Abstract

The present work is undertaken to studies the important factors affecting the stability of a light emission at immobilized photobacteria, 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 application.
