Molecular Microbial Ecology

Ecology of anaerobic fungi (Neocallimastigomycota). Development of optimized tools for their detection, isolation and cultivation. Exploitation of their unique potential to degrade lignocellulosic material in order to improve anaerobic digestion processes. Investigating the microbial community associated with this peculiar microbial group.
Investigation of different DNA fractions and their role in biomonitoring- and microbial activity surveys.
