Two novel antimicrobial peptides purified from the symbiotic bacteria Xenorhabdus budapestensis NMC-10

► Symbiotic bacteria Xenorhabdus associated with entomopathogenic nematodes produced broad-spectrum antibiotics. ► Two novel antimicrobial peptides were purified from Xenorhabdus budapestensis NMC-10. ► Two peptides are linear peptides and with low similarity to published peptide sequences. ► Synthetic peptides inhibit a wide range of plant pathogens and show potential application in plant disease control.
