Beskrivning

Forskargruppen Mikrobiologisk ekologi arbetar med att identifiera de mikroorganismer som sköter omsättningen av kol och kväve i marken. Vi kartlägger vad som kännetecknar de här processerna på molekylär nivå och identifierar hur olika miljöfaktorer påverkar processerna. Huvudfokus är samverkan mellan svampar och växtrötter.

Forskning

Vår forskning syftar till att identifiera de mikroorganismer som sköter omsättningen av kol och kväve i jorden. Ett mål är att ta reda på vad som karakteriserar dessa processer och identifiera hur de är reglerade under olika miljömässiga scenarion. Vårt huvudfokus är att studera den symbiotiska samverkan mellan svamp och växtrötter. Vi undersöker också det parasitiska samspelet mellan svamp och jordlevande nematoder. Med hjälp av genomik, det vill säga studier av arvsmassa, undersöker vi evolutionen av symbiotiska svampar och parasitsvampar. Vi har utmärkta faciliteter för forskning på mikroorganismer i marken. Bland annat har vi växtkamrar, mikroskop och utrustning för kemiska separations- och analysmetoder, både högupplösande vätskekromatografi (HPLC) och gaskromatografi (GC). Hos oss finns Lund University DNA Sequencing Facility.

Mer om oss

Dimitrios Floudas Lab

We study the biochemical and molecular mechanisms that fungi use to cause organic matter transformation and decomposition focusing both on intact tissues such as wood, but also processed molecules such as soil organic matter. A fundamental part of our studies also includes a deeper understanding of the evolutionary processes that have shaped and keep shaping these mechanisms. Finally, we are also interested in harnessing metabolic processes of fungi for use in biomaterial applications. Our experimental methods include wet lab experiments, sequencing, spectroscopy and X-ray scattering.

Edith Hammer Lab

Soils store more carbon than the atmosphere and living biomass together, therefore are carbon compounds entering or leaving the soil C storage system of large importance for greenhouse effect mitigation. Soil organisms, and especially mycorrhizal fungi, channel large proportions of fresh carbon compounds entering the soil ecosystem, and we want to better understand their role in sequestering and stabilizing or decomposing soil organic matter.

Lettice C. Hicks Lab

We want to understand how microorganisms regulate the mineralization of carbon and nutrients from soil organic matter, both under steady-state conditions and during dynamic perturbations (for example drying-rewetting). To do so, we typically employ a range of isotope-based approaches which allow us to examine the microbial use and transformations of carbon and nitrogen in soil systems. We study soils from across the globe, but have been particularly interested in subarctic ecosystems which are undergoing rapid environmental change, leading to pronounced changes in microbial resource use and biogeochemistry.

Per Persson Lab

The main objective of my research is to provide fundamental understanding of chemical speciation, mechanisms and rate of reactions in the inherently heterogeneous aquatic and terrestrial environments. This is accomplished by a combination of techniques including Infrared and Raman spectroscopy, synchrotron-based X-ray absorption spectroscopy, X-ray photoelectron spectroscopy, Infrared microspectroscopy and imaging, and wet-chemical and theoretical methods.

Milda Pucetaite Lab

Studying single-cell physiology and responses to environmental triggers is crucial for increased understanding of how microbes in soil function and contribute to larger scale biogeochemical cycles. My research is thus aimed at disentangling the microscale chemistry of complex biotic and abiotic microbial interactions by taking use of advanced microspectroscopy methods at home laboratories and at synchrotron facilities.

Johannes Rousk Lab

We study the ecology of microorganisms in natural and engineered soil systems. We are interested in the factors that influence the spatial and temporal variability in microbial communities and how the microorganisms, in turn, control biogeochemistry in soil. We firmly believe that the secret to unlocking the ecology of microorganisms is to study how microbial growth rates respond to change, and we have a particular interest in comparing the roles of fungi and bacteria in their contribution to biogeochemical cycles.

Anders Tunlid Lab

My present research focuses on examining the molecular mechanisms underlying the decomposition of organic matter by ectomycorrhizal and saprotrophic fungi and how this activity affect the cycling of nutrients and carbon in forest soils. We are studying how the functional activities encoded in the genomes of fungi are linked to biogeochemical processes operating at different spatial scales – from nanoscale minerals to forest sites using methods from genomics, molecular geochemistry, physical chemistry and computational biology.

Håkan Wallander Lab

I work with ectomycorrhizal fungi that form symbiotic relationships with trees. They produce several hundreds of kilogram of mycelia per hectare every year in most forest ecosystems. This is important for nutrient uptake of the trees, but also for carbon sequestration and N retention in the soil. My main research interest is to understand how this flux of carbon below ground is regulated, and how important the composition of the ectomycorrhizal community is for carbon sequestration and nutrient uptake.
