Characteristics of Organic Acid Secretion Associated with the Interaction between Burkholderia multivorans WS-FJ9 and Poplar Root System

Figure 1

IAA secretion in strain WS-FJ9 and growth dynamic of bacterial cells. OD630 represents the proliferation of bacteria. At the initial stage of incubation (1–3 d), both the IAA content and bacterial biomass (denoted by OD630 value) in the fermentation broth of B. multivorans WS-FJ9 increased quickly and peaked at 3 d, with values of 23 mg·L–1 and 3.4, respectively.
