Dr. Julius Degenhardt

Research interests

I investigate the role of microbial communities in marine sediments in the degradation recalcitrant dissolved organic matter (DOM) and anaerobic processes like metal- and sulfate reduction. 

Therefore I study environments like coastal aquifers or deep mud flat sediments.
