Isolation of cellulolytic enzymes using a metagenomic approach.

Kemp, Johan. January 2010 (has links)
M. Tech. Biotechnology. / Fossil fuel is a finite energy source which produces harmful by-products when used for combustion. A possible alternative is bio-fuel, preferably made from non-food cellulosic plants, such as bagasse or wood. Currently, there are some commercial enzymes which degrade cellulose, but there is room for improvement in both rate and sugar yield. The sugars derived from cellulose degradation are fermented to produce fuel-ethanol. This study utilized metagenomics to create a library containing environmental microbial DNA isolated from the rumen of cows. The aim of this study was to isolate local cellulolytic enzymes, more suited to the native environment and plant material, for potential use in the bio-fuel industry.

Energideklaration av flerbostadshus

Klang, Martin, Fogelberg, Claes January 2007 (has links)
In the year 2002 the European Union decided on a new directive according to the energy use in buildings. The outcome of this direction is a proposition from the Swedish government on the outlines of a new law in the field of energy use in buildings. The date that the law will be applied is the first of October 2006. In the future al real estate owners must be able to show an energystatement over the real estate. This project contains cooperation with HFAB a local real estate company where two buildings are analyzed according to their energystatement. The data from the analyzed buildings together with theoretical studies in the field of energy use in buildings resulted in conclusions according to the strategic ways to implement an energystatement over a building.
