Well, maybe not everything, but a lot.  In particular, many people on this forum assert that the bacteria die shortly after losing a food source.  This apparently is wrong:

That's very interesting, thanks for posting it. As the author made clear, most responsible aquarists everywhere, not just on this forum, have stated the facts as we knew them. Smiley There's always been a lot of gaps and plenty of argument on the theories. I'm glad to see someone is still working on it, although, given that the new indications are incomplete I wouldn't necessarily change my maintenance habits... not just yet.

"Even this is not the case, with studies suggesting that nitrifying bacteria can switch their metabolisms, resulting in resting cells, or even by switching from nitrifying to denitrifying behaviour".


That is a very good article. However, it is not really new information. It has just been presented in a updated mode. I read about these and similar Nitrosomonas properties back in the early 90s. It is very well simplified from the more heavier reading of the linked study papers. happy  Bottom line...still a really great read.

It was a fun read...thanks for posting mchambers.

But what's even more interesting is the linked article in the comments field. There may be a new ammonia oxidizing player in our aquaria.

Looks lke I'll be googling 'Thermarchaea' and 'Josh D. Neufeld' quite a bit in the future.  happy

Thanks for pointing that out, Tom.  Here's the link.  Now I'm even more confused, however.

Thanks for the link Matt!  A study based on bio filtration in aquariums... now we're getting somewhere!
