^*Bio_max the maximum biomass; ^**r_glc the average glucose consumption rate; ^***Y_bio/glc biomass yield to glucose consumption versus the Bio_max. Statistics analysis was performed based on one-way ANOVA method and the data in the same column with the same letters (a–d) meant no significant difference (P ≤ 0.05)
