Abstract
The invention provides a feedstuff additive based on a fermentation broth obtained by the fermentation of D-pantothenic acid producing microorganisms. The broth contains D-pantothenic acid, one or more salts of D-pantothenic acid, or mixtures thereof. Conversion of the broth to a solid, free-flowing form is achieved by drying or granulation
Claims15
Animal feedstuff additives comprising:
- a) at least one member of the group consisting of D-pantothenic acid and D-pantothenic acid salts;
- b) 0 to 100% of a biomass formed during fermentation in a fermentation broth of microorganisms which produce D-pantothenic acid, the microorganisms being selected from the group consisting of Corynebacterium glutamicum, Brevibacterium lactofermentum and Saccharomyces cerevisiae;
- and
- c) dissolved ingredients in the fermentation broth,
- wherein said feedstuff additives are present in a solid, finely divided or granulated, free-flowing form.
A process for preparing feedstuff additives containing at least one member of the group consisting of D-pantothenic acid and D-pantothenic acid salts comprising
- a) obtaining a D-pantothenic acid-containing fermentation broth formed during fermentation of microorganisms selected from the group consisting of Corynebacterium glutamicum, Brevibacterium lactofermentum and Saccharomyces cerevisiae;
- b) optionally, at least partially removing a fermentation biomass, from the fermentation broth;
- c) adding a hydroxide or oxide of an alkaline earth or alkali metal to the broth of step b) to form a solution;
- and
- d) drying the solution of step c).
A process for preparing feedstuff additives containing at least one member selected from the group consisting of D-pantothenic acid a sodium salt of D-pantothenic acid, a potassium salt of D-pantothenic acid, an ammonium salt of D-pantothenic acid, a magnesium salt of D-pantothenic acid and a calcium salt of D-pantothenic acid comprising
- a) obtaining a D-pantothenic acid-containing broth from fermentation of a microorganism;
- b) optionally, at least partially removing a fermentation biomass from the fermentation broth;
- c) optionally, concentrating the fermentation broth of step b);
- and
- d) drying to obtain the feedstuff additive.
