| Popis: | It has been studied enzymatic activity in cells of some microorganisms-symbionts under toxic effect of the most common in the environment biocide pentachlorophenol (PCP) and protective ability of natural sorbent clinoptilolite, its deposits are only more than 1 billion tons in the West Ukraine (Zakarpattia). It has been shown that the cells of pure ruminal strains (Butyrivibrio fibrisolvens, Streptococcus bovis and Megasphaera elsdenii) are different by the activity of the seven key intracellular enzymes. Under effect of a small dose of PCP (40 mM), activity of the studied enzymes significantly is reduced in cells of very sensitive to the biocide bacterium B. fibrisolvens. In the cells of less sensitive to toxicant strains of bacteria (S. bovis and M. elsdenii), activity of all enzymes is significantly reduced only under effect in 2.5 times higher dose of PCP. Adding clinoptilolite into bacterial incubation medium with pentachlorophenol in the above doses significantly increases the enzymatic activity in the cells of all investigated pure strains of microorganisms-symbionts of rumen. |
