合成生物学在宠物食品中的应用前景展望OA

The continuous elevation of the social value of companion animals within family structures has propelled the rapid development of related industries.However,conventional raw material models relying on agricultural by-products or chemical synthesis face inherent limitations,such as high allergenic risks,large carbon footprints,and impurity residues.As a next-generation biomanufacturing technology,synthetic biol-ogy offers an innovative pathway to resolve these industry pain points through the engineered modification of microbial cell factories.This paper systematically reviews the application progress of synthetic biology in the pet food sector,with a primary focus on the biomanufacturing status of single-cell protein(SCP)and vari-ous functional nutritional ingredients(e.g.,lactoferrin,anti-allergen antibodies,collagen,and taurine).Con-currently,it provides an in-depth analysis of the multidimensional challenges encountered during the industrialization of this technology,including chassis cell modification,process scale-up,bio-safety,and ethical regulation.Finally,it outlines future developmental directions for the field,aiming to offer a theoretical reference for techno-logical innovation and industrial transformation within the pet industry.
