US 2024/0254528 A1 · AQUEOUS BIOLOGICAL SYSTEMS WITH REDUCED PHOSPHATE LEVELS AND METHODS OF REDUCING PHOSPHATE LEVELS

Abstract

The technology disclosed in this specification pertains to methods of reducing phosphate levels in aqueous preparations containing phosphate with the admixture of first and second compounds containing cations which can bind phosphates. In any embodiment, the phosphate level is reduced to less than about 80 wt. %. The technology also relates to methods of collecting and sequestering phosphate in aqueous preparations. The technology also relates to the collection or removal of phosphate while minimizing the loss of desired target molecules, such as saccharides. In any embodiment, the aqueous preparation is maintained within certain pH ranges during the admixture of the first and second compounds, to maintain the stability of certain target molecules, such as saccharides, during the reduction of the phosphate. Also disclosed is an aqueous preparation having precipitated phosphate or reduced phosphate levels, particularly aqueous preparations also maintaining levels of desired saccharides.

Dependent claims

A method of reducing phosphate in an aqueous preparation comprising:

a) obtaining the aqueous preparation comprising phosphate and a target molecule;
b) combining the aqueous preparation with a first compound and a second compound, to provide a treated preparation, wherein both compounds comprises a polyvalent cation;
c) mixing the treated preparation at sufficient temperature and for sufficient time for the phosphate and the compounds to form a precipitate, to provide a reduced-phosphate preparation;
and
d) optionally, removing the precipitate from the reduced-phosphate preparation;
wherein the aqueous preparation maintains a pH between about 4 and about 10 and the treated preparation has a pH between about 4 and about 10;
wherein the reduced-phosphate preparation retains a portion of the target molecule;
wherein the target molecule is a saccharide selected from the group consisting of arabinose, lyxose, ribose, xylose, ribulose, xylulose, allose, altrose, galactose, glucose, gulose, idose, mannose talose, fructose, allulose, sorbose, tagatose and mixtures and combinations thereof.
