Abstract:

Due to environmental challenges, depleting oil resources, rising cost of oil and instability in oil-producing countries, biofuel production has attracted a lot of attention in recent decades. Biobutanol is one of the biofuels showing the most potential as an alternative for partly replacing petroleum-based fuels. Both researchers and industrialists are currently working at developing an energy-effective process to produce biobutanol at a large scale. Acetone-butanol-ethanol (ABE) fermentation is the biological process of biobutanol production and Clostridia are the most common bacteria used to

Abstract:

Driven by the diminishing total reserve of fossil fuels and growing concerns about energy security and environmental issues, there is an increasing interest in developing microbial-based processes for the production of biofuel. As most natural fermentation processes do not yield desirable products at an economically viable scale, it is often required to genetically engineer, including deletion and/or insertion of necessary pathways to optimize yield or get new products. Thus it is essential to have the necessary genetic tools, and such was developed, to both improve and innovate upon existing

Abstract:

The future of biofuel production hinges on a cheap, readily available feedstock. In terms of resources available, lignocellulose is the most abundant renewable resource on the planet, available from a plethora of sources such as agriculture, forestry, industry and municipals, therefore presenting an attractive resource. Cellulose, hemicellulose and lignin are the three main constituents of lignocellulose. The viability of such a feedstock requires as much of these constituents being converted to product as possible and therefore requires the suitable candidate organism to achieve this. Hemicel

The global warming on earth has been obvious since the 1950’s. Fossil fuels have a big impact on the observed warming and it is time to replace them with more environmentally friendly fuels. Biobutanol has been proven to be a preferred substitute to fossil fuels. The yeast Saccharomyces cerevisiae is a potential butanol producer. A problem in the biobutanol production is that the product, butanol, is toxic to the producer.
