Beobachtung von Diatomeen

Epiphytic diatoms

A raw culture was prepared with diatoms of the genus Nitzschia and Pinnularia. Small epiphytic diatoms (Amphora pediculus or Cocconeis pediculus) came into the culture together with Nitzschia and proliferated strongly. They grew attached to the substrate and the diatoms of the genus Nitzschia but not on Pinnularia. The latter can be easily transferred from the raw culture to a new culture. The following video (120x time lapse) shows the culture at different magnification levels.
