Characterization and antifungal activity against Pestalotiopsis of a fusaricidin-type compound produced by Paenibacillus polymyxa Y-1

In this study, an endophytic bacterium was isolated from the stem of Dendrobium nobile and identified as Paenibacillus polymyxa Y-1. The active metabolites of this bacterium were isolated and identified as fusaricidin compounds. The mechanism of fusaricidin compounds on pathogenic fungi (Pestalotiopsis) was investigated by using proteomics.240
