目前,已经开发了合成生物学方法来构建能够有效合成高附加值产品的微生物细胞工厂。大多数研究都集中在构建新的生物合成途径及其调控过程。形态工程是近年来提出的一种构建高效微生物细胞工厂的新策略,其目的是通过操纵与细胞形态相关的基因来控制细胞的形状和分裂模式。形态工程策略已被开发用于提高细菌生长速率、扩大细胞体积和简化下游分离。本文综述了细胞形态学相关蛋白及其功能、形态学工程操作工具和策略的研究进展,以及形态学工程在提高胞内产物聚羟基脂肪酸酯和胞外产物产量中的实际应用。最后指出了形态学工程应用的局限性和未来的发展方向。
Currently, synthetic biology approaches have been developed for constructing microbial cell factories capable of efficient synthesis of high value-added products. Most studies have focused on the construction of novel biosynthetic pathways and their regulatory processes. Morphology engineering has recently been proposed as a novel strategy for constructing efficient microbial cell factories, which aims at controlling cell shape and cell division pattern by manipulating the cell morphology-related genes. Morphology engineering strategies have been exploited for improving bacterial growth rate, enlarging cell volume and simplifying downstream separation. This mini-review summarizes cell morphology-related proteins and their function, current advances in manipulation tools and strategies of morphology engineering, and practical applications of morphology engineering for enhanced production of intracellular product polyhydroxyalkanoate and extracellular products. Furthermore, current limitations and the future development direction using morphology engineering are proposed.
