University Of Thessaly

Group Number:13

Incubation:Light

Our samples were taken by Anauros (local beach of Volos, Greece) during our university field trip. In order to creat our Winogradsky column we followed the procedure bellow:
Step 1: We collected the sand sediment from Anauros beach
Step 2: We mixed the sand sediment with the enrichment materials (1 egg and pieces of newspaper)
Step 3: The sediment was added in a plastic bottle which was filled to the 2/3 of column 
Step 4: After that we added sea water to the rest of the column (1/3 of the bottle)
Step 5: The column was covered with transparent film
We put the column near a bright enough window, in relatively stable conditions.
Our column at the first day of the experimet
At the 10th day of the experiment  we can see the water bluring and changing color and becoming yellow. This is a result of the photosynthesis of  the phutoplankton.
At the 27th day we can see the color changed in to red. Due to FeO which can found it in sea sediment.
