investigation of the modeltypeI iterative polyketidesynthase 6-methylsalicylic acid synthase (6-MSAS) in vivo and in vitro. From the fermentation of fungal and bacterial 6-MSAS hosts in the presence of chain termination probes, a full range of biosynthetic intermediates was isolated and characterized for the first time. Meanwhile, in vitro studies of recombinant 6-MSA synthases with both nonhydrolyzable

The present invention relates to colorimetric polydiacetylene (PDA) sensor arrays for detection of analytes and levels thereof in aqueous solutions. In particular the present invention relates to methods of characterizing an aqueous solution for at least one analyte, comprising the steps of a) providing a sensor array comprising at least two different poly-diacetylenes, wherein said poly-diacetylenes are spatially separated and individually addressable, b) contacting said sensor array with a sample of said aqueous solution, c) measuring the colorimetric response of said poly-diacetylenes to the aqueous solution, wherein said poly-diacetylenes are polymerized from a composition comprising one or more diacetylene monomer(s) said poly-diacetylenes are capable of a colorimetric response upon contact with said analyte, and wherein the at least one analyte is selected from the group consisting of an organic molecule with a molecular weight below 2000 g/mol, salts thereof and an inorganic salt.
