Abstract
The effect of nutrient medium composition on the release of bacteria acting on the surface of zinc, hydrogen peroxide as a product of oxygen biotransformation electron-transport circuit components of bacteria were studied. It is shown that cultivation of gram-positive bacteria Bacillus subtilis and Clostridium spp. on a meat peptone agar medium was accompanied by the formation of hydrogen peroxide in a smaller amount as against bacteria when cultured on glucose mineral medium. Impact of gram-negative bacteria Pseudomonas aeruginosa and Pseudomonas fluorescens on zinc surface in favorable conditions for the vital activity leads to the high hydrogen peroxide formation.
