Abstract
Process for obtaining l-5-hydroxy-tryptophan, essentially by microbiological fermentation of l-tryptophan or l-acetyltryptophan, by the action of non-pathogenic microorganisms selected from the families of the micrococcaceae, pseudomonadaceae, corynebacteriaceae, enterobacteriaceae and bacillaceae, characterized in that said fermentation is conducted at temperatures between 25º and 40ºC and ph of 6 to 8, feeding the crop an air flow between 1 and 5 liters/minute, in the presence of fe ions that increase the yield of fermentation and of ascorbic acid. Fermentative process, whose fe and ascorbic acid components are incorporated into the process at a time close to the end of the main growth of the microorganism, controlling the growth of the substrate by thin layer chromatography and following the fermentation, a separation of the bacterial cells of the culture broth by centrifugation or filtration and fixing of the l-5-hydroxytryptophan formed on a cation exchanger in the h form, from which the eluate is eluted and purified, once concentrated, with gel-dextran.
