Download or read book A Filter Paper Assay for Low Cellulase Activities and the Cultivation of Trichoderma Reesei on Acid Whey and Sweet Whey Permeate written by Tor Soren Nordmark and published by . This book was released on 1993 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The traditional filter paper assay for saccharifying cellulase originally described by M. Mandels et al (1976) has been modified to make possible low activity determinations of Trichoderma cellulases. The enzymatic activity appears to decline during a prolonged incubation period if no precautions have been taken. By means of adding bovine serum albumin and potassium chloride as protein stabilizers and sodium azide as an antimicrobial agent filter paper activities in the range from 0.02 to 0.37 (IUPAC assay, 1987) can be estimated by extending the incubation time up to 20 hours. Filter paper activity values obtained by this method may be compared to those obtained by the IUPAC assay by using a conversion factor from 1.4 to 1.7. Acid whey and sweet whey permeate have been investigated as media for growth and metabolite production by Trichoderma reesei QM 9414 using shake flask cultures and spore inocula. In the case of acid whey the mycelial growth after 2 weeks is 13 mg dry weight /ml substrate. The specific growth rate is 0.29/day. The fungus appears to metabolize the whey protein the first 2 weeks. The alkalinity of acid whey rises continuously over a three week period up to a pH of 8.5. In the case of whey permeate the maximal mycelial weight gain is 4.4 mg/ml which appears after 8 days. A rise in net soluble protein level comes after 3-5 days and reaches a maximum value of 0.23 mg/ml after 2 weeks. The pH of whey permeate rises continuously to 7.5 after 3 days and then slowly declines. The net production of cellulases is low on both media. Dilution 1:6 of the acid whey, supplementation with ammonium sulfate and pHadjustments did not enhance the production of cellulases. Acid whey supports a significant growth and sweet whey permeate shows potential for extracellular protein production. A literature review surveys the composition and uses of acid whey, environmental aspects of whey wastes, the fungus Trichoderma reesei, the mode of action of the Trichoderma reesei cellulase system and the structure of cellulose in cotton and wood.

Download or read book Clostridia written by Nigel P. Minton and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: To the uninitiated, the genus Clostridium is likely more to be associated with disease than biotechnology. In this volume, we have sought to remedy this misconception by compiling aseries of chapters which, together, provide a practically-oriented handbook of the biotechnologie potential of the genus. Clostridium is a broad grouping of organisms that together undertake a myriad of biocatalytic reactions. In the first two chapters, the reader is introduced to this diversity, both taxonomically and physiologically. In the following chapter, the current state of genetic analysis of members of the genus is reviewed. The remaining chapters concentrate on specific, exploit able aspects of individual Clostridium species-highlighting their range of unique capabilities (of potential or recognized industrial value), particu larly in the areas of biotransformation, enzymology, and the production of chemical fuels. Fittingly, the final chapter demonstrates that even the most toxic of the clostridia can be of therapeutic value. The contributors to this volume reflect the trans national interest in Clostridium, and we are indebted to each of them for making this volume possible. We particularly wish to acknowledge the contributions, both to this volume and to microbiology in general, of Dr. Elizabeth Cato, who, sadly, died shortly be fore publication ofthis volume. Finally, we would like to join the authors in recommending closer and wider consideration of the attributes and capabilities of this genus.

Download or read book Biofuel Production Technologies Critical Analysis for Sustainability written by Neha Srivastava and published by Springer Nature. This book was released on 2020-03-23 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Production and utilization of sustainable energy toward maintaining a clean environment is a major challenge. At the same time, the continued depletion of fossil fuels and the global dependency on non-renewable fuels is a chief concern. Moreover, the long-term economic and environmental issues associated with the high utilization of fossil fuel, such as global warming, are also important, particularly in the context of the predicted increase in the global population to around 5 billion by 2050. In recent years, researchers have been investigating alternative, renewable fuels to replace fossil fuels. Of the various options, biofuels are especially attractive due to their low production costs and the fact that they are pollution free. Also known as transportation fuels, their energy is derived from biological resources or through the biological processes. Biofuels such as biohydrogen, biomethane, biogas, ethanol and butanol offer a number of advantages and can be economically produced from cellulosic biomass. As such, they can play a vital role in sustainably meeting future energy demands. Biofuels have the potential to become a global primary energy source, offering significant reductions in greenhouse gas emissions as well as opportunities to increase economic and social development in rural communities and reduce the problems associated with waste disposal. However, low yields and lack of process technology are some of the aspects that need to be addressed. This book offers an overview of existing biofuels and the technologies to solve the problems associated with their practical implementation. Evaluating the biofuel options and discussing the opportunities and risks in relation to resources, technologies, practices, markets and policy, it provides insights into the development of economically viable bioenergy industries.

Download or read book Biomass Conversion written by Chinnappan Baskar and published by Springer Science & Business Media. This book was released on 2012-05-08 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: The consumption of petroleum has surged during the 20th century, at least partially because of the rise of the automobile industry. Today, fossil fuels such as coal, oil, and natural gas provide more than three quarters of the world's energy. Unfortunately, the growing demand for fossil fuel resources comes at a time of diminishing reserves of these nonrenewable resources. The worldwide reserves of oil are sufficient to supply energy and chemicals for only about another 40 years, causing widening concerns about rising oil prices. The use of biomass to produce energy is only one form of renewable energy that can be utilized to reduce the impact of energy production and use on the global environment. Biomass can be converted into three main products such as energy, biofuels and fine chemicals using a number of different processes. Today, it is a great challenge for researchers to find new environmentally benign methodology for biomass conversion, which are industrially profitable as well. This book focuses on the conversion of biomass to biofuels, bioenergy and fine chemicals with the interface of biotechnology, microbiology, chemistry and materials science. An international scientific authorship summarizes the state-of-the-art of the current research and gives an outlook on future developments.
