Zostera marina and epibionts : the dynamics of chemical defenses

In the dissertation, we described the existence of the chemical antifouling defense of Zostera marina. In general, the surface compounds on Z. marina are able to repel bacterial foulers in a non-toxic way. Three compounds were separated from the surface of Z. marina and rosmarinic acid was the most abundant...

A molecular survey of Ulva sensu lato on German Baltic- and North Sea coasts:...

In this doctoral project, I investigated the recent inventory, distribution and phylogenetic relationships of Ulva sensu lato in northern Germany, including sampling sites at the Baltic Sea, Wadden Sea and on Helgoland. Furthermore, I compared the recent results with historic findings. Therfore, this...

Naturstoffe algenassoziierter Bakterien & Naturstoffe der Gattung Pseudomonas...

Die Ergebnisse dieser Arbeit zeigen, dass eine Assoziation von Bacillus-, Pseudomonas- und Streptomyces-Arten mit der Braunalge Saccharina latissima in der Ostsee besteht. Im speziellen kann für den Pseudomonas-Stamm LD120 auf Grund des Sekundärmetabolitprofils sowie der stoffwechselphysiologischen Eigenschaften...

Community of soft coral Alcyonium digitatum associated bacteria and their...

Discovery of novel natural products from soft corals were reported with many achievement so far. Soft coral associated bacteria have gained interest for several reasons such as for marine environmental protection and bio-mining of natural products from microorganism as compared to the animals. This work...

Is fouling a determinant of invasion success? - A comparison of the...

The number of introduced species, also called non-native or invasive species, has substantially increased in both terrestrial and aquatic ecosystems worldwide in past years. One possible reason for invasion success, i.e. the permanent establishment and spread after introduction, could be a high resistance...
