Variations of Winogradsky Columns were designed, i.e. soil texture, light, salts, hard substrates, carbon and energy sources, Winogradsky Tanks to simulate wind and waves, Winogradksy Fuel Cells to monitor the redox potential of the biofilms, High Pressure Winogradsky to simulate water depth, etc. The influence of the Winogradsky’s environment on the biofilm patterns and vice versa were studied. The phenomenon of microbial succession was studied. The patterns were tracked by making Winogradsky Maps and mathematical data obtained by taking the Equivalent Weight of the pattern cutouts. Regression Equations were assessed to individual biofilm patterns. These equations were tested to predict the patterns. Finally a design for an all-environment simulation Winogradsky Column was laid. Innovative setups to simulate deep sea pressure were also done to see the consequent biofilm patterns.

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)
The objective of this project work is to design and build a Winogradsky column, a microcosm simulating natural aquatic environments. This column is intended to mimic the interaction of microorganisms and nutrients along a vertical gradient, establishing a miniature ecosystem that showcases the interplay of various microbial communities.
- Simulating Aquatic Microcosms
- Microbial Biofilm Formation
- Nutrient Gradients and Microbial Interactions
- Phototrophic and Chemotrophic Sulfur Oxidizers
- Microenvironmental Dynamics and Community Development
Zusammenfassung der Kapitel (Chapter Summaries)
