Endophytic Bacillus sp. CY22 from a Balloon Flower (Platycodan grandiflorum) Produces Surfactin Isoforms

Surfactin is a mixture of cyclic lipopeptides built from variants of a heptapeptide and a beta-hydroxy fatty acid produced by several strains of Bacillus sp. Surfactin isoforms produced by endophytic Bacillus sp. CY22 from a balloon flower were isolated and characterized. It was found that the purif...

Zusammenfassung:Surfactin is a mixture of cyclic lipopeptides built from variants of a heptapeptide and a beta-hydroxy fatty acid produced by several strains of Bacillus sp. Surfactin isoforms produced by endophytic Bacillus sp. CY22 from a balloon flower were isolated and characterized. It was found that the purified surfactin had three isoforms with protonated masses of m/z 1,008, 1,002 and 1,036, and different structures in combination with Na, K, Ca ions using MALDI-TOF MS,ESI-MS/MS, and ICP MS, respectively
