  2. 16. Mechanism of Action of the Plant Growth Promoting Bacterium Paenibacillus polymyxa

    Author : Salme Timmusk; Gerhart Wagner; Janet Jansson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Plant growth promotion; Induced resistance; Biocontrol; Deleterious rhizobacterium; Mikrobiologi; Microbiology; Mikrobiologi;

    Abstract : Paenibacillus polymyxa belongs to the group of plant growth promoting rhizobacteria (PGPR). Activities associated with P. polymyxa-treatment of plants in earlier experiments include, e.g. READ MORE

  4. 17. Virulence determinants of the insect pathogen Bacillus thuringiensis; : Molecular characterization of flagellins and the virulence protease immune inhibitor A

    Author : Ann Lövgren; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mikrobiologi; Microbiology;

    Abstract : Bacillus thuringiensis (Bt) is a motile, Gram positive, rod-shaped and spore-forminginsect pathogenic bacterium found on plants and in soil. The main insecticidal activityresides in a proteinacious crystal inclusion body (the S-endotoxin), but also the sporesare important for lethality. READ MORE

  5. 18. A song of ice and mud : Interactions of microbes with roots, fauna and carbon in warming permafrost-affected soils

    Author : Sylvain Monteux; Ellen Dorrepaal; Frida Keuper; James T. Weedon; Joshua Schimel; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microbial communities; permafrost; functional limitations; rhizosphere; SOM decomposition; soil fauna; climate change; carbon dioxide;

    Abstract : Permafrost-affected soils store a large quantity of soil organic matter (SOM) – ca. half of worldwide soil carbon – and currently undergo rapid and severe warming due to climate change. READ MORE

  6. 19. The influence of soil structure on microbial processes in microfluidic models

    Author : Carlos Arellano; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The way microbes behave in nature can vary widely depending on the spatial characteristics of the habitats they are located in. The spatial structure of the microbial environment can determine whether and to which extent processes such as organic matter degradation, and synergistic or antagonistic microbial processes occur.

  7. 20. Lignocellulose Degradation by Soil Micro-organisms

    Author : Ran Bi; Gunnar Henriksson; Jerry Ståhlberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Lignocellulosic biomass is a sustainable resource with abundant reserves. Compared to petroleum ‐ based products, the biomass ‐ derived polymers and chemicals give better environmental profiles. A lot of research interest is focused on understanding the lignocellulose structures. READ MORE
