Effect of heavy metal ions and zinc complex on the dynamics of growth of bacteria Pseudomonas

The problem of wastewater treatment is one of the most pressing issues from the beginning of the century. A special role of the heavy metal s in the pollution of the environment is due to their bio accumulation , transfer through trophic chains, and high toxicity. Currently, advanced technologies for the wastewater treatment had been developed. Natural and cheap biological treatment methods of intensification of the natural processes of organic compounds decomposition by microorganisms under aerobic or anaerobic conditions are promising . Among important processes are nitrification and denitrification. That’s why a g reat attention is paid to the microorganisms that are capable to realize these processes. The processes of interaction of the heavy metals ions and microorganisms are of great interest not only from the standpoint of basic science, but also as a possible use in biotechnological processes.
