Research Topics
Project:

"Veränderungen in der Struktur und Funktion pelagischer Bakterien während und nach der Restauration des Tiefwarensees" - Molekularbiologische und physiologische Charakterisierung von limnischen Actinobakterien
(Changes in the structure and function of pelagic bacteria during and after the restoration of Lake Tiefwaren – Molecular and physiological characterisation of limnic Actinobacteria)



Research Interests:

- Analysis of the changes and variances of the Lake Tiefwaren over the period and after the restoration in relation to microbial diversity and the composition of the bacterial community

- Isolation and cultivation of dominant limnic Actinobacteria and previously not-yet-cultured Actinobacteria from different lakes of the Brandenburg-Mecklenburg Lake District

- Molecular, biological and physiological characterisation of the isolates

Research strategies:
Research on microbial ecology with traditional and classical microbiological techniques (isolation, cultivation, microscopy) and modern molecular methods (PCR, RT-PCR, DGGE, sequencing, FISH, CARD-FISH, phylogenetic analysis) for studies of the bacterial community. The cultivation combines "dilution series" and a "high-throughput screening".
Research activities take place in a combination of field work (different sampling sites) and laboratory experiments.
