Fig. 5

(A) Prodigiosin extracted from H. chejuensis was solubilized in 10 mg/ml DMSO, and the reference value of the sample was compared with the prodigiosin standard from S. marcescens. High-purity prodigiosin was detected at a retention time of ~3 min by HPLC. (B) The molecular weight of prodigiosin (324.2 g/mol) was determined by LC–MS analysis.
