Biochemical assessment of BC11-1. A single BC11-1 colony was inoculated in 10 mL of LB broth and cultured overnight at 28 °C on a rotary shaker. Then, 50 µL of suspension was placed into holes in the center of the various assay plates. The formation of a halo surrounding the colony revealed the ability of the BC11-1 to produce extracellular protease (A) and a siderophore (B). The assays also demonstrated phosphate solubilization activity (C). No evidence of extracellular amylase (D) or β-1 and 3-glucanase (E) activity was observed.
