  1. 1. The potential to use rhizobacteria within agricultural innovations instead of chemical inputs : taking quality and quantity of the crop into consideration

    University essay from SLU/Dept. Of Plant Biology

    Author : Ida Quisth; Isabella Ulfsparre; [2024]
    Keywords : Biocontrol; Biofertilizer; Biopesticide; Biostimulant; Plant growth promoting rhizobacteria; PGPR; Quality; Rhizosphere Microbiome; Yield;

    Abstract : Plant growth promoting rhizobacteria (PGPR) are soil bacteria that occur naturally, colonize the roots of plants and can promote plant growth. PGPR isolated and used as inoculum to seed or plants is mostly marketed as a growth stimulant because it facilitates registration and reduces costs, even though PGPR may also serve as biocontrol products.

  3. 2. Emissions of nitrous oxide associated with frost killed cover crops

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

    Author : Felicia Olofsson; [2022]
    Keywords : Nitrous oxide; cover crops; greenhouse gases; freeze-thaw cycles;

    Abstract : Agriculture is responsible for approximately 80% of anthropogenic emissions of the potent and long-lived greenhouse gas nitrous oxide (N2O). N2O emissions from agricultural soils are characterized by high temporal and spatial variability and often peak in short bursts related to events such as precipitation, fertilization and soil thawing.

  4. 3. Effects of microbial community coalescence in lake water at ice break-off

    University essay from

    Author : Christoffer Melhus; [2019]
    Keywords : Freshwater lakes; ice break-off; microbial community coalescence; dissolved organic matter; microbial enzymatic activity; primary production; photo degradation.;

    Abstract : The period of ice break-off in spring is a key event for many biogeochemical processes in lakes globallly. The biogeochemical processes occurring at ice break-off have the potential of influencing characteristics of lakes throughout spring and summer, including algal blooms and greenhouse gas emission.

  5. 4. Microbial composition of four kinds of tea with different degree of oxidation

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Song Tan; [2016]
    Keywords : probiotics; brewing; fermentation; microbial composition; Tea; oxidation degree; Bacillus coagulans; food technology; livsmedelsteknologi; Agriculture and Food Sciences;

    Abstract : In this study, four representative kinds of tea have been studied: Tie guan yin, Light oolong tea, Dark oolong and Pu-erh (oxidation degree from low to high). The microbial contents of four kinds of tea were analyzed under normal condition (without brewing) and after brewing. READ MORE

  6. 5. Bacterial communities associated with roots of narrow-leafed lupin (Lupinus angustifolius L.) : diversity in relation to soil origin and effects on plant growth

    University essay from SLU/Dept. of Plant Biology and Forest Genetics (until 131231)

    Author : Fang Chen; [2013]
    Keywords : lupin; Bradyrhizobium; symbiosis;

    Abstract : Bacteria play several important ecological functions in soil and in relation to plants. Legumes, such as the recently introduced grain legume narrow-leafed lupin (Lupinus angustifolius L.), develop N2-fixing root nodules in response to infection by soil bacteria generally called rhizobia but can also interact with other soil bacteria.
