  1. 11. The effect of imperfect resource conversion and recurring perturbations on byproduct cross- feeding chains in digital communities

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Filippa Frejborg; [2021]
    Keywords : byproduct cross-feeding; cross-feeding interactions; digital evolution; digital organisms; gut microbiome; recurring perturbations; resource conversion;

    Abstract : The gut microbiome plays a vital role in human health. Disturbances of this microbial system is associated with diseases such as obesity and inflammatory bowel disease. In populations of microbial species, many organisms partake in byproduct cross-feeding interactions, where byproducts from one organism are consumed by other microbes. READ MORE

  3. 12. Milk from minor dairy species : Composition, processing and microbial aspects

    University essay from SLU/Department of Molecular Sciences

    Author : Simon Tobias Höxter; [2021]
    Keywords : minor dairy species; equine milk; horse milk; mare milk; donkey milk; ; red deer milk; camel milk; reindeer milk; moose milk; dairy products;

    Abstract : Milk plays an important part of the diet all around the world and 99 % of the milk consumed by humans comes from bovine, buffalo, sheep, and goat. In addition, some other species are used for milk production, so called minor dairy species. This literature review focused on six minor dairy species, i.e. READ MORE

  4. 13. Comparison of Different Wood Types for Use as a Porous Substrate in Denitrifying Woodchip Bioreactors

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Erica Erikson; [2021]
    Keywords : denitrification; woodchip bioreactor; column experiments; denitrifikation; träflis-bioreaktor; kolonnexperiment;

    Abstract : Explosives used in the mining industry release nitrate into the environment, causing concerns for the water quality in local river-systems. One way of reducing the nitrate loading into the environment is through a woodchip bioreactor. READ MORE

  5. 14. Sedimentary Factories and Ecosystem Change in the Triassic-Jurassic Boundary Interval : Insights from the Skåne Area (Southern Sweden)

    University essay from Uppsala universitet/Paleobiologi

    Author : Gustav Nesset Mattsson; [2021]
    Keywords : CAMP; microbial structures; End-Triassic extinction event; sedimentary structures; MISS; Triassic-Jurassic boundary; CAMP; mikrobiella strukturer; Trias-jura-utdöendet; sedimentära strukturer; MISS; Trias- juragränsen;

    Abstract : The End-Triassic Extinction (ETE) has long remained one of the lesser known among the so-called “Big Five”. There exist several hypotheses regarding the probable cause of this extinction, which can mainly be divided into  events of  a decline in the rate of diversification  in the late Triassic contra a sudden and significant extinction event.

  6. 15. The metagenomes of root nodules in actinorhizal plants : A bioinformatic study of endophytic bacterial communities

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Ellen Fasth; [2021]
    Keywords : Actinorhizal plants; Frankia; endosymbiosis; root nodules; metagenomes; bioinformatics;

    Abstract : Actinorhizal plants are in symbiosis with the nitrogen-fixating soil bacterium Frankia, which forms nodules in the plant root. However, several studies also report other endophytic bacteria appearing in the nodules, but their function and interaction with the host plant or Frankia is not yet understood. READ MORE
