Can bacteria nitrify ammonia if it is bonded to a base?

In summary, the conversation discusses whether nitrifying bacteria can still convert ammonia to nitrites and nitrates if it is bonded to chlorine in the form of NH4Cl. The speaker also mentions their plans for an aquaponics set-up and their desire to balance the amount of ammonia in the water without reaching toxic levels, potentially by using a different anion than chloride. They also mention the solubility of NH4+ with different anions and the use of siderophores to make certain ions more bioavailable for bacteria.

If an ammonium ion is bonded to let's say chlorine for simplicity sake, and NH4Cl is created, can nitrifying bacteria come in and still create nitrites and nitrates from the ammonia if it is bonded to the chlorine? I am asking this because I am planning to make a schematic for an aquaponics set-up and I want to balance the amount of ammonia in the water as possible, in my case with a base not chlorine, in order to be able to add more ammonia at once to the system without the water reaching toxic levels. Thank You!

Can you rephrase your question? It appears you wish to use a different anion than chloride, but the way you've written it, it also appears you think that ammonium salts are undissociated in aqueous solution.

Thats true. So the dissociated salts will have no effect since the ammonia is In ion form. Thank you

NH4+ is very soluble in combination with most common anions, but not all ions bacteria want to use are nicely soluble. For example, Fe3+ often sediments and concentrations naturally become very low. So siderophores are released to chelate Fe3+ ions away from their salts to make them bioavailable.

1. Can bacteria nitrify ammonia if it is bonded to a base?

Yes, bacteria can still nitrify ammonia if it is bonded to a base. Nitrification is the process by which bacteria convert ammonia into nitrites and then into nitrates, which can be used by plants as a source of nitrogen. This process is essential for the nitrogen cycle and can occur whether ammonia is bonded to a base or not.

2. How do bacteria nitrify ammonia bonded to a base?

Bacteria use a process called oxidation to nitrify ammonia bonded to a base. This involves breaking down the ammonia molecule and combining it with oxygen to produce nitrites and then nitrates. Different bacteria species use different enzymes to carry out this process.

3. Are there specific bacteria that are responsible for nitrifying ammonia bonded to a base?

Yes, there are specific bacteria that are known to nitrify ammonia bonded to a base. These include Nitrosomonas, Nitrosospira, and Nitrosococcus. These bacteria are commonly found in soil and water and play a crucial role in the nitrogen cycle.

4. Can other organisms besides bacteria nitrify ammonia bonded to a base?

While bacteria are the primary organisms responsible for nitrifying ammonia bonded to a base, other microorganisms such as archaea and fungi can also play a role in this process. However, bacteria are the most efficient and abundant nitrifiers in most environments.

5. Is nitrification affected by the presence of ammonia bonded to a base?

Nitrification can be affected by the presence of ammonia bonded to a base. The process may be slowed down if there is a high concentration of ammonia bonded to a base, as it may compete with free ammonia for the bacteria's attention. However, bacteria can still nitrify ammonia bonded to a base, and the process will continue as long as there is enough oxygen and the right bacteria present.
