Biotechnology for the Future

One area that has attracted much attention is the use of cell factories for the production of a wide range of chemicals. This area illustrates very well the definition of biochemical engineering , and it has therefore been chosen as the focus of this volume. The use of cell factories for production of chemicals dates back to the production of penicillin, ethanol, acetone–butanol, glycerol and further to enzymes and other antibiotics. All these products were traditionally produced by cell factories that naturally produce these compounds. With the introduction of genetic engineering it has,This volume therefore contains chapters on concepts of metabolic engineering on detailed modeling of cellular systems

Biotechnology for Fuels and Chemicals : The Twenty-Ninth Symposium

In Biotechnology for Fuels and Chemicals: The Twenty-Ninth Symposium, leading US and international researchers from academia, industry, and government exchange cutting-edge technical information and update current trends in the development and application of biotechnology for sustainable production of fuels and chemicals. This symposium emphasizes advances in biotechnology to produce high-volume, low-price products from renewable resources, while improving the environment. The major areas of interest include advanced feedstock production and processing, enzymatic and microbial biocatalysis, bioprocess research and development, opportunities in biorefineries, and commercialization of biobased products. International and domestic progress on producing liquid biofuels, especially ethanol and biodiesel, is highlighted, and related topics, including bioseparations and optimal integration of biochemical and thermochemical conversion technologies, are featured.

Biofuels, Solar and Wind as Renewable Energy Systems : Benefits and Risks

With shortages of fossil energy, especially oil and natural gas, and heavy biomass energy use occurring in both developed and developing countries, a major focus has developed worldwide on renewable energy systems. Renewable energy systems include wind power, biomass, photovoltaics, hydropower, solar thermal, thermal ponds, and biogas. Currently, a heavy focus is on biofuels made from crops, such as corn, sugarcane, and soybeans, for use as renewable energy sources. Wood and crop residues also are being used as fuel. Though it may seem beneficial to use renewable plant materials for biofuel, the use of crop residues and other biomass for biofuels raises many concerns about major environmental problems, including food shortages and serious destruction of vital soil resources.

Biofuels

In line with the current focus on a sustainable economy, bioethanol and other biofuels have received tremendous attention, making many headlines. Being produced in steadily growing volumes has made it necessary to consider production of biofuels from renewable raw materials that are not currently used. Therefore, the production of biofuels is at the gateway of moving from traditional raw materials to others such as lignocellulosic materials. However, sucha transfer requires new production processes that are economically feasible.This volume addresses and discusses the current status of biofuels, covering aspects from enabling technologies to different technology and processes options, as well as economical and policy perspectives.

Biodiesel : A realistic fuel alternative for diesel engines

Environmental and political concerns are generating a growing interest in alternative engine fuels such as biodiesel. Biodiesel is a renewable energy source produced from natural oils and fats, which can be used as a substitute for petroleum diesel without the need for diesel engine modification. In addition to being biodegradable and non-toxic, biodiesel is also essentially free of sulfur and aromatics, producing lower exhaust emissions than conventional gasoline whilst providing similar properties in terms of fuel efficiency.

A Biomass Future for the North American Great Plains : Toward Sustainable Land Use and Mitigation of Greenhouse Warming

The Great Plains of North America is a major global breadbasket but its agriculture is stressed by drought, heat spells, damaging winds, soil erosion and declining ground water resources. This book explores the possibility that the ecology and economy of the Plains region (and similar regions) would benefit from the introduction of perennial biomass crops. Biomass production and processing on the Plains (possibly aided by genetic engineering) would partially restore a perennial vegetative cover and create new employment opportunities. Biomass also offers a means of reducing fossil fuel use, providing fuel to local power plants and a feedstock for production of cellulosic ethanol, a gasoline substitute. Interest in biofuels is growing rapidly in public, political and business circles with rising fossil fuel prices and because of a growing recognition of the need for energy independence in petroleum importing countries.
