Quality changes in lamb/sheep and beef meat with emphasis on its colour and flavour
(Doctoral thesis, 2018)The term known as meat quality is related to complex biochemical processes and changes that occur in the animal tissue before and after slaughtering. From an analytical point of view, the more factors describing meat quality ... -
Production of microbial protein from brown seaweed and spruce wood and its use as a novel feed ingredient in aquaculture
(PhD Thesis;2018:46;, Doctoral thesis, 2018)With the world’s rapidly expanding population, it is necessary to provide sustainable and nutritious food. Aquaculture is the world’s fastest growing food production sector and carries with it some major tradeoffs and ... -
Structural characterization of lignin and some side-products from steam-exploded woody biomass
(PhD Thesis;2018:91, Doctoral thesis, 2018)The main objective of this thesis was to make a platform of libraries for characterization of lignin and other side-products after steam-explosion. The complete and effective utilization of renewable biomass will be ... -
Spread and persistence of antibiotic resistance genes in the honeybee gut microbiota
(PhD Thesis;2018:26, Doctoral thesis, 2018)Bacteria residing in the gut – the gut microbiota (GM) – are important for host health. Several parallels between the human and honeybee GM exist: i) the GM is host specific (core microbiota), ii) age dependent development ... -
Regulation of expression, purification and structural determination of the cross-wall splitting protein PcsB in Streptococcus pneumoniae
(PhD Thesis;2015:8, Doctoral thesis, 2018-04-24)The human pathogen Streptococcus pneumoniae causes approximately 1.6 million deaths per year. Hence, it is of great concern that the bacterium`s resistance against antibiotics has increased dramatically in recent decades. ... -
A study of human chitinases with respect to the importance of surface exposed aromatic residues and carbohydrate-binding modules in substrate degradation and role in inflammations
(PhD Thesis;2015:63, Doctoral thesis, 2018-05-03)Chitin is an insoluble, linear polymer consisting of β-1, 4-linked N-acetyl-glucosamine units tightly packed in a crystalline structure. It is the second most abundant polysaccharide in nature, after cellulose, with an ... -
Health communication with adolescents and young adults to promote healthy eating
(PhD Thesis;2016:30, Doctoral thesis, 2018-05-03)Enhancing health communication with adolescents and young adults for health promotion, including a healthier diet, is essential. Nutrition labeling, applications (apps), and school environment are three channels for health ... -
Gene regulation and the emergence of phenotypes – a network approach
(PhD Thesis;2016:52, Doctoral thesis, 2018-05-03)The emergence of complex traits in living organisms has been of interest to biologists since the early days of biology. Domestication and breeding has resulted in the most remarkable transformations, such as the grass ... -
Linear multiresponse models : theoretical developments and applications in porcine
(PhD Thesis;2016:34, Doctoral thesis, 2018-05-03)The main topic of this PhD–thesis is how to minimize the prediction error for multi–response linear regression models. Two different applications are analysed, (i) bivariate response with missing data and (ii) image analysis ... -
Biochemical investigation of catalysis by lytic polysaccharide monooxygenases
(PhD Thesis;2016:69, Doctoral thesis, 2018-05-04)Lytic polysaccharide monooxygenases (LPMOs) are copper-dependent enzymes that catalyze the oxidative cleavage of glycosidic bonds in the presence of dioxygen and an external electron donor. Currently, these enzymes are ... -
The first stereoselective syntheses of (all-Z)- hentriaconta-3,6,9,12,15,19,22,25,28-nonaene and obscuraminol A, two polyunsaturated natural products
(PhD Thesis;2015:75, Doctoral thesis, 2018-12-19)The research described herein focuses on stereoselective synthesis of some Z-polyenoic natural products, making them available for biological studies. The objectives of the study can be subdivided into three parts integrated ... -
Better understanding of the relation of the dynamic sensory perception of solid and semi solid foods with consumers’ preferences and their perception of satiety
(PhD Thesis;2019:5, Doctoral thesis, 2019)Nowadays, overweight and obesity has been recognized as one of the main reasons that leads to many non-communicable diseases such as diabetes, high blood pressure, cardiovascular disease and in some cases cancer. Therefore, ... -
Applied and fundamental perspectives on brown-rot decay mechanisms
(PhD Thesis;2019:14, Doctoral thesis, 2019)Woody biomass is an important material for the growing bioeconomy, and has gained significant attention as a feedstock for second-generation biorefineries. Wood has traditionally been used as a building material for ... -
Evolution of gene expression following the whole genome duplication in salmonid fish
(PhD Thesis;2019:53, Doctoral thesis, 2019)Whole genome duplication (WGD) is a rare mutational event that provides additional duplicates of all genes in the entire genome, resulting in functional redundancy. This redundancy leads to relaxation of selective constraints ... -
Discovery and characterization of bacterial enzymes for processing of lignocellulosic biomass
(PhD Thesis;2019:62, Doctoral thesis, 2019)Utilization of non-edible biomass as a source of renewable carbon can assist the transition to a sustainable bioeconomy. Such biomass includes non-edible plant materials commonly referred to as lignocellulose. Lignocellulose ... -
