Hello fellow winobloggers! We are Kalliopi Tzani & Olga Mavridi, under graduate students in the field of Biological Applications & Technology in the University of Ioannina. In terms of a class/ curriculum concerning aquatic microorganisms, we were assigned to make a Winogradsky column. For this purpose, we placed lake soil and lake water, from the Vrelis’s lake, into three bottles in a ratio 2:1. Each bottle contained lake soil and newspaper as source of cellulose. The bottles, however, contained different sources of Sulfur. In the first one, we added an egg, with its pod. The second one contained garlic & the third one contained both of these sources of sulfur (egg & garlic). Our bottles were closed, as to not exchange gasses like oxygen, with the environment, and they were placed in a sunny room. We observed them in a weekly base and we stated the following hypothesis: if there will be a differentiation between the 3 bottles concerning microorganisms’ development.
