is used for the million-ton-scale production of amino acids. Valorization of sidestreams from agri- and aqua-culture has focused on the production of biofuels and carboxylic acids. Nitrogen present in various amounts in sidestreams may be valuable for the production of amines, amino acids and other nitrogenous compounds. Metabolic engineering of for valorization of agri- and aqua-culture sidestreams addresses to bridge this gap. The product portfolio accessible fermentation primarily features amino acids and diamines for large-volume markets in addition to various specialty amines. On the one hand, this review covers metabolic engineering of to efficiently utilize components of various sidestreams. On the other hand, examples of the design and implementation of synthetic pathways not present in native metabolism to produce sought after nitrogenous compounds will be provided. Perspectives and challenges of this concept will be discussed.
用于百万吨级的氨基酸生产。农业和水产养殖副产物的价值化主要集中在生物燃料和羧酸的生产上。副产物中存在的各种数量的氮对于胺、氨基酸和其他含氮化合物的生产可能是有价值的。用于农业和水产养殖副产物价值化的代谢工程旨在弥补这一差距。通过发酵可获得的产品组合除了各种特种胺外,主要以面向大容量市场的氨基酸和二胺为特色。一方面,本综述涵盖了代谢工程,以有效利用各种副产物的成分。另一方面,将提供天然代谢中不存在的合成途径的设计和实施实例,以生产所需的含氮化合物。将讨论这一概念的前景和挑战。
