\nAzotobacter and Clostridium are genera of free-living bacteria known for their ability to fix atmospheric nitrogen. Nitrogen fixation is the process by which gaseous molecular nitrogen (N\u2082, which is abundant in the atmosphere but unusable by most organisms) is converted into ammonia (NH\u2083), which can then be incorporated into organic molecules usable by plants and other organisms. Azotobacter is aerobic, while Clostridium is anaerobic.
\n<\/section>\n
\n– Azotobacter and Clostridium are free-living nitrogen-fixing bacteria.
\n– Nitrogen fixation is the conversion of N\u2082 gas into ammonia (NH\u2083).
\n– This process is essential for making nitrogen available in ecosystems.
\n– Ammonia can be further converted into other nitrogen compounds like nitrates by other bacteria (nitrification).
\n<\/section>\n
\nNitrogen fixation is a crucial part of the nitrogen cycle. Besides free-living bacteria like Azotobacter and Clostridium, symbiotic bacteria (like Rhizobium in legume root nodules) are also major nitrogen fixers. Denitrification, the conversion of nitrates back to N\u2082, is carried out by a different group of bacteria.
