Abstract:

The large-scale application of bioenergy contributes to environmental protection and sustainable energy supply. At present,the recycling of carbon in the development of biofuel technology has emerged,but the recycling of nitrogen has not been given sufficient attention. Considering the wide variety and huge amount of protein-rich wastes,the conversion of the carbon backbone of amino acids in proteins into high value-added compounds such as biofuels,bulk chemicals and pharmaceutical intermediates is becoming a growing concern. From the perspective of the biological recycling of ammonia,this paper details an efficient,low-cost and sustainable production system of converting protein-rich biomass waste produced by photosynthesis into high-value compounds. In addition,the paper also summarizes the challenges and feasible strategies in further optimizing the biotransformation technology,which provides a reference for the low pollution and efficient production of high value-added compounds in the next step.

Key words: nitrogen balance, protein-derived biomass, biotransformation, high value-added compounds
