The samples of Luxene HDPE 2050, (MPB) and Borcoat HE 3450, (Borealis) polyethylene and samples of three systems applied to the pipe were resistant to the bacteria Pseudomonas aeruginosa, Pseudomonas stutzeri, Pseudomonas mendocina and Desulfovibrio desulfuricans. The decrease in the content of viable bacteria 100-1000 times during the experiment testified to the depletion in the environment of power sources and processes of autolysis of bacterial cells.
