The following points highlight the top two types of Biological Nitrogen-Fixing Agents. The types are: 1. Symbiotic Nitrogen Fixers 2. Non-Symbiotic Nitrogen Fixers. Biological Nitrogen-Fixing Agent: Type # 1. Symbiotic Nitrogen Fixers: A. Legumes and Nodule Bacteria: Leguminous crops, mainly peas, beans, clovers, soybeans etc., can fix about 14 x 106 metric tons of nitrogen on earth per year through [...]
The following points highlight five reactions on direct assimilation of ammonia into organic compounds. The reactions are: 1. Reductive Amination 2. Transamination 3. Formation of Amides 4. Direct Amination of Fumarate 5. Synthesis of Carbamoyl Phosphate. Reaction # 1. Reductive Amination: The general principle of this process is the formation of amino acid from a keto acid reacting with ammonia [...]
