Introduction The production of acetone and butanol by means of solvent-producing strains of Clostridium spp. was one of the first large-scale industrial fermentation processes to be developed‚and during the first part of this century it ranked second in importance only to ethanol fermentation. The reason for the almost total demise of this fermentation in the early 1960s was the inability of the fermentation process to compete economically with the chemical synthesis of solvents. However‚ interest

produces a limited or no amount of waste and pollutant*. The next portion of this research deals with taking this sugar and converting it into butanol fuel via fermentation. This will be done by genetically modifying the metabolic pathways of‚ Clostridium beijerinckii‚ to convert the glucose (sugar) into high yields butanol fuel. The objective here is to perform gene deletion in an attempt to direct the metabolic pathways of the microbe in such a way where it will produce the highest yield of butanol

Vol 454j14 August 2008jdoi:10.1038/nature07190 REVIEWS Genomics of cellulosic biofuels Edward M. Rubin1‚2 The development of alternatives to fossil fuels as an energy source is an urgent global priority. Cellulosic biomass has the potential to contribute to meeting the demand for liquid fuel‚ but land-use requirements and process inefficiencies represent hurdles for large-scale deployment of biomass-to-biofuel technologies. Genomic information gathered from across the biosphere‚ including potential

Introduction The energy consumption grows year by year with the economical development of the countries such as China and Japan despite the boisterous events. With the ‘Arab Spring’ in 2011‚ energy market was shook in terms of both production and consumption of the oil with the loss of one of the suppliers‚ also the massive earthquake and tsunami that hit Japan coast caused immediate action for nuclear power and other fuels around the world. Due to those events‚ oil prices reached an all-time record

Bacteria are unicellular and ultra-microscopic organisms‚ yet they play an important role in nature. They are of tremendous importance to man. They play an important role in agriculture and medicine and are the basis of many industries. Some are beneficial to man directly or indirectly‚ others are very harmful as they cause various plant and animal diseases. Bacteria are considered as our friends and foes due to their beneficial and harmful activities. Their economic importance can be studied under

Bacterial Fermentation Secondary article Article Contents Volker Mu¨ller‚ Ludwig-Maximilians-Universita¨t Mu¨nchen‚ Munich‚ Germany . Introduction Under anaerobic conditions‚ in the dark and in the absence of electron acceptors‚ organic compounds are catabolized by strictly anaerobic or facultatively anaerobic bacteria by internally balanced oxidation–reduction reactions‚ a process called fermentation. In fermentation‚ the organic compound serves as both electron donor and acceptor‚ and adenosine

One type of HAI which is caused by the germ Clostridium Difficile or C-Diff. In 2015 it was estimated almost half a million infections in the United Ststes‚ and 29‚000 died within 30 days of the initial diagnosis. Those most at risk are older adults‚ who take antibiotics and also get medical care. The CDC provides guidelines and tools for the healthcare population to help
