Ammonia producing bacteria/microbes

[octavian]

Hi,

I am pretty new to the subject of biology but I have a question that has been bothering me for some time: are there any form of bacteria or microbe that produces ammonia or solutions with a high ammonia content as a bi product? And if so, at what rate and under what conditions?

I would be thrilled if anyone could answer these questions.

Thanks.

Thanks mith,
one more thing though, is there any way of stopping the process before the ammonia is bonded to glutamate and becomes glutamine thus getting pure ammonia?
