ABSTRACT:
The present process concerns the production of glutamic acid or glutamate. The process of the present invention includes the following steps. Glutamine or glutamic acid rich proteins are hydrolysed. Optionally, the glutamic acid is converted to glutamate and the glutamate is isolated. The protein hydrolysate or the glutamate depleted protein hydrolysate is added to the feedstock of a glutamic acid fermentation in such an amount that the protein hydrolysate forms the major carbon and nitrogen source. After fermentation the glutamic acid is converted to glutamate and the glutamate is isolated.
