The increased development of unconventional resources recovery has dramatically changed the global energy landscape over the past two decades. Hydraulic fracturing combined with horizontal drilling, a key technology in recovering these resources, requires large freshwater volumes to fracture the...

Microbiota are ubiquitous in nature. Similarities as well as differences are present between microbiota in animals and fermentation systems. The aim of the PhD project was to investigate factors affects microbial ecology in rodent and sourdough models. To determine how compromised health of the...

The choice of the cereal substrate determines sourdough microbiota, however, the substrate-associated ecological factors for this phenomenon have not been elucidated. This study investigated the competitiveness of Lactobacillus sanfranciscensis LTH 2590, a wheat sourdough isolate, and four...

Anaerobic digestion (AD) is a sustainable method for treating high-strength wastewater while concurrently recovering biomethane. Nevertheless, factors such as low temperature and complex organic substrates can limit digestion kinetics, with hydrolysis and methanogenesis as the primary...

Protein fermentation by gut microbiota contributes significantly to the metabolite pool in the large intestine and may contribute to host amino acid balance. However, we have a limited understanding of the role that proteolytic metabolites have, both in the gut and in systemic circulation. A...

Currently, non-food carbon sources are making a valuable contribution to development of the next generation of hydrocarbon-based renewable fuels and value-added products. As non-food carbon feedstocks with low or negative value, yellow and brown greases, as well as biosolids, can potentially be...

Siliciclastic sediments become biostabilized when benthic bacteria penetrate into the pore spaces and secure grains with filaments and extracellular polymeric substances, forming a microbial mat. The cohesive microbial cover changes typical sedimentary dynamics and leads to formation of diverse...

The direct epifluorescence method has been adapted for counting bacteria in the sometimes turbid water of the Athabasca River and this method has been used to quantify planktonic bacteria. Monthly samples over an annual cycle beginning in May 1976 showed this population ranged from 1 x 105 to 2...

Although viable microbial communities have been shown to exist beneath glaciers, the impact of glacial retreat on these communities and development of the resulting foreland ecosystem is not well understood. This study investigated how microbial communities respond to changing conditions brought...
