Abstract:
This PhD thesis investigated soil formation during the reclamation of post-mining soils, focusing on bacteria that could enhance soil structure stabilization by producing exo- and lipopolysaccharides. An analysis of genes involved in their synthesis was performed in combination with measurements of bacterial extracellular polymeric substances (EPSs). EPSs were an important source of organic matter stabilizing soil structure in the long term and bacteria had the highest potential to produce polysaccharides at points of major disturbances.

In dieser Dissertation wurde die Entwicklung des Bodens bei der Rekultivierung von Tagebaulandschaften untersucht, wobei der Schwerpunkt auf Bakterien lag, die die Stabilisierung der Bodenstruktur durch die Produktion von Exo- und Lipopolysacchariden verbessern könnten. EPSs waren eine wichtige Quelle organischen Bodensubstanz, die die Bodenstruktur langfristig stabilisiert, und die Bakterien hatten das größte Potenzial, Polysaccharide in Zeiten größerer Störungen zu produzieren.
