University of Thessaly, Group number:31 , Day number: 9 Incubation: Light
Our names are Panagiotis Papastathopoulos and Vlachakis Sotirios and we are undergraduate students Department of Ichthyology and Aquatic Environment, University of Thessaly, Volos, Greece.
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). These ingredients were mixed with sand that was taken from Anauros beach in Volos(21th March 2016).We filled the bottle with 2/3 sand and the rest with water from the sea. The bottle was put in conditions with light intensity and temperatures of 15-20°C.

Today ,9 days after the column was made some change.The mud seems to took darker colour, the water took yellow-beige and we can observe a white line between the sand and water.
Descriptions are ok, but any educated guess on what has happened in the column during the first 9 days?
