Winogradsky Experiment - TEAM A

University of Ioannina
Team A (Gregoris Notarides & Kostas Karanicolas)

Hello everyone.

In our experiment we will observe possible differences at the growth of microorganisms in two Winogradsky columns, presence of light at the first column and completely dark environment for the second one.

Sampling of mud and water done on 21th of October 2016 at 13:00 o'clock, in Vrellis Lake of Ioannina. For the creation of our Winogradsky's columns we used two plastic bottles of 1,5 L capacitive, where we put mud mixed with raw eggs and sheets of newspaper in small pieces.

We made three layers in our columns. First layer was the mud with the enrichment materials and second layer, simple mud without them until the 2/3 of the bottles. Third and final layer was water direct from the lake, without any subtraction of phytoplankton.

Our columns were placed in the laboratory, one in front of a window and the other inside a closet where the sun can't see it.

We expect the development of microorganisms in the column that is in front of the window will be faster and will give higher numbers, as we suppose that several species of microorganisms won't grow up in the second column where they will cannot perform photosynthesis without the presence of sun's light.

  1. You could probably compare your results to those of team 7. Good luck!
