Lars-Erik Petersen, PhD-candidate
Chemical ecology and natural product chemistry
- Links between chemistry and microbiology of marine macro- and microorganisms
- Effects of environmental variability (e.g. increasing sea surface temperature and decreasing seawater pH) on the production of secondary metabolites from holobionts
I am participating in the interdisciplinary PhD Research Training Group “EcoMol” (“The Ecology of Molecules”) which is supported by the Ministry of Science and Culture of Lower Saxony. Within the EcoMol project, I will investigate the role of bacteria and holobiont signaling molecules in coral settlement processes. The aim of my project is to achieve a deeper understanding concerning the importance of Dissolved Organic Matter (DOM), as it serves as signaling compounds among organisms belonging to different kingdoms (e.g. plantae, animalia, bacteria).
Microbiology: isolation and cultivation of bacteria and fungi from marine samples
Molecular Biology: DNA extraction, PCR, sequence analysis
