Numerous studies of bacterial microbiomes in various natural habitats have shown that bacterial diversity still comprises a very large number of new and undescribed functional and taxonomic groups. In my research group, we mainly study the taxonomic and functional diversity of environmental and plant-associated bacteria, for example, associated with the roots of legumes or other plants, as well as marine diatoms and macroalgae, but also from extreme Antarctic soils where we find many coloured bacteria. This project will allow to support and refine our research in these areas, among other things through the purchase of necessary equipment for which no other funding has been obtained, support for open access publications and for the active participation in international meetings or workshops by doctoral students or other collaborators for whom no other support has been obtained.
