Team 11(Mylonas Ioannis - Mellos Giorgos)

Hello Winobloggers,
We are a two person team from university of Thessaly in Greece and our experiment was the Winogradsky column. We took samples (sediment and sea water) from Anavros region just little outside of Volos city.Also in our experiment we added an egg(as source of calcium and sulphur) and newpaper scraps (as source of cellulose). The place that we put our column was a close room with no light sources.

1st Day (18/3/15)
In the first day we put the materials of column in a plastic bottle.2/3 of this was sediment from Anavros mixture with newpaper scraps and the egg we mentioned above. And the rest 1/3 of it was filled with seawater. 

                                                                              Day 1                                                                              After 9 days (26/3/15)
We noticed that the 1/3 of sediment became slight darker from the rest.This is due the presence of FeS Which is produced by anaerobic microorganisms present in the column.

                                                                            Day 9
After 18 days (4/4/15)
We noticed that the 3/4 of sediment became darker from the rest.
                                                                           Day 18
After 1 month (18/4/15)
After a month that began the experiment we observed that the 4/5 of sediment has become black due to the presence of FeS in the sediment. While the remaining 1/5 has a gray color.
                                                                          1 month
After 1 month and 8 days (26/4/15)
We have noticed that all the column has become black due to the presence of Fes in the sediment.

                                                                    1 month and 8 days

  1. So you added egg yolk as Ca and S source. Where does the iron come from?
