REACTION CALCIUM CHLORIDE EXOPOLYMERIC ALGINATE MATRIX IS FORMED BY STRAINS PSEUDOMONAS AERUGINOSA

Studied the reaction of calcium chloride solution with exopolymeric alginate matrix formed by strains of the bacterium Pseudomonas aeruginosa. During the experiment, were used 38 strains of the bacterium Pseudomonas aeruginosa including 4 reference strain. Culturing the bacterium Pseudomonas aeruginosa was performed in a liquid synthetic medium in which the matrix is formed exopolymeric and belt-broth. Cultivation was performed in an incubator at 37 °C. The results were evaluated every 24 hours within 96 hours. As a result of experiments it was found that by adding a 10 % solution of calcium chloride 1 ml of bacterial cult liquid synthetic medium falls white fl occulent colloid calcium salts of alginic acids. And when added in a 10 % solution of calcium chloride 1 ml of bacterial culture broth belt coming any precipitation was not observed.
