Growth of engineered E. coli strains with various vectors. The engineered E. coli were cultured in PYG medium with different expression hosts (a.) JM109 and (b.) JM109 (DE3). All strains were grown under anaerobic conditions at 37 °C for 60 h. The values and error bars are based on three replicate experiments
