In the experimental procedure, SmF was carried out at 25 and 37 °C while keeping the
other growth conditions (200 rpm, pH 6, and 25 g/L of TSC) constant. After 72 h of SmF, the
fungal biomass exhibited two distinct morphologies. The experiment carried out at 25 °C
produced solid pellets with a reduced diameter (1 mm, Fig. 4a) compared with pellets obtained
at 30 °C (3–5 mm, Figs. 2b and 3b). The other experiment designed for 37 °C resulted in
suspended mycelium (Fig. 4b). The important outcome of this experiment was the marked
increase in the production level of FA. The FA concentration reached 23.66±2.1 g/L in 72 h of
SmF. This is almost 10 g/L more as compared with the maximum concentration (14.16±1.9 g/L) of FA obtained at 30 °C, 200 rpm, and pH 6. The FA concentration for 37 °C was very low
(2.88±1.33 g/L).
