The symbiont's role is thus strongly reminiscent of mitochondria, with the key difference that the endosymbiont derives energy from the respiration of nitrate, not oxygen. Now the researchers from ...

In addition to N 2 and NH 3, nitrogen exists in many different forms, including both inorganic (e.g., ammonia, nitrate) and organic (e.g., amino and nucleic acids) forms. Thus, nitrogen undergoes ...

My current projects investigate 1) nitrate respiration in anoxic or hypoxic environments using the bacteria Klebsiella oxytoca and 2) nectar inhabiting microbes from Aquilegia spp.
