Bacillibactin
Based on 1 Customer Validation
Bacillibactin (Corynebactin) is a cyclic tricatecholate siderophore. Bacillibactin’s primary function is to facilitate bacterial iron acquisition by chelating iron ions (Fe3+) from the environment, thereby aiding bacterial survival under iron-limited conditions. Bacillibactin exhibits direct antimicrobial activity, such as inhibition of the growth of the producing bacteria Pseudomonas aeruginosa and Aeromonas veronae, as well as plant pathogens such as Pseudomonas syringae.Bacillibactin can be used in antibacterial and antifungal research.

Biological Activity
Bacillibactin demonstrates strong inhibitory activity against Pseudomonas aeruginosa and Aeromonas veronii[1].
Bacillibactin significantly inhibites the growth of P. syringae pv. tomato, Pst under iron starvation conditions and inhibits the growth of a wider range of fungal pathogens (Such as Fusarium, Rhizoctonia, Aspergillus, Verticillium, etc.)[3].
Bacillibactin (10 μM) shows an inhibition rate of less than 20% against two human cancer cell lines (HepG2 liver cancer cells and MCF7 breast cancer cells), indicating that it does not exhibit significant in vitro anti-tumor activity[4].
