The River-WinoColumn

 The River-WinoColumn

Hello everyone,

         my name is Thomas Gkouletsos, an undergraduate Biology student in University of Ioannina in Greece. That's my Winogradsky Column (River-WinoColumn, RWC), which was constructed from a mixture of mud and water on 23/10/2015. I received the mud and the water from Voidomatis river. Exactly, the origin of the mud is from tree roots near the river bank. The RWC also contains substrates for enrichment. These are pieces of newspaper and leafs which were under the trees at the same place with the mud(soil). Furthermore, i placed an egg with its shell in the column,  the same time with the mud-water mixture, 1/2 powder from a baking powder sachet, and a banana without its peel. I added mixture until the 2/3 of the bottle to be filled up with water and the RWC was ready. I stored the RWC in my house (almost steady temerature 20 oC), next to the eastern window where the column was exposed to sunlight. 
         Today, after 86 days, the RWC has a bright red shade which is a result from a popuation of purple non-sulfur bacteria or/and purple sulfur bacteria. We can also observe a light green zone at the upper layer of the water which contains the biofilm. This zone probably owes its colour to Cyanobacteria.
         My goal is to observe different zones (with different shades) in the RWC over the time, as the biological processes in the column continue. 
        We will have more results here, stay focused!!!

  1. Come on be brave! comment about the smell...The water is red in both columns. The red shade you mention is on the sediment? What about this white zone on the top of the water?
