Verification of methyl salicylate production from cellular metabolites by wintergreen biosynthetic system We successfully designed, constructed and tested a system for wintergreen odor production from intracellular metabolites (
BBa_J45700). We analyzed cultures for methyl salicylate production using gas chromatography. The wintergreen odor biosynthetic system (
BBa_J45700) produced some methyl salicylate (A). The wintergreen odor generator (
BBa_J45120) in the absence of either the salicylate generator (
BBa_J45320) or exogenous salicylic acid did not produce methyl salicylate (B). The retention time of the methyl salicylate peak from
BBa_J45700 is identical to that of the pure methyl salicylate standard (C). Most
E. coli strains produce indole.
