Adhesion av mikroorganismer till lignocellulosa

The aim of the project was to develop a method to investigate differences in adhesion of microorganisms to materials that contains lignocellulose. The method was tested on a gram-positive (Micrococcus lutea) and one gram-negative (E-coliJM109) bacteria.The study was begun by cultivation of the two microorganisms. The cultivation was done to calculate the generation times of the bacteria and to obtain growth curves. Cells from these cultivations were also frozen (-70ºC) and later used for inoculation.At STFI-Packforsk AB the total charge on the mass was measured and later a conductivity titration on the mass was executed as well, all to find out more about the different properties of the mass. Properties that in a later part of this study could possibly be linked to the adhesion of cells to the pulp.

EU och pengarna : en undersökning om hur den översiktliga planeringen i två svenska strategiska regioner påverkas av Europeiska regionala utvecklingsfonden

The European Union is a 60 year long collaboration between the European countries. It was born from the intention to ease trade and thereby reassure peace. Within the 60 years EU has functioned it has developed and expanded further. In 1952 it evolved around the trade of coal and steel between six countries, today it includes 27 nations and oversees a large number of topics such as foreign affairs, a common currency and regional politics. EU has grown at several times, the latest expansion was the largest where 12 new countries became members. The unions of countries that only 60 years ago were at different sides of a world war can be considered an accomplishment.
