Three weeks later,
Hello again, in this new post we will report on the changes in our column. We were surprised to see so much biodiversity.
-At the top where sunlight and air play an important roll, we can see aerobic bacteria like Cyanobacteria for example, we realize filamentous structures (fungi) and micro algae. A little bellow it is seen a big bubble and many mechanic chamber made by the enormous amount of organic matter added (CaCO3 breakdown produces CO2 and white substance which it is seen that is CaO).
-In the middle we realize three well differentiated parts. All are anaerobic zones.
- -First is dark and it will have nonsulfur photosynthetic bacteria like Rhodomicrobium.
- -Second zone is more reddish due the presence of Purple-S-bacteria.
- -The last is more greenish due the presence of Green-S-bacteria like Clorobacterium.
-Finally at the bottom it will have anaerobic sediments. It is the darkest. It is seen a Mud mixed and carbonate salts, cellulose or other organics. In this part fermentative processes are carried out by bacteria such as Clostridium and Desulfuvibrio (Chemolithoautotrophs).
To restore balance, we shake the column to remove the bubbles. In the next post we will report on new changes. See you latter! :)
I am just wondering where you appreciate all these different zones. Can you show them on your columns?
ReplyDelete"aerobic bacteria like Cyanobacteria for example"
Cyabobacteria are photosynthetic microorganisms or green-blue colour.
"filamentous structures (fungi) "
If you see any filament these are probably algae. Fungi are not visible to the eye in the marine environment same as in soils and actually their importance has only recently been highlighted.
"white substance which it is seen that is CaO" The white stuff you see is not CaO. Any ideas?
"nonsulfur photosynthetic bacteria like Rhodomicrobium... zone is more reddish due the presence of Purple-S-bacteria... more greenish due the presence of Green-S-bacteria like Clorobacterium." I cannot appreciate the green colour. In any case the bacterium Clorobacterium does not exist. What were you referring to?
Definitely an interesting columna and observations.
