Mannan-hydrolysis by hemicellulases: enzyme-polysaccharide interaction of a modular beta-mannanase

The enzymatic degradation of plant polysaccharides is a process of fundamental importance in nature which involves a wide range of enzymes. In this work, the structure and function of hemicellulose-degrading enzymes was investigated. The focus was on a beta-mannanase (TrMan5A) produced by the filamentous fungus Trichoderma reesei. This enzyme is composed of a catalytic module and a carbohydrate-bi

I litteraturens mittfåra. Månadens bok och svensk bokmarknad under 1970-talet

Popular Abstract in Swedish Föreliggande avhandling, I litteraturens mittfåra, behandlar bokmarknad, bokklubbar och litteraturen under 1970-talet i Sverige. Bakgrunden till undersökningen är de radikala förändringar som skedde på den svensk bokmarknaden efter den genomgripande avregleringen av handeln med böcker 1970. Bokklubbarna växte från att inneha en marknadsandel på 9% 1970 till att ha 30% aThe present dissertation, I litteraturens mittfåra, deals with book trade, book clubs, and the fiction prose of the 1970s in Sweden. The background to the study is the radical change in Swedish book trade through a far-reaching deregulation of the trade in 1970. The book clubs expanded from a position where they held a 9% share of the market in 1970 to a market share of 30% in 1980.And the specifi

Optical properties of human whole blood - Changes due to slow heating

Optical properties of human whole blood were measured in vitro, at 633 nm with a double integrating sphere set-up, The blood was kept at constant flow through a flow cell while slowly heating the blood from approximately 25 degrees C to 55 degrees C in a heat exchanger, The results show a small but distinct decrease in the g-factor of 1.7 +/- 0.6\% and a similar increase in the scattering coeffici

Industrial challenges in the use of Saccharomyces cerevisiae for ethanolic fermentation of lignocellulosic biomass

Popular Abstract in English The production and use of bioethanol can help reducing the dependency on oil, and also represents a renewable source of energy. Bioethanol can be obtained from biomass such as agricultural and forest residues, after appropriate pretreatment and fermentation. This thesis addresses some of the challenges that must be overcome for the production of ethanol from biomass to The sustainable production of ethanol from lignocellulosic biomass requires the combination of efficient hydrolysis and complete fermentation of all the monomeric sugars present in the raw material. The present work was aimed at tackling some of the major challenges that will be encountered in commercial-scale ethanol production using Baker’s yeast, Saccharomyces cerevisiae, the preferred microorg

Association of Amphiphiles and Polyelectrolytes with DNA

DNA- cationic amphiphile and DNA-cationic polymer systems were studied with respect to the intermolecular interactions, as well as structure and stability of formed complexes. The thesis is divided in two parts: one section is a summary and the other section contains five papers. The summary is organized as follows; Chapter 2 gives an overview on the behavior of polyelectrolytes in solutions with

Consuming work and managing employability: Studentsʼ work orientations and the process of contemporary job search

Unemployment and precarity have become key features of 21st century work. Employability is presented as a solution to these issues. Individuals are exhorted to manage their employability, in order to be able to exercise choice in the labour market. While employability is individualsʼ responsibility, governments, employers and educational bodies simply provide opportunities for its development. Hig

The role of the recording studio

The transformation from analogue to digital recording techniques has not only changed the ways of working for the studiotechnician, but affects the musician in the way he thinks about performance and sound, and therefore also his actual performance. The signal processing and the staging of the singing voice in the studio is both influenced by, and influences the estethics of popular song performa

Får det lov att vara en dammsugare?

Inom försäljning av avancerade tekniska produkter och tjänster finns en relativt klar konsensus om vissa principer. Framför allt råder det enighet om att förståelsen av kundnyttan kommer i första hand. Man måste se processen från kundens perspektiv, och det måste finnas en klar och lättförståelig nytta för kunden. När det gäller god undervisning råder inte samma uppenbara konsensus. Det är inte sj
