Fig 3. Effects of Pseudomonas fluorescens strain 3JW1 on AFB₁ production in peanut kernels (μg/kg).

Peanut kernels were surfaced-disinfected with 0.1% sodium hypochlorite, rinsed with sterile distilled water 3 times, air-dried in a petri dish. Tewenty peanut kernels were used in each assay. One ml of biocontrol strain 3JW1 at 1.0×10⁷ CFU/ml was added into petri dish, 4h later, 1 ml A. flavus at 1×10⁷ CFU/ml was added into petri dish. All petri dishes were placed in an artificial weather chamber (humidity 85%, 28°C). The amount of AFB₁ was determined by IAC-HPLC 7 days later. Each treatment was replicated three times and this study was repeated four times.
