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. ... -
Minimizing photooxidation in dairy products by tailor made light barrier properties in packaging materials
(PhD Thesis;2011:47, Doctoral thesis, 2011)Photooxidation is one of the major causes of food quality deterioration. Packaging is a common tool to protect against light and consequently prolong the shelf life of food. Transparent packaging materials are being widely ... -
Mitochondrial oxygen consumption and myoglobin redox stability in beef
(PhD Thesis;2012:14, Doctoral thesis, 2012)Myoglobin is the main pigment in meat and exists in three predominant states; deoxymyoglobin (DMb), oxymyoglobin (OMb), and metmyoglobin (MMb). The different myoglobin states are dependent on the production of mitochondrial ... -
Modern sour beer production : mixed fermentations with yeast and lactic acid bacteria
(PhD Thesis;2019:104, Doctoral thesis, 2019)Traditional sour beers are produced by spontaneous, mixed fermentations where numerous yeast and bacterial species are involved. One of the traits that separate sour beers from other beers is the high concentration of ... -
Modulation of gut microbiota by pre/probiotics and the potential health promoting outcomes for the host
(PhD Thesis;2016:42, Doctoral thesis, 2020-11-19)Gut microbiota is considered an organ that co-develops with the host throughout its life. The composition and metabolic activities of gut microbiota are subjected to a complex interplay of the host genetics and environmental ... -
Molecular mechanisms of pneumococcal fratricide
(PhD Thesis;2010:13, Doctoral thesis, 2010)The bacterium Streptococcus pneumoniae is endowed with the ability to take up naked DNA from the surroundings and recombine this DNA into the chromosome. This property, termed competence for natural genetic transformation, ... -
Multi-block methods for investigating consumer acceptance of food
(PhD Thesis;2013:67, Doctoral thesis, 2013)Today's researchers easily gather large amounts of data of different origin and type. In sensory and consumer studies the objective is the collection of data to better understand consumer behavior in the market. Statistical ... -
Multivariate analysis as a tool for understanding and reducing complexity of mathematical models in systems biology
(PhD Thesis;2011:34, Doctoral thesis, 2011)In the area of systems biology, technologies develop very fast, which allows us to collect massive amounts of various data. The main interest of scientists is to receive an insight into the obtained data sets and discover ... -
Natural and lactic acid bacteria fermentations of pastes of soybeans and soybean-maize blends : effect on nutritional quality, microbial diversity, food safety and consumer acceptance
(PhD Thesis;2014:84, Doctoral thesis, 2014)Traditional Malawian diets are predominantly maize-based and have been associated with widespread inadequate intakes of several nutrients. In addition to maize, legumes are an important source of protein and other nutrients ... -
Natural genetic transformation: development of a new genetic tool for Streptococcus thermophilus
(PhD Thesis;2010:16, Doctoral thesis, 2010)Lactic acid bacteria (LAB) have been used in fermentation of foods for hundreds or even thousands of years. During the last decade the genome sequences of a number of commercially important LAB species and strains have ... -
Natural transformation in Streptococcus thermophilus : Regulation autolysis and ComS*-controlled gene expression.
(PhD Thesis;2011:67, Doctoral thesis, 2011)Natural genetic transformation has been extensively studied in Streptococcus pneumoniae for generations, and much has been learned about this important phenomenon since its discovery by Frederick Griffith in 1928. In ... -
New methodologies in sensory and consumer research with preadolescents to guide product development of healthy, child-centred food
(PhD Thesis;2021:89, Doctoral thesis, 2021)Childhood obesity is one of the most serious public health challenges of the twenty-first century (WHO, 2018). In this context, finding ways to make the healthier food choices the preferred ones, can be a valuable contribution ... -
Non-target and suspect characterisation of organic chemicals of emerging concern in air and biota
(PhD Thesis;2020:42, Doctoral thesis, 2020)Persistent organic pollutants (POPs) and other regulated organic chemicals are being monitored in the environment to evaluate the effectiveness of regulations and conventions, spatial and temporal trends as well as a ... -
Novel aspects of the ecophysiology of denitrifying bacteria and their roles in N2O emissions
(PhD Thesis;2017:91, Doctoral thesis, 2017)Environmental bacteria are in general limited by nutrient availability, and as the conditions fluctuate rapidly and unpredictably they must adapt or they will not thrive. This requires fast and adequate sensing and ... -
Objective methods of classification for beef- and pork carcases as a basis for evaluation of carcase yield
(PhD Thesis;2024:13, Doctoral thesis, 2024)Yield within the meat industry refers to the ratio and weight of tissues from the carcase. Carcase classification gives each carcase grades that determine the price paid for the carcase. Two aspects are especially important ... -
Parameters and pedigrees in forensic genetics and statistics
(PhD Thesis;2017:46, Doctoral thesis, 2017)With the rapidly evolving DNA technology today, there is a constant need of more robust statistical methods for analyzing the data. The sequencing techniques are improving, making more genetic markers available, and we are ... -
Physiological features of aging in honey bees (Apis mellifera)
