Invert sugar (C12H24O12) is a syrup of sugars dissolved in water. Calculate the return on biomass in C-mol X/C-mol S, knowing that at the end of a batch culture, 10.0 g/L of dry biomass was obtained, starting from an inoculum of 0.8 g/L, and 20.5 g/L of invert sugar (only FCE) was consumed. Set the equation for aerobic microbial growth without by-product formation.
