The experiment started on 21/3/16 at Anauros beach. The protocol that we followed is shown below:
1) We took the sediment from the bottom of the sea and mixed it with a few pieces of newspaper and a broken egg with its shell.
2) We filled the 2/3 of a plastic bottle with the mixed sediment and filled the rest with sea water.
3) We covered the column with a trasnparent film and placed it behind a sunny window.
The first day the sediment had a light brown color and the water was light yellow (because of the broken egg).
As the days passed, the color of the sediment began to darken until it became black. On the contrary the water became lighter and after a period of 20 days it turned into purple red as a result of the photosynthetic microorganisms. At the same time the scent of the sample went from bad to worse.

Nice color, nice column! What type of photo synthetic bacteria are they?
ReplyDeleteWait and keep looking for green color appearing below the purple one.
I think that sea water columns are doing better regarding purple bacteria than freshwater ones ... or not?
