Fig. 2From: Analysis of the genomic sequences and metabolites of Serratia surfactantfaciens sp. nov. YD25T that simultaneously produces prodigiosin and serrawettin W2HPLC analysis and structure analyses of the main compounds produced by YD25T. a HPLC analysis of the fraction extracted from YD25T; b The ESI-MS/MS analyses of sw-0 extracted from YD25T; c The structure of sw-0 has been constructed with the positions of bonds whose breakage resulted in the formation of the respective fragments; d The ESI-MS/MS analyses of component sw-5; e The structure of sw-5 has been constructed, and key ROESY and HMBC correlations for sw-5 are shownBack to article page
