This disclosure describes a recombinant microbial cells and methods of making and using such recombinant microbial cells. Generally, the recombinant cells may be modified to exhibit increased biosynthesis of a TCA derivative compared to a wild-type control. In some embodiments, the TCA derivative can include 1,4-butanediol. In various embodiments, the microbial cell is a fungal cell or a bacterial cell. In some embodiments, the increased biosynthesis of the TCA derivative can include an increase in xylose dehydrogenase activity, xylonolactonase activity, xylonate dehydratase activity, or 2-keto-3-deoxyaldonic acid dehydratase activity. |
