Cadiz, 5B: winogradsky column 5B group

Hello, this is our first post in this blog. We are students from Cádiz University currently in the 1st year of Biotechnology.
For our Winogradsky column we have used: soil from the ground and the lagoon and sandy beach sediment taken from Rio San Pedro. It has been added material enrichment such as calcium sulfate, pieces of filter paper, motor oil and calcium nitrate. This was all mixed inside a bucket and placed in a bottle using a funnel, filling 3/4 of the Aquarius bottle with it then we added water from the tab to complete 4/5 of the Aquarius bottle. The column was created on tuesday , 3rd March in one the science laboratories of the faculty.
The bottle is placed on a balcony in Cádiz where the day temperatures are high and the nights temperatures are low, it also  only gets sun on one side, while the other side is facing the wall.
Our hypothesis is that in the top of the bottle grow aerobics microorganisms, and at the end grow microorganisms that do not need a lot of oxygen to live (anaerobics). The side of the bottle that receives sun, has green spots due to the appearence of photosynthetic microorganisms and in the side facing the wall there are black and big spots. The presence of paper make microorganisms that need carbon grow; with calcium sulfate, sulfate reducing microorganisms grow and with the calcium nitrate denitrifying microorganisms grow.

  1. So green already! Is it that green on both sides? If they are photosythetic organisms, does a lot of light reach the back side of the bottle?
