EXPRESSION SYSTEM FOR PRODUCT MANUFACTURING

Abstract: the present disclosure provides engineered bacterial cells having one or more genetic modifications that result in increased production of expression products, such as increased production of plasmids with reduced occurrence of plasmid concatemers or multimers. also disclosed herein are expression systems for product manufacturing in media having reduced antibiotic concentration, as well as methods of making cells for use in the expression systems. the cells and expression systems increase the growth rate and production yields of biomolecules produced within the host bacterial host cells without the use of antibiotics, and can produce the product with little to no endotoxins present.
