Download or read book Optimization for Cellulase Production by Aspergillus Niger written by Saranraj J. P. and published by LAP Lambert Academic Publishing. This book was released on 2012-04 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microorganisms bring about most of the cellulose degradation occurring in nature. In the present study, optimization for cellulase production by Aspergillus niger was investigated by using paddy straw as substrate.Cellulase enzyme was produced by the fungus extracellularly. Optimization of cellulase production was done by using various physical (Temperature, pH, Salinity and Incubation time) and chemical parameters (Carbon sources and nitrogen sources) which could influence the enzyme activity. Cellulase production was maximum at the temperature 20°C and minimum at 40ºC. The optimal pH for the cellulase production was observed maximum in 6.0 and minimum in 7.0. Cellulase production was maximum at 48 hours and minimum at 24 hours. Cellulase production was maximum with when fructose was used as a carbon source and minimum with sucrose. Cellulase production was maximum when Malt extract was used as a nitrogen source and minimum with yeast extract. The cellulase enzyme extract was partially purified and its protein fraction was stained with its molecular weight determination by using SDS-PAGE. It revealed two protein bands with the molecular weights of about 83 kD and 50kD.

Download or read book Approaches to Enhance Industrial Production of Fungal Cellulases written by Manish Srivastava and published by Springer. This book was released on 2019-04-26 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cellulase is a key enzyme of industrial interest and plays a crucial role in the hydrolysis of cellulose, a prime component of plant cell walls. Cellulase covers a broad area in the global market of industrially important enzymes and it is considered as the third largest industrial enzyme globally. Additionally, cellulase contributes about 20% of the total enzyme market globally because of its massive demand in various industries such as in biofuel production, pulp, paper, textile, food, and beverages, as well as in detergent industries. Among these, the demand of cellulase may become frequently selected in the commercial production of biofuels in the future and thus will further increase demand of cellulase in the biofuel industry. Because biofuel production is still not realized in a cost-effective, practical implementation due to its high cost (the higher cost of biofuels is due to higher production costs of enzymes), there is a need to introduce these types of approaches, which will help to lower the cost of enzyme production for developing overall economic biofuel production.

Book excerpt: This editor believes the public finally understands that bioenergy should be a critical new 39 component of our world’s future energy supply. While this new enlightenment might have 40 come from bioenergy’s environmentally friendly attributes and its renewable and sustain- 41 able nature, the reality is that the primary driver has been both the high cost of energy, 42 led recently by petroleum products, and the unique climatic changes such as local weather 43 events and reports of melting of ancient glaciers. I believe that much of the public under- 44 stands the primary cause of these changes is the growing demand for fossil fuels for heat- 45 ing and transportation needs driven by both population increases and dramatic economic 46 development around the globe. This increased demand, as well as global politics, has 47 impacted the costs for these energy products. At the same time, increased use of fossil fuels 48 has been liberating unprecedented levels of CO and other greenhouse gasses (GHGs) 49 2 that must be impacting the global climate. As a result, the world is looking for alternative 50 solutions. Renewable energy is one of the leading options as long as it is pursued in a sus- 51 tainable fashion. Of course, renewable energy has numerous sources, including wind, solar, 52 geothermal, ocean currents/tides, and bio-based energy. The latter category of renewable 53 energy is centered primarily on use of green plant matter, i. e.

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 Cellulase Production by Trichoderma Reesei Rut C30 written by Chi-Ming Lo and published by . This book was released on 2008 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the price of oil continues to increase and the concern over global warming heightens, finding alternative renewable sources of energy becomes more and more imperative. Considering the abundance of lignocellulosic biomass, the potential significance of its conversion to fuel such as ethanol has long been recognized. Ethanol production from lignocellulosic biomass requires the breakdown of the solid material to simple sugars that can be consumed by microorganisms. The breakdown of lignocelluloses includes the important step of hydrolyzing cellulose, which are [Beta]-1, 4 linked polymers of glucose, by a group of enzymes collectively termed cellulase. The cost of cellulase production profoundly influences the economics of the entire ethanol production process. Trichoderma reesei Rut C-30 is the most commonly used fungal strain for industrial cellulase production. With an overall goal of decreasing the cellulase production cost, this thesis work was focused on two topics: (1) investigation of the performance of different cellulase-inducing substrates in T. reesei Rut C-30 fermentation and (2) development of a more advanced model to describe the culture behaviors of T. reesei Rut C-30 grown on lactose-based media. The cellulase-inducing substrates investigated in this work included the acid-treated hydrolysate, lactose, and the sophorolipids produced by the yeast Candida bombicola. In addition to the above focused topics, the effects of culture conditions on cellulase production were also investigated. The acid-treated hardwood hydrolysates used in the study were prepared by a two-stage process, with different durations of boiling and acid concentrations. The results indicated that the inducing ability of the hydrolysates decreased with increasing boiling time (less oligomers). The observation was attributed to the lower amounts of inducing oligomers remaining after the longer boiling in acid. When compared with cultures growing on mixed carbon substrates of cellulose and glucose, the culture growing on hydrolysates showed a longer lag phase of about 24 hours (before the active cell growth began), but produced adequately comparable final cellulase activity. The study with lactose as an inducing substrate was conducted in both batch and continuous culture systems with lactose and other relevant substrates (glycerol, glucose and galactose) as the carbon source. Instead of direct ingestion, lactose is believed to be hydrolyzed by extracellular enzymes to glucose and galactose, which are then taken up by the cells. The study results indicated that glucose strongly represses the galactose metabolism: Cells started to consume galactose only after the glucose had been depleted. A mathematical model incorporating all important metabolic activities was developed to describe the culture behaviors. All of the experimental results obtained were used in model fitting to generate a set of best-fit model parameters. The study provided significant conceptual and quantitative insights to the lactose metabolism and cellulase production by T. reesei Rut C-30. This study was also the first to hypothesize and demonstrate the use of sophorolipids as the inducing substrate for cellulase production. A unique process for cellulase production using a mixed culture of T. reesei Rut C30 and Candida Bombicola growing on glycerol-based media was investigated. Hypothetically, the sophorolipids produced by C. bombicola were hydrolyzed to form sophorose, which then served as the inducer for cellulase production by T. reesei. Further study to optimize the sophorolipid-induced cellulase production process is recommended.
