Abstract Background Dodecanedioic acid (DDA), a typical medium-chain dicarboxylic fatty with widespread applications, has great synthetic value and huge industrial market demand. Currently, sustainable, eco-friendly efficient process is desired for dodecanedioic production. Results Herein, multi-enzymatic cascade was designed constructed the production of DDA from linoleic based on lipoxygenase pathway in plants. The composed lipoxygenase, hydroperoxide lyase, aldehyde dehydrogenase, unidentified double-bond reductase E. coli main reactions, as well NADH oxidase cofactor recycling. four component enzymes involved were co-expressed , together endogenous . After optimizing reaction conditions rate-limiting step, 43.8 g L − 1 d obtained by whole-cell one-pot starting renewable acid. Conclusions Through engineering system co-expressing enzymes, sustainable biosynthesis route set up which afforded highest space time yield among current artificial routes derived LOX-pathway, productivity achieved here ranks second research progress biosynthesis.

To tackle the ageing phenomena of precious artworks, binding media have been increasingly explored in cultural heritage. When siccative oils are employed as paint media, medium-chain dicarboxylic fatty acids (DFAs), also known dioic acids, generated from unsaturated acyl chains by hydroxyl and hydroperoxyl radicals during drying process. Hitherto, gas-chromatography coupled with mass spectrometry (MS) has represented foremost technique for investigation DFAs upon proper derivatization reactions, yet current work aims to introduce an alternative approach based on reversed-phase liquid chromatography, negative-ion-mode electrospray ionization high-resolution/accuracy MS tandem MS. Painting reconstructions linseed oil mixed common inorganic pigments such chrome yellow cadmium red were investigated their content suberic (C8), azelaic (C9), sebacic (C10), undecanedioic (C11) acids. For identification these unbounded species, retention time data followed confirmation accurate m/z measurements a detailed analysis fragmentation patterns via used. estimate quantity DFAs, samples spiked suitable internal standard before lipid extraction. This analytical strategy was successfully applied three 50-year-old paintings, using only few milligrams (i.e., 25–50 mg). Notably, difference DFA profiles observed within artwork, exhibiting relatively lower compared ones. Spectroscopic techniques revealed alterations relevant chemical composition Likely chromate ion, component pigment, undergoes oxidation which may hinder generation Fenton reaction, iron catalyst naturally occurring is potentially affected.
