Figure Lengend Snippet: Figure 2. Anguibactin production from Vibrio harveyi. (A) Bioassay to test anguibactin production. CC9-16ΔfvtAΔfetA was used as an anguibactin indicator strain. EDDA (40 lmol/L) and Cm (10 lg/mL) were added into AB media with the indicator strain. Five microliters of overnight culture of V. harveyi HY01 (pMMB208), V. harveyi BAA-1116 (pMMB208), and Vibrio anguillarum 96F (pMMB208) grown in AB broth with Cm was spotted on the plates, and incubated at 25°C. Presence of growth halos around spots was checked every 24 h. Vibrio anguillarum 96F (pMMB208) is a vanchrobactin producer and was used as a negative control. (B) Structure of anguibactin from V. anguillarum 775 (pJM1) (Jalal et al. 1989). (C) Confirmation of anguibactin biosynthesis in the V. harveyi HY01 strain. Positive mode electrospray ionization-mass spectra of the purified siderophores without (above) and with (below) 30% collision energy.

Figure Lengend Snippet: Figure 3. Characterization of the angR gene in Vibrio harveyi HY01. (A) The angR gene is essential for the anguibactin production in V. harveyi HY01. Vibrio anguillarum CC9-16ΔfvtAΔfetA was used as an anguibactin indicator strain. EDDA (40 lmol/L) and Cm (10 lg/mL) were added into AB media with the indicator strain. Five microliters of an overnight culture of V. harveyi HY01 (pMMB208), V. harveyi HY01ΔangR (pMMB208), V. harveyi HY01ΔangR (pMMB208-angR), Vibrio anguillarum 775 (pJM1) (pMMB208), and V. anguillarum 96F (pMMB208) grown in AB broth with Cm and 1 lL of 1 mg/mL ferric ammonium citrate (FAC) were spotted on the plates and were incubated at 25°C. Presence of growth halos around spots was checked after 24-h incubation. V. anguillarum 775 (pJM1) (pMMB208) and FAC are positive controls. Vibrio anguillarum 96F (pMMB208) is a vanchrobactin producer and was used as a negative control. (B) Anguibactin production promotes the growth of V. harveyi in iron-limiting conditions. Fifty microliters of overnight culture (adjusted OD600 to 1) grown in 5 mL AB broth with Cm (10 lg/mL) was inoculated into AB broth containing Cm (10 lg/mL) and IPTG (1 mmol/L) (AB) or with addition of 10 lg/mL ferric ammonium citrate (FAC10), 30 lmol/L dipyridyl (DIP30), 60 lmol/L dipyridyl (DIP60), or 90 lmol/L dipyridyl (DIP90). OD600 was measured after 24-h incubation at 25°C. Experiments were repeated five times, and the error bars show standard deviation.

Figure Lengend Snippet: Figure 4. The fatA gene in Vibrio harveyi HY01 encodes the ferric-anguibactin outer membrane receptor protein. (A) The fatA gene is involved in the ferric-anguibactin transport in V. harveyi HY01. V. harveyi HY01ΔangR (pMMB208), V. harveyi HY01ΔangRΔfatA (pMMB208), and V. harveyi HY01ΔangRΔfatA (pMMB208-fatA) were used as indicator strains. DIP (100 lmol/L), IPTG (1 mmol/L), and Cm (10 lg/mL) were supplemented into AB medium with indicator strains. Five microliters of overnight culture of V. harveyi HY01 (pMMB208) and Vibrio anguillarum 775 (pJM1) (pMMB208) and 1 lL of 1 mg/mL ferric ammonium citrate (FAC) were spotted on the plates. Presence of growth halos around spots was checked after 24-h incubation at 25°C. (B) The FatA protein locates on the outer membrane of V. harveyi. Vibrio harveyi HY01ΔangR (pMMB208), V. harveyi HY01ΔangRΔfatA (pMMB208), and V. harveyi HY01ΔangRΔfatA (pMMB208-fatA) were grown in AB medium until exponential phase (OD600 ~0.3). Outer membrane proteins were then extracted using sarkosyl as described in Materials and Methods. Western blots were performed using anti-V. anguillarum FatA polyclonal antibody.

Figure Lengend Snippet: Figure 5. Evaluation of anguibactin production from various strains. Vibrio anguillarum CC9-16ΔfvtAΔfetA was used as an anguibactin indicator strain. EDDA (40 lmol/L) was added into AB media with the indicator strain. Higher concentration of agarose (1%) was supplemented into AB media to reduce swarming of some strains. Overnight culture grown in AB broth was spotted on the plates, and the plates were incubated at 25°C. Presence of growth halos around spots was checked after 24-h incubation. Clear zone around the spot observed in Vibrio harveyi CAIM 513T exhibits swarming but not anguibactin production. Anguibactin production was never detected in anguibactin production negative strains shown in this figure even after incubation for several days. Experiments were repeated three times, and this figure shows a representative.
