Sustainable Biological Ammonia Production towards a Carbon-Free Society

A sustainable society was proposed more than 50 years ago. However, it is yet to be realised. For example, the production of ammonia, an important chemical widely used in agriculture, steel, chemical, textile, and pharmaceutical industries, still depends on fossil fuels. Recently, biological approaches achieve ammonia have been gaining attention. Moreover, unlike methods, a lesser environmental impact because can produced under mild conditions normal temperature pressure. Therefore, previous studies, nitrogen fixation by nitrogenase, including enzymatic using food waste, has attempted. Additionally, crops nitrogen-fixing bacteria implemented industry as one most promising achieving economy. Thus, this review, we described studies showed prospects for realising society.
