Abstract

Microbial protein is a promising alternative to animal and plant proteins. Aspergillus niger, a generally recognized as safe (GRAS) microorganism, is frequently used for heterologous protein production, although its expression efficiency is constrained by multiple factors, including gene transcription, metabolic flux distribution, protein folding, and secretion pathways. However, constructing universal Aspergillus niger chassis cells for efficient protein production remains challenging due to the diverse properties of different proteins. With advancements in synthetic biology, numerous molecular biology tools and metabolic engineering strategies have been employed to address these issues. This article summarizes and discusses the latest progress in enhancing heterologous protein production from five dimensions: expression systems, secretion pathways, metabolic flux, intelligent fermentation, and systematic optimization through multi-omics integration. Additionally, it prospects the efficient and sustainable production of heterologous proteins by Aspergillus niger.

黑曲霉高效异源蛋白表达的多维策略

微生物蛋白是一种很有前途的动物和植物蛋白替代品。黑曲霉（Aspergillus niger）是公认的安全微生物（GRAS），常用于异源蛋白的生产，但其表达效率受到多种因素的制约，包括基因转录、代谢通量分布、蛋白质折叠和分泌途径等。然而，由于不同蛋白质的不同性质，构建通用的黑曲霉底盘细胞以高效生产蛋白质仍然具有挑战性。随着合成生物学的进步，许多分子生物学工具和代谢工程策略被用来解决这些问题。本文从表达系统、分泌途径、代谢通量、智能发酵、多组学整合优化等5个方面综述了提高外源蛋白产量的最新进展。展望了黑曲霉高效、可持续地生产外源蛋白的前景。
