- Abstract: Synthetic biology and metabolic engineering have been widely used to construct microbial cell factories for efficient production of bio-based chemicals, which mainly focus on the modification and regulation of metabolic pathways. The characteristics of microorganisms themselves, e.g. morphology, have rarely been taken into consideration in the biotechnological production processes. Morphology engineering aims to control cell shapes and cell division patterns by manipulating the genes related to cell morphology, providing a new strategy for developing efficient microbial cell factories. This review summarized the proteins related to cell morphology, followed by illustrating a few examples of using morphology engineering strategies for improving production of bio-based chemicals. This includes increasing intracellular product accumulation by regulating cell size, enhancing extracellular secretion of target products by improving cell permeability, reducing production cost by achieving high cell density, and improving product performance by controlling the degree of product hydrolysis. Finally, challenges and perspectives for the development of morphology engineering were discussed.
