We have bad news for you, today is our last post.... :(

Our column has been changing during these days since the last time we saw them and we posted it.

The changes produced are:

Column in contact with light:

We can appreciate a change of color from brown to orange. That color manifestate the appearance of the bacteria Rhodospirillum which is photosynthetic

On the other side, we can see some green spots which we think they are algae. Also in this part we can appreciate some black spots at the bottom, which means that are anaerobic organisms.

Column without light contact:

The only change that we can see, is that the difference bettween anaerobic and aerobic is more defined.
