What is recorded here?
Isolated the aerobic nitrogen-fixing microorganism named Azotobacter, adding a distinct route for investigating biological nitrogen acquisition outside a plant-root symbiosis.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The scope is Azotobacter isolation, not the first discovery of every form of biological nitrogen fixation. Earlier symbiotic and anaerobic work remains distinct. Institutional historical evidence supports this entry; this record does not include a direct check of the 1901 original article or later pure-culture measurements.
