Winogradsky column, Department of Biological Applications & Technology, Ioannina

Hello ,
our names are Christina Liagou and Zacharaki Panagiota and we are studying biology in Ioannina. This experiment conducted in order to observe the presence of microorganisms in our Winogradsky columns.The ingredients we used in each column were: 1 whole egg(source of CaCO3 and S), pieces of paper(source of C) and baking powder (source of S). These ingredients were mixed with mud that was taken from Voidomatis river (23th October 2015).We filled the bottles with 1/3 enriched sediment and the rest of them with extra mud and water from the river.We placed one column in the light and one other in the dark (both in room temperature) ,in order to distinguish differences between these conditions.Here we present our results!

1st day
In the left side is the dark column, and in the right side is the one placed in the light.

22/11: We notice some Fe production in both columns as we can observe orange and black colour in the dark and light column respectively.

15/1:This time we can observe that the sediment is getting even more darker in both cases and that the bottles are swelled so we can assume the activity of microorganisms.

  1. Well done girls! The left (dark) column has a green layer on the top of the sediment. Am I right? Any particular smell in your columns?
