ASSESSMENT OF RESISTANCE OF PRO-BIOTIC STRAINS OF MICROORGANISMS TO ESSENTIAL AND TOXIFEROUS HEAVY METALS

Data on the experimental studying of influence of salts of heavy metals on growth of probiotic strains of bacteria of the sort Bacillus are presented in article. During the made experiments it was established that presence of various salts of heavy metals differently influences dynamics of body height of the studied microorganisms. But despite it, the common regularity in influence of the same ion of metal on all studied microorganisms is observed. Presence of ions of lead and iron has the stimulating effect on body height of all studied microorganisms, and presence of ions of a cobalt and cadmium oppresses them body height. Presence of ions of Zincum and manganese does not exert impact on dynamics of growth of the studied strains, the exception makes only B. licheniformis for which Zincum is a growth factor.
