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.

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.

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.
