Caroline Scholze

During her studies, Caroline Scholze researched the temperature dependence of the microorganisms that drive the degradation of organic carbon in marine sediments. The most important degraders of organic carbon in anoxic marine sediments are sulfate reducing microorganisms. Caroline Scholze studied how sulfate reduction in marine sediments can be high despite low temperature conditions in Arctic sediment, which can be ascribed to the adaptation towards low temperature of sulfate reducing microorganisms. In Aarhus bay, it was studied whether the adaptation towards temperature would change with increasing sediment depth, indicative of ongoing selection with depth.

The new research findings contribute to the understanding of how microorganisms adapt to temperature and counteract its negative effects on microbial activity.

The PhD degree was completed at the Center for Geomicrobiology, Bioscience, Science and Technology, Aarhus University.

This résumé was prepared by the PhD student.
