Fig. 7From: Whole transcriptomic analysis of the plant-beneficial rhizobacterium Bacillus amyloliquefaciens SQR9 during enhanced biofilm formation regulated by maize root exudatesEffects of specific components in maize root exudates on biofilm formation and growth of SQR9. a Effects of different concentrations of glucose on the biomass of biofilm formed by SQR9 after incubation for 24 h. b Effects of glucose (Glucose 1, 500 μM; Glucose 2, 1 mM), citric acid (50 μM) and fumaric acid (50 μM) on the growth of SQR9 under aeration at 8 h post-inoculation. Columns with different letters are statistically different according to the Duncan’s multiple range tests (P < 0.05)Back to article page
