Multicellular prokaryote

... the climate-resistant spores that may form when environmental conditions become harsh; and thick-walled heterocysts, which contain the enzyme nitrogenase, vital for nitrogen fixation. That just means they are not true multicellular prokaryotes.

Re:

http://en.wikipedia.org/wiki/Nitrogenase 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?

cellulolytic nitrogen fixing bacteria

... (i.e. fixing) it to NH3 (or its equivalent). You could measure the rate of N2 consumtion manometrically, I suppose. A proxy for measuring nitrogenase activity is to use acetylene reduction, but you’ll have to look up a method. I don’t know the techniques well enough. I’m not sure what ...
