Winoblog, Second post, group B7.

            In this second post, we can appreciate a change in the colour of our “Winogradsky column”. The methane wall cavity has been deleted, because organic substance’s excess was consumed. Besides, is possible to see muddy water. 

            In addition, a rosy colour appears, because a microorganism like Chromatium uses CO2 and H2S to create organic molecules. On top of rosy stratum, we can see other stratum more light where we find Rhodomicrobium. Rhodomicrobium uses CO2 and organic acids to produce organic molecules.

             Finally, at the beginning of Winogradsky column, there is a space that has oxygen. This oxygen is utilized for filamentous microorganism like Beggiatoa, it produces sulfuric acid and organic molecules. Besides that, on wáter, photosynthetic mirobes make their work.

  1. Did you actually see white filaments indicative of Beggiatoa?
    Purple sulfur bacteria appeared after how many days? from which day are these pictures from?
