Nitrogen Fixing Bacteria are the microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen, the inorganic compounds. Two kinds of nitrogen fixers are widely recognized i.e. Free-Living (non-symbiotic) bacteria and Mutualistic (symbiotic) bacteria. For Free-Living (non-symbiotic) bacteria like Azotobacter, Beijerinckia, Clostridium etc, a range of media such as Azotobacter Agar, Norris glucose Nitrogen free medium, Beijerinckia medium, Ashby’s Glucose agar and many more are developed and offered by HiMedia. Also for other root nodulating bacteria associated with leguminous plants and for Mutualistic (symbiotic) bacteria like Rhizobium , HiMedia provides media such as Yeast Mannitol Agar, Jensen Seedling Agar and many other media. |
