Breaks down the nitrogen, turning it back into N2 gas.
Pseudomonas denitrificans
Denitrifying bacteria convert nitrates (NO3-) into nitrogen gas (N2) through a series of biochemical reactions. This process helps to remove excess nitrogen from the ecosystem, playing a crucial role in the nitrogen cycle.
Denitrifying bacteria produce nitrogen gas (N2) from nitrate (NO3-) or nitrite (NO2-). This process helps return nitrogen to the atmosphere in the form of N2, completing the nitrogen cycle.
nitrites
This is a misprint of 'denitrifying'. Denitrifying bacteria are commonly present in anaerobic environments, both in ocean sediments and freshwaters. They are responsible for the reduction of inorganic nitrogen compounds (nitrates NO3-) to gaseous nitrogen (NO, N2O and N2) and may be the source of all nitrogen gas in the atmosphere.
Three key types of bacteria involved in the nitrogen cycle are nitrogen-fixing bacteria, nitrifying bacteria, and denitrifying bacteria. Nitrogen-fixing bacteria, such as Rhizobium, convert atmospheric nitrogen into ammonia, making it accessible to plants. Nitrifying bacteria, like Nitrosomonas and Nitrobacter, further process ammonia into nitrites and then nitrates, which plants can absorb. Denitrifying bacteria, such as Pseudomonas, convert nitrates back into atmospheric nitrogen, completing the cycle.

The bacteria that can release nitrogen from nitrates and nitrites in the soil back to the atmosphere are called denitrifying bacteria.

The process of converting nitrate to nitrogen gas is called denitrification. This naturally occurs in soil, water, and sediment with the help of denitrifying bacteria. Denitrifying bacteria use nitrate as a source of oxygen and convert it into nitrogen gas, releasing it back into the atmosphere.
The nitrogen cycle relies on various microorganisms, particularly nitrogen-fixing bacteria, nitrifying bacteria, denitrifying bacteria, and ammonifying bacteria. Nitrogen-fixing bacteria, such as those in the genus Rhizobium, convert atmospheric nitrogen into ammonia, which can be utilized by plants. Nitrifying bacteria then convert ammonia into nitrites and nitrates, while denitrifying bacteria return nitrogen to the atmosphere by converting nitrates back into nitrogen gas. Together, these organisms play vital roles in recycling nitrogen in ecosystems.
Moves into the Atmospheric Nitrogen
If denitrifying bacteria were more active than decomposers, nitrogen-fixing bacteria, and nitrifying bacteria, there could be a significant reduction in soil nitrogen availability. This would lead to decreased nitrogen levels in the ecosystem, limiting plant growth and overall productivity. Additionally, the excess nitrogen gas released into the atmosphere could contribute to global warming and disrupt the nitrogen cycle, ultimately harming biodiversity and ecosystem stability.
