I'm curious . . . does anyone know the scientific name and common name of the bacteria in an aquaponics system? :?
Cheers :D

Nitrosomonas and nitrobacter. Just had to ask. :D

Which ones - nitrobacter and nitrosomonos are the ones often quoted, but the reality is that there are more than these performing the nitrification process. Will give you a start though if you are googling.

If you are interested in this the generic name for the above are autotrophs, the other significant bacteria type you will find in an AP system are the heterotrophs (in excess the ones we usually have problems with) :)
The other sub classification you should check, and this just relates to the requirement for O2, are aerobic bacteria and anaerobic bacteria.

Then when you've read the years and tomes of information available on nitrobacter and nitrosomonos ... and the nitrogen cycle....

Then read the latest research on nitrospira.... that suggests that the whole, almost universally accepted view.... is wrong...... :wink:

from the encyclopedia britannica (right click convert to pdf) if you stay too long they want you to pay monthly fees
l nitrification process ( in nitrifying bacterium )
...to nitrites (Nitrosomonas, Nitrosospira, Nitrosococcus, and Nitrosolobus) and bacteria that convert nitrites (toxic to plants) to nitrates
(Nitrobacter, Nitrospina, and Nitrococcus). In agriculture, irrigation with dilute solutions of ammonia results in an increase in soil nitrates through
the action of nitrifying bacteria
