  1. 1. Production of natural pigments from A. platensis grown on wastewater from local treatment facility.

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Author : Hana Faulds; [2023]
    Keywords : Cyanobacteria; pigments; microalgae; wastewater treatment; biotechnology; Technology and Engineering; Biology and Life Sciences;

    Abstract : Although microalgae have been considered for the biological treatment of wastewater since the 1950’s, their potential to efficiently remove pollutants from various streams remains largely untapped and is yet to be utilized at large scale. The production of algal biomass and extraction of high-value compounds has, however, become increasingly popular with large scale farms and biorefineries around the world producing many promising alternatives to petroleum-based products and processes.

  3. 2. Effect of temperature on plant growth and yield in everbearing strawberry Fragaria x ananassa, cv. Florentina

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Denis Butare; [2020]
    Keywords : strawberry; ever-bearing; temperature; flower mapping; photoperiod; flowering; plant development; yield;

    Abstract : Strawberry (Fragaria x ananassa Duch.) growth and yield are under genetic control and regulated by environmental factors such as temperature and photoperiod. The major objective of this study was to determine the effects of temperature under short-day treatment on plant development and flowering in the ever-bearing strawberry cv. READ MORE

  4. 3. Ljusets och mörkrets effekt på suggor och gyltor : reproduktion, produktion och välfärd

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Julia Carlsson; [2020]
    Keywords : ljusperiod; ljus intensitet; artificiell belysning; säsongsbunden infertilitet; laktation; grisning;

    Abstract : Det är av stor ekonomisk betydelse för lönsamheten i en intensiv grisproduktion att ha fungerande reproduktion och produktion av smågrisar. Syftet med denna litteraturstudie är att undersöka vilken effekt ljus och mörker har för suggor och gyltor i olika produktionsstadier samt inverkan av ljusperiod eller ljusintensitet. READ MORE

  5. 4. Time Constraint and Genetic (Phenotypic) Variation in Wing Shape in a Damselfly Along a Latitudinal Gradient

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Meagan Tunon; [2020]
    Keywords : Damselfly; time constraint; wing shape; morphology; climate change;

    Abstract : This degree project examined the effect of time constraint on wing shape and phenotypic variation in wing shape along a latitudinal gradient in the damselfly species Lestes sponsa. Fore and hind wings from individuals originating from three different latitudes: North (66°N), Central (59°N) and South (54°N) Europe were treated with their native temperature and photoperiod.

  6. 5. Bönsmyg i åkerböna : hur påverkas avkastning och skördekvalitet?

    University essay from SLU/Dept. of Ecology

    Author : Emma Ryding; [2020]
    Keywords : bönsmyg; Bruchus rufimanus; åkerböna; Vicia faba; avkastning; kvalitet;

    Abstract : Bönsmygen (Bruchus rufimanus) uppmärksammades som skadegörare i åkerbönor (Vicia faba) i Sverige 2008 och sedan dess har förekomsten och spridningen av den ökat snabbt. Det saknas kännedom om bönsmygens betydelse och hur den ska bekämpas vilket gör den till ett potentiellt hot i det svenska jordbruket. READ MORE
