Application of Biosorption in the Production of Innovative Feed Supplements: A Novel Method

Abstract

A novel method of biosorption was used in the production of innovative feed supplements using microelements based on common feed ingredients (triticale, oat, barley, corn beans, soy beans, wheat and rye). A new insight into the application of biomasses as the biological carriers of microelements was proposed to reduce the production costs of new supplements. Chromium(III) ions were used as a model cation in kinetic and equilibrium studies. The experimental conditions were as follows: pH 5.0, temperature 25 °C, biomass concentration 1 g l −1 . The reaction mixture attained the equilibrium point within minutes and all of the biomasses demonstrated good biosorption properties. Barley had the highest biosorption capacity (45.9 mg g −1 ), whereas wheat (19.1 mg g −1 ) had the lowest. Costs of the producing new supplements were related to the biosorption of microelement ions and drying of enriched biomass. However, no additional costs were associated with obtaining and preparing additional raw materials.
