This book was released on 2006 with total page 56 pages. Available in PDF, EPUB and Kindle. 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 2012-05 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study was conducted for the production of cellulase enzyme through liquid state bioconversion of palm oil mill effluent (POME) by filamentous fungi and characterization of the produced enzyme. Several experiments such as selection of filamentous fungi, optimization of media and process parameters, development of the separation/purification conditions for ultra-filtration, characterization and evaluation of purified cellulase enzyme through hydrolysis of oil palm empty fruit bunches (EFB) were carried out to achieve the entire objectives of the study. The results on isolation indicated that among the strains isolated, the strains IBPC108R, IBEC302B and IBEC305B gave the highest FPAse activity (0.3 U/ml) after 2 days of fermentation and IBEC302B showed the highest CMCase activity (0.42 U/ml) after 3 days of fermentation. Among the laboratory stocks, Aspergillus IBO-102MNB, gave the highest FPAse activity (0.28 U/ml) and Aspergillus IBO-103MNB gave the highest CMCase activity (0.62 U/ml) after 2 days of fermentation. Among the strains tested, the Trichoderma reesei RUT C-30, a commercial
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.

This book was released on 2019-03-01 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world population is expected to increase exponentially within the next decade, which means that the food demand will increase and so will waste production. There is a need for effective food waste management as wasted food leads to overutilization of water and fossil fuels and increasing greenhouse gas emissions from the degradation of food. Global Initiatives for Waste Reduction and Cutting Food Loss explores methods for reducing waste and cutting food loss in order to help the environment and support local communities, as well as solve issues including that of land space. Covering topics that include food degradation, enzymes, and microorganisms, this publication is designed for policymakers, environmentalists, engineers, government officials, researchers, scientists, academicians, and students.
Download or read book Cellulolytic Hydrolysis of Empty Fruit Bunch EFB of Oil Palm written by J. Kader and published by . This book was released on 1992 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrolysis of EFB was studied using crude enzyme from Aspergillus terreus SUL-1 as well as commercial enzyme from Trichoderma reesai and Aspergillus niger. Hydrolysis was performed at 50 C but sugar yield dropped significantly when commercial enzymes of T. reesei was used and the hydrolysis time extended beyonf 24 hrs. Low sugar yield was obtained from the hydrolysis of EFB. Glucose concentrations of 0.25 % and 0.5 % caused significant inhibition on the crude enzyme. Glucose was found to be a competitive inhibitor, with a Ki value of 3.33 mM when x-cellulose was used as a substrate.Contrary to the results with crude enzyme, glucose inhibition was found to have little effect on the commercial enzymes.

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.

This book was released on 2018-03-08 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Project Report from the year 2018 in the subject Biology - Micro- and Molecular Biology, grade: 0, , language: English, abstract: Cellulose is one the most abundant carbon sources present on the earth. In the book, the author reported on production optimization and characterization of cellulolytic enzymes by thermophilic bacteria. Various adaptation strategies adapted by thermophilic bacteria are also discussed along with. The thermophilic bacterial strain produced cellulase in the CMC broth, pH 7 containing 0.5% peptone, 0.5% malt extract, 0.2% ammonium sulphate, 0.2% ammonium nitrate and 0.2% NaCl at 50 ̊C. Interestingly, the bacteria could not grow at 37 ̊C, confirming its thermophilic nature. Further, the cellulase was characterized after getting partially purified by ammonium sulphate precipitation method. The partially purified cellulase may be employed to hydrolyze agricultural wastes to produce bioethanol, i.e. biofuels. Thus, the present research may help solve issues of crisis of renewable energy as well as environmental pollution.
