University of Thessaly
Group: 17 (Bobotis & Boziki)
Days: 1 - 72
Incubation: Light


Our experiment was to observe the possible alterations in the Winogradsky column, which occure due to the different types of microorganismic activity. The experiment began in Volos, Anavros. We used a plastic bottle (1,5L), seawater, pieces of paper, some sediment taken from the beach and an egg. After mixing the sediment with the paper and the egg, we filled the rest of the bottle with seawater and placed it in a spot that provided it with light during the entire day and stable temperature.

On the 1st day it looked like this:

 


After a week it started getting blurry:

 


After only two weeks the sediment was already very dark coloured:








 

 One month since the start of the experiment, it smelled badly and developted some kind of mold:




Then after only a few days it got a lot darker and very fast:




And it continued deteriorating since:




Until the end of the experiment that it did not smell at all and looked like this:
