Book excerpt: Cellulases are important in industrial enzyme which is a main part in industrial process such as in bio-bleaching and bioethanol production. Nowadays, our country encourages the production of bioethanol from the biomass material such as oil palm empty fruit bunch fiber in order to enhance the resources of ethanol production and reduce the cost.In this project, oil palm empty fruit bunch fiber was used as a substrate for the production of cellulase enzyme by Aspergillus terreus SUK-1. In order to enhance the cellulase production, pretreatment on substrate are performed with different type of methods. Comparison results of cellulase enzyme production are determined between the substrate which is pretreated with acid and alkaline pretreatment. The effect of steam explosion on the substrate also was identified in shaking flask fermentation. From the experimental work, it was found that the highest xylanase and carboxymethylcellulase activity was in fermentation of acid treated substrate than alkali treated substrate and untreated substrate It also found that by autoclaved the substrate with chemicals produced the highest cellulase enzyme with value 0.167836U/ml for xylanase and 0.3534U/ml for carboxymethylcellulase.

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.

This book was released on 2013-11-26 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental sustainability and development is of critical importance. Technological advances in the production of new energy sources are making their way into our lives in more and more depth every day. However, there is an urgent need to address the technological challenges and advancement of the various chemical and bio-processes to maintain the dynamic sustainability of our energy needs. Toward that end, an attempt is being made to look at recent advances, key issues still faced and where possible, offer suggestions on alternative technologies to optimize sustainable processes. Still considered a new area of science, energy sources themselves are still being 'discovered'...meaning, what is financially viable in the current marketplace is changing. For example, energy from plants has not been financially viable in the past because of the high cost of growing, harvesting, breaking down cell walls, disposal of waste products, etc. Materials used to derive energy from sustainable resources is changing, making previously high-cost processes more efficient. It is crucial that the industry as a while works in tandem to develop crops that new technological advances make financially feasible. This book will cover recent advances in the chemicals, bioprocesses and other materials used in growing and extracting energy from sustainable products. Membrane/cell wall digestion issues will also be covered as well as recovering mamixal amounts of energy from sources to limit waste. Finally a section on safety and control will be presented with has been poorly covered in other publications.
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.
