Escherichia coli is commonly used as a model bacteria in defining microbial cell factories and studying regulatory mechanisms. The outer membrane associated molecules such as phospholipids and lipopolysaccharides play important roles in cellular morphology and stress adaptation, but can also lead to contamination and nutrient consumption. Understanding the biosynthesis and functions of these molecules is crucial for improving microbial producers.
Escherichia coli is generally used as model bacteria to define microbial cell factories for many products and to investigate regulation mechanisms. E. coli exhibits phospholipids, lipopolysaccharides, colanic acid, flagella and type I fimbriae on the outer membrane which is a self-protective barrier and closely related to cellular morphology, growth, phenotypes and stress adaptation. However, these outer membrane associated molecules could also lead to potential contamination and insecurity for fermentation products and consume lots of nutrients and energy sources. Therefore, understanding critical insights of these membrane associated molecules is necessary for building better microbial producers. Here the biosynthesis, function, influences, and current membrane engineering applications of these outer membrane associated molecules were reviewed from the perspective of synthetic biology, and the potential and effective engineering strategies on the outer membrane to improve fermentation features for microbial cell factories were suggested.
