CA 2171712

A process for the recovery of high purity natamycin from fermentation broth by extraction with methanol is disclosed. In one embodiment the process comprises the steps: (1) adding methanol to a natamycin feed stream comprising at least 2g/L of solid suspended natamycin to form an extraction medium, and maintaining the extraction medium at a temperature of 0-25°C, preferably not over l5°C; (2) adjusting the pH of the extraction medium to 1.0 to 4.5 while maintaining the temperature at 0-25°C for O.5 to 30 hours, but preferably not over O.5 hour when the temperature is l5-25°C; (3) removing solids from the extraction medium to form an extraction liquor; (4) raising the pH of the extraction liquor to 6.0-9.0; and (5) recovering precipitated natamycin.

Procédé de récupération de natamycine de très grande pureté à partir d'un bouillon de fermentation par extraction à l'aide de méthanol. Dans un mode de réalisation, ledit procédé consiste (1) à ajouter du méthanol à un courant de départ de natamycine comportant au moins 2g/L de natamycine solide en suspension pour former un milieu d'extraction, et à maintenir ledit milieu d'extraction à une température de 0-25 C, de préférence ne dépassant pas 15 C; (2) à ajuster le pH du milieu d'extraction entre 1,0 et 4,5 tout en maintenant la température à 0-25 C pendant 0,5 à 30 heures, mais de préférence sans dépasser 0,5 heure lorsque la température est entre 15 et 25 C, (3) à enlever les particules solides du milieu d'extraction pour former une liqueur d'extraction, (4) à élever le pH de la liqueur d'extraction à 6,0-9,0 et (5) à récupérer la natamycine précipitée.
