Growth and glucose consumption assay of the R. sphaeroides mutant strains and WT

Strain	Time (h)	Glucose metabolism (g/L)	Bio_max^* (g DCW/L)	r_glc^** (g/L/h)	Y_b/glc^*** (g/g)
WT	84^b	6.21 ± 0.21^a	2.23 ± 0.07^b (72 h)	0.074 ± 0.003^b	0.36 ± 0.02^b
Δglk	96^a	2.47 ± 0.04^b	0.82 ± 0.01^c (96 h)	0.026 ± 0.001^c	0.33 ± 0.01^c
ΔfruAΔfruB	72^c	6.19 ± 0.16^a	3.22 ± 0.04^a (60 h)	0.086 ± 0.002^a	0.52 ± 0.03^a

^*Bio_max the maximum biomass; ^**r_glc the average glucose consumption rate; ^***Y_b/glc biomass yield to glucose consumption vs. 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–c) meant no significant difference (P ≤ 0.05)
