Abstract
Official abstract text for this publication.
The lactic acid adsorbent contains at least one substance selected from the group consisting of layered double hydroxide, layered double oxide, weakly basic anion exchange resin having a styrene-bound dimethylamino group, and a strongly basic anion exchange resin.
First claim
Opening claim text (preview).
What is claimed is: 1 . A lactic acid adsorbent comprising at least one substance selected from the group consisting of layered double hydroxide and layered double oxide, wherein the lactic acid absorbent is in contact with a solution containing lactic acid and glucose, to adsorb lactic acid in the solution. 2 . The lactic acid adsorbent according to claim 1 , wherein the solution is a culture solution of cells or microorganisms. 3 . A lactic acid adsorbent comprising at least one substance selected from the group consisting of layered double hydroxide, layered double oxide, and weakly basic anion exchange resin having a styrene-bound dimethylamino group, wherein the lactic acid absorbent is in contact with a culture solution of cells or microorganisms containing lactic acid and glucose, to adsorb lactic acid in the culture solution. 4 . The lactic acid adsorbent according to claim 3 , wherein the weakly basic anion exchange resin is of high porous type or of MR type. 5 . The lactic acid adsorbent according to claim 1 , wherein the amount of addition thereof to the solution is more than 0.0005 g/mL and less than 0.2 g/mL. 6 . A method for removing lactic acid, the method comprising bringing the lactic acid adsorbent described in claim 1 in contact with lactic acid.
