Dear Tobias,

I explore about lysinibacillus lusiformis and found oit that it capable of ammonia oxidation. I am sending you the pathway link please refer. (http://www.genome.jp/kegg-bin/show_pathway?lsp00910)

Hi Ishan, I can remember that on the ISME in Kopenhaven, there was a poster of a group they provided the idea that bacillus is able to nitrify. It is right that heterotrophic organisms can nitrify but they gain no energy from this process. Normally the nitrifying gene normally used as a gene marker are the amoA for Ammonium oxidation and NXR for nitrite ixidation. In your think the gene named "PmoA" and "NorAB" that are not the key enzymes for nitrification. Or I missunderstood your link.

My PhD was about Ammonia oxidizers in permafrost soils.

Tina,

Thanks for you beneficial response. I need to degrade ammonia in gaseous form. I have isolated some bacteria in which lysinibacillus lusiformis is one of it. My concern is more on to oxidize ammonia and in process the bacteria should replicate its growth by taking nitrogen source from ammonia.

Please put a light on the above point.
