21. Volatiles of Conifer Seedlings : Compositions and Resistance Markers
Sammanfattning : Pine weevils cause major damage to newly planted conifer seedlings in reforestation areas. However, recent findings indicate that small (“mini”) seedlings, planted at the age of 7-10 weeks, are gnawed less by pine weevils than the larger, conventionally planted seedlings. LÄS MER
22. Oxidation of Ketones: A (Chemo-) Enzymatic Approach Using Oxygenases and Hydrolases
Sammanfattning : Oxidation reactions are important in organic chemistry as well as in nature. In industry, oxidations are commonly used for the synthesis of chemicals and pharmaceuticals, however such processes have a number of limitations, they use chlorinated solvents, stoichiometric oxidation reagents, and in some cases the reagents that have risks of explosion during transportation and storage.

23. Formic and Levulinic Acid from Cellulose via Heterogeneous Catalysis
Sammanfattning : The chemical industry of today is under increased pressure to develop novel green materials, bio-fuels as well as sustainable chemicals for the chemical industry. Indeed, the endeavour is to move towards more eco-friendly cost efficient production processes and technologies and chemical transformation of renewables has a central role considering the future sustainable supply of chemicals and energy needed for societies.

24. From recovery boiler to integration of a textile fiber plant : Combination of mass balance analysis and chemical engineering
Sammanfattning : Modern chemical technology is an efficient tool for solving problems, particularly within the complex environment of the pulp and paper industry, and the combination of experimental studies, mill data and mass balance calculations are of fundamental importance to the development of the industry. In this study various examples are presented, whereby chemical technology is of fundamental importance. LÄS MER
25. An NADH-Coupled Biosensor for Engineering Redox Metabolism in Saccharomyces cerevisiae
Sammanfattning : Baker’s yeast, Saccharomyces cerevisiae’s potential in industrial biotechnology for producing valuable products e.g. biofuels, bulk chemicals, bio-flavours and pharmaceuticals is established. LÄS MER
