μ_max maximum specific growth rate (h⁻¹) on glucose, r_S specific glucose uptake rate (g/(g-DCW)/h), r_P specific α-amylase production rate (U/(g-DCW)/h) on glucose, Y_sα yield of α-amylase from glucose (U/g), r_E specific ethanol production rate (g/(g-DCW)/h), r_G specific glycerol production rate (g/(g-DCW)/h)

“*” represents the statistical significance of the difference between the parameters of YIGCS1 or YIGLO3 and those of YIGS16. *P < 0.05; **P < 0.01; ***P < 0.001. Measurements are reported as the average value ± standard deviation from independent triplicates
