R. oryzae 1526, but FA production was lowered (Fig. 1). The inverse relation between TSC
versus FA concentration was due to the broth rheology. The broth viscosity was highly prone
to TSC and fungal morphology [16]. The TSC concentration supporting the pellet formation
has provided the double benefits of lower viscosity and more production of FA, while
formation of suspended mycelium increased the viscosity. TSC concentration of 25 g/L was
considered to be the optimum one as fungal pellets and higher production FA were obtained
