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.

Frequently Asked Questions
What is a Winogradsky Column?
A Winogradsky Column is a microcosm designed to simulate natural aquatic environments, allowing the study of microbial communities along vertical nutrient and oxygen gradients.
How are biofilms studied in this project?
The study monitors biofilm patterns using Winogradsky Maps and mathematical data obtained from the equivalent weight of pattern cutouts to assess regression equations.
What are Winogradsky Fuel Cells?
These are specialized setups used to monitor the redox potential of the biofilms within the column, providing data on microbial metabolic activity.
Can Winogradsky Columns simulate deep-sea conditions?
Yes, the project utilized High Pressure Winogradsky setups to simulate water depth and observe the resulting microbial biofilm patterns.
What is the role of sulfur oxidizers in these columns?
Phototrophic and chemotrophic sulfur oxidizers are key microbial groups that develop in specific zones of the column based on the available light and nutrient gradients.
What is microbial succession in this context?
Microbial succession refers to the orderly change in the species composition of the microbial community over time as the environment within the column stabilizes.
