Disclosed herein are new strains of Propionibacterium and methods for the biosynthetic production of propionic acid.

Propionibacterium strains for the production of propionic acid

A composition includes alysate and cellular components and residual media remaining from a fermentation process that produced abiomass and thelysate. The cellular components may include one or more beta-glucan polymer chains having a molecular weight of 1.2 to 580 kilodaltons (kDa).

A process to prepare propionic acid comprises preparing a fermentation broth of water; at least 30 weight percent hydrolyzed corn mash solids, hydrolyzed sugar cane mash solids, or a combination thereof, based on the combined weight of the fermentation broth as a whole; and; without including the typical, frequently very costly supplementation with vitamin and mineral packages. Surprisingly, these mash solids, which must often be disposed of following syrup production, are capable of supplying the nitrogen, micronutrients, vitamins and minerals known to be needed forfermentation, making their sole or significant use as fermentation mediums far more economical and therefore desirable than other fermentation mediums which require supplementation.
