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 ... -
Dietary influence on intestinal microbiota and immune responses in mice : roles of high-fat diet and reactive oxygen species (ROS)
(PhD Thesis;2020:60, Doctoral thesis, 2020)The gastrointestinal tract harbors trillions of bacteria. Host and microbiota co-evolved in a mutualism relationship with a certain degree of dependency, where the host provides a nutrient-rich environment and benefits ... -
Functional insights into novel factors affecting cell division in Gram-positive bacteria
(PhD Thesis;2021:91, Doctoral thesis, 2021)The opportunistic pathogen Staphylococcus aureus is a major contributor to a range of different infections in human and animals that have become difficult to treat because of the rise of antibiotic resistant strains. New ... -
Tailoring microalgal biomass for food applications : fermented beverage as a case study
(PhD Thesis;2022:19, Doctoral thesis, 2022)Microalgae are renowned as super-foods due to their unique nutritional profiles; however, their applications to human nutrition are still limited to nutraceuticals and food supplements. This is likely due to factors such ... -
Studies of molecular determinants of virulence in Aliivibrio salmonicida and Vibrio anguillarum
(PhD Thesis;2021:58, Doctoral thesis, 2021)The arsenal of virulence factors possessed by a bacterium can determine its ability to infect the host and cause disease. Chitinases and chitin-active lytic polysaccharide monooxygenases (LPMOs) have been indicated to ... -
Taste sensitivity and food liking in preadolescent children
(PhD Thesis;2021:83, Doctoral thesis, 2021)Taste is a key factor in determining food palatability and affects food acceptance. Children have been reported to have different taste sensitivity perceptions, which may influence their food preferences. The main objective ... -
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 ... -
Production of yeast from spruce sugars and hydrolysates of protein-rich by-products as feed ingredient
(PhD Thesis;2019:60, Doctoral thesis, 2019)The biotechnological potential and food-grade nature of yeasts are evidenced by their rich history of application in food fermentations. Thus, yeasts have been recognized as a suitable microorganism for the production of ... -
Expanding the analytical toolbox for characterization of proteolytic reactions : advances in FTIR spectroscopy and classical methods
(PhD Thesis;2019:85, Doctoral thesis, 2019)Enzymatic protein hydrolysis is a well-established industrial process recognized for its potential to improve sustainability in food production by valorization of protein-rich byproducts from the food industry. Monitoring ... -
Kinetic investigations of the oxidative cleavage of oligomeric carbohydrates provide novel insights into the catalytic action of fungal lytic polysaccharide monooxygenases
(PhD Thesis;2021:61, Doctoral thesis, 2021)The lytic polysaccharide monooxygenases (LPMOs) are a recently discovered class of redoxactive mono-copper enzymes that catalyze the oxidative cleavage of glycosidic bonds in recalcitrant plant or chitin-based biomass, ... -
Dewatering of digested biomass
(PhD Thesis;2019:36, Doctoral thesis, 2019)The world’s population is increasing and as cities grow in population and area, efficient and safe handling of sewage is becoming increasingly important. Wastewater treatment generates two products; purified water and ... -
The microbial diversity of mesophilic starter cultures used in cheese production
(PhD Thesis;2017:96;, Doctoral thesis, 2017-11)For ages, humankind has preserved various foods by fermentation by lactic acid bacteria (LAB), and fermentation of milk to obtain cheese can be traced back to the domestication of cattle, at least seven millennia ago. ... -
Investigating evolution of gene regulation with crossspecies comparative transcriptomics
(PhD Thesis;2017:101, Doctoral thesis, 2017)An essential ability of all lifeforms is to regulate the activity of its genes. This ability is what allows multicellular organisms to generate hundreds of completely different cells despite having the same genome. It is ... -
Novel aspects of the ecophysiology of denitrifying bacteria and their roles in N2O emissions
