Abstract:
Cultures of the zeaxanthin-producing bacterium Paracoccus species strain PTA-3335 (formerly Flavobacterium) were grown with supplements of (13)C-labeled glucose. Zeaxanthin was isolated and analyzed by (13)C NMR spectroscopy. The data showed that the isoprenoid precursors of zeaxanthin were biosynthesized via the mevalonate pathway. The microorganism was found to utilize glucose mainly via the Entner-Doudoroff pathway.
