    Effects of infection history on dengue virus infection and pathogenicity
  5. 2045
    “…Therefore, strategies to minimize the flux to the shunt products and to maximize the supply of the amino-deoxyhexose moiety are implemented, which increase the acarbose titer by 1.2-fold to 7.4 g L(−1). This work provides insights into the biosynthesis of the C(7)-cyclitol moiety and highlights the importance of assessing shunt product accumulation when seeking to improve the titer of microbial pharmaceutical products.…”
