Selective and stable adhesion of Yeast cells to Boronate-containing Polymer Grafted to glass Supports

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