  1. Only compounds with a good match to compounds characterized in the literature are listed. Compounds were detected using LC/MS–MS. Values are the mean of two experiments with standard error. Prodigiosin and serratamolide values are area counts per second adjusted for dilution and normalized by protein concentration of cellular lysate [(counts/s)/(µg/mL)]. Total protein concentration (µg/mL) was of cell lysate resulting from sonication of strains N4-5 or Tn246. SW1, serrawettin W1; N/A, not applicable
