Pigmente phototropher Bakterien in Seesedimenten und ihre Bedeutung für die Seenforschung

Sediments of shallow lakes contain besides plankton pigments as well pigments of purple non-sulfur and purple sulfur bacteria. A thin-layer chromatographic method was developed for the separation of the most important pigments of purple bacteria beside plankton pigments. The new method was examined in three different lakes for a stratigraphic analysis of bacteria pigments beside plankton pigments and the results were discussed subsequently.
