The Poly(vinyl alcohol)-Immobilized Photobacteria for Toxicology Monitoring

Abstract

The present work is undertaken to studies the important factors affecting the stability of a light emission at immobilized photobacte-ria, and application PVAGs luminous biosensors for biomonitoring of toxicants. The intensity and stability of a light emission is competently controlled by: 1) intensity and persistens of a luminescent cycle using bacterial strain; 2) type of the carrier and the composition of the gel-formation medium; 3) freeze-thawing procedures; 4) physical and chemical conditions of storage and applica-tion.
