Carbon and energy flow in the soil microbiome – functional groups, activity and interactions in trophic networks.

The interactions in the soil micro-food web between the microbiome and their grazers on soil carbon (C) turnover are not yet fully understood. While grazing reduces the number of microbes, it also increases their activity and mineralization rates, as well as their C investment in defense mechanisms. Bacterial predation on grazers (e.g., ‘pack-hunting’ myxobacteria) equally complicates a quantitative analysis of C flux. By combining a comprehensive analysis of a natural soil microbiome (PLFA- & DNA-SIP, metagenomic & amplicon sequencing) with a systemic analysis of a synthetic microbial & nematode community as well as nematode metabolic footprints (body mass & respiration) & different soil  conditions we hope to elucidate these mechanisms.

This project by Prof. Dr. Liliane Rueß & Miriam van Bommel is part of the SPP 2322 and in cooperation with Dr. Blagodatskaya (UFZ Halle), Prof. Dr. Ulrich (University of Greifswald), Prof. Dr. Prester (Leibnitz Institute - German Collection of Microorganisms and Cell Culture Braunschweig), Dr. Blagodatsky (University of Cologne), Prof. Dr. Kästner (UFZ Leipzig), Prof. Dr. Thiele-Brun (University of Trier), Prof. Dr. Kandeler (University of Hohenheim), and many others.
