Fungicidal toxins from biocontrol bacteria

摘要

A biocontrol bacteria, Bacillus cereus ATCC 53522, has been found to naturally synthesize two antibiotics, here designated zwittermicin A and antibiotic B. Zwittermicin A is a 396 dalton linear aminopolyol, a class of metabolite previously unknown in B. cereus. Antibiotic B is an aminoglycoside. Both antibiotics exhibit inhibitory activity on many fungal and bacterial pathogens.
