Chemicals produced by several Ustilaginaceae after 96 h (malate after 48 h) of cultivation in screening media buffered with 100 mM MES (M) or 33 g L⁻¹ CaCO₃ (C). (− = no production, + = < 1 g L⁻¹, ++ = 1–3 g L⁻¹, +++ = 3–6 g L⁻¹, ++++ = > 6 g L⁻¹, */- = no/low lipid production, * = low lipid production, ** = lipid production, *** = high lipid production).

^ano concentrations, relative ratio estimated from TLC.
^b Ustilago maydis 2162 was chosen as the best producer of itaconate, malate and succinate among all tested U. maydis strains.
