CA 2188434

The invention relates to the use of a phosphate glass as a phosphorous source in the media of high cell density bacterial fermentation processes in order to reduce metallophosphate precipitation reactions. The methods of the invention demonstrate a practical method for controlling levels of metallophosphate precipitation in both the nutrient media and the fermentor which also result in increased cell densities and are useful in a variety of high cell density bacterial fermentation processes.

L'invention concerne l'utilisation d'un verre phosphaté comme source de phosphore dans les milieux de procédés de fermentation bactérienne à haute densité cellulaire, afin de réduire des réactions de précipitation au métallophosphate. Les procédés de l'invention présentent un procédé pratique de réduction des niveaux de précipitation au métallophosphate à la fois dans les milieux nutritifs et dans la cuve de fermentation, ayant également pour résultat d'accroître les densités cellulaires, ils sont également utiles dans divers procédés de fermentation bactérienne à haute densité cellulaire.
