines. Since the characteristics of biofuel are quite different from those of the petroleum based fuel, it is very important to optimize the combustion properties for biofuel engines under different fuel blends. Th...

This research work focused on the production of biofuel from orange peels using Bacillus subtilis as a fermentor. The were collected Ekeukwu market and Ihiagwa fruit center, Owerri Nigeria, sun dried grinded manually to powder. sample was further fermented for 8days subtilis, after which it distilled 6 hours in order extract biofuel.Analysis ethanol compostion carried out gas chromatography.The...

BACKGROUND Sweet sorghum is a domesticated grass containing a sugar-rich juice that can be readily utilized for ethanol production. Most of the sugar is stored inside the cells of the stalk tissue and can be difficult to release, a necessary step before conventional fermentation. While this crop holds much promise as an arid land sugar source for biofuel production, a number of challenges must ...

BACKGROUND The greenhouse gas (GHG) emissions that may accompany land-use change (LUC) from increased biofuel feedstock production are a source of debate in the discussion of drawbacks and advantages of biofuels. Estimates of LUC GHG emissions focus mainly on corn ethanol and vary widely. Increasing the understanding of LUC GHG impacts associated with both corn and cellulosic ethanol will infor...

We calibrate the Center for Agricultural and Rural Development International Commodity Market model using 2019/20 marketing year crop data 2020 calendar livestock biofuel to project China's agricultural imports under six plausible policy scenarios focusing on ethanol, corn, pork from 2021 2030. Our baseline projection reflects current of relaxing tariff rate quota (TRQ) corn imposing ethanol wi...

BACKGROUND Future sustainable energy production can be achieved using mass cultures of photoautotrophic microorganisms, which are engineered to synthesize valuable products directly from CO2 and sunlight. As cyanobacteria can be cultivated in large scale on non-arable land, these phototrophic bacteria have become attractive organisms for production of biofuels. Synechococcus sp. PCC 7002, one o...

An environmental, climate mitigation rationale for research and development (R&D) on liquid transportation fuels derived from plants emerged among many scientists and engineers during the last decade. However, between 2006 and 2010, this climate ethic for pursuing biofuel became politically entangled and conceptually confused with rationales for encouraging greater use of plant-based ethanol th...

There has been a dramatic growth in the production of biofuels in recent times. Global biofuel production tripled between 2000 and 2007, and biofuels accounted for about 1.6% of global transportation fuel in 2012 (International Energy Agency). At the time of this writing, 2015, ethanol production is by far the greatest contribution by biotechnology to energy production, with revenue accounting ...
