After a month we can appreciate several changes in the different sediments:
- At the top we can see how the green over the brown colour, that because there are more aerobic bacteria.
- In the middle we see that the zone is still black due to the nonsulfur photosynthetic bacterias, but now has appeared some pink zones due to purple non-S-bacteria.
- in the bottom it still black with some bubbles in there due to the fermentative processes of the microorganisms
You have several concepts mixed up... but nice colour of the purple sulfur bacteria
