abstract = {Ustilago maydis, a member of the Ustilaginaceae family, is
a promising host for the production of several metabolites
including itaconic acid. This dicarboxylate has great
potential as a bio-based building block in the polymer
industry, and is of special interest for pharmaceutical
applications. Several itaconate overproducing Ustilago
strains have been generated by metabolic and morphology
engineering. This yielded stabilized unicellular morphology
through fuz7 deletion, reduction of by-product formation
through deletion of genes responsible for itaconate
oxidation and (glyco)lipid production, and the
overexpression of the regulator of the itaconate cluster
ria1 and the mitochondrial tricarboxylate transporter
encoded by mttA from Aspergillusterreus. In this study,
itaconate production was further optimized by consolidating
these different optimizations into one strain. The combined
modifications resulted in itaconic acid production at
theoretical maximal yield, which was achieved under
biotechnologically relevant fed-batch fermentations with
continuous feed.},
