Fig. 3From: Engineering of a genome-reduced strain Bacillus amyloliquefaciens for enhancing surfactin productionPhysiological characteristics assessment of strains. a Growth curves measured in LB medium; b growth curves measured in M9 medium; c the maximum specific growth rate (μmax) measured in LB medium; d the μmax measured in M9 medium; e transformation efficiency; f intracellular reducing power level (NADPH/NADP+ molar ratio); g The relative fluorescence intensities (GFP, green fluorescent protein; FI, fluorescence intensity). Values denote mean ± SD of triplicates (*P < 0.05, **P < 0.01)Back to article page
