the mRNA level of B.s GalU is ~2.4 fold higher than that of E.coli, indicating the significant improvement of enzyme expression and activity. However, due to the lower expression of another key enzyme PGM for EPS production in BE strain, the final EPS yield is lower than that of EE strain but still comparable.
