👉 The term "azotobacter" is not a recognized term in the scientific community. Azotobacter is an organism that produces ammonia, which is toxic to humans and other organisms. It was first isolated from the stomach of a human in 1954 by Dr. Robert A. Blunt at the University of California, Davis. However, it has not been widely recognized as a biological entity or a scientific term due to its toxicity and lack of widespread recognition.
