Winoblog, Third post, group B7.

          This is the third post which we make about our “Winogradsky column”.
       By this time, the column has changed a lot. For example, microalgae have appeared in our column. To be more accurate, they have appeared in a water’s zone with oxygen.
           On the one hand, some gas bubbles have appeared in our column. That bubbles 
as a sign of metabolic activitiy. Cianobacteria produces oxygen using another componets of our “widnogradsky column”.

        On the other hand, stratification can be better appreciated. For example, under the water, there are a large area of ​​greenish gray. This is because microorganisms are growing up there, more specifically Beggiatoa is growing there.

         To sum up, we can se how the bio-system that we have created is becoming stable. Besides, we can appreciate differents strata that a couple of days before there werent there.

  1. Hi,
    Thanks for the post.

    Beggisatoa are sulfide oxidisers. They need oxygen and hydrogen sulfide to grow. They would appear as white filaments in your column. Do you see such filaments in yoru column?

    Next time try to take a closeup picture so we can see your pets better.
