A series of sorbents containing various amounts of borate groups were prepared by chemical immobilization of
P-aminoethylphenylboric acid on a copolymer- treated organosilane spacer glass plates. It was found that
baker's yeast cells selectively adhered to these supports. Yeast cells stained with procion red HE-3B formed
denser and more stable layer on the copolymer-grafted supports compared onto supports modified with
phenylboric acid via a organosilane spacer. Adhesion of yeast cells to boronate-containing polymer fixed on
solid support in presence of different concentration of fructose, a sugar with high affinity to boronates, was
