FIGURE 3.

Online growth profiles (backscatter, growth rates, pH and DO) for all seven Ustilaginaceae species in medium 1 (A), medium 2 (B), and medium 3 (C) with an initial concentration of 30 g L^–1 glucose equivalent. Growth rates in medium 1 were high initially but then decreased fast. In medium 2, they were lower at the beginning but maintained over a longer time. Stationary phase was thus reached faster in medium 2. In medium 2, a stronger pH drift and higher oxygen consumption, resulting in low DO values, were generally observed.
