To overcome these limitations, bacterial glycoengineering has emerged as a simple, cost-effective, and scalable approach to produce designer glycoprotein therapeutics and vaccines in which the glycan structures are engineered to reduce heterogeneity and improve biological and biophysical attributes of the protein.
