Russian experts create a solution using bacteria to protect antiques and exhibits from mold

Experts from the Russian National Research Center (Kurchatov Institute) used bacteria to produce a solution with silver nanoparticles, which allows museum exhibits to be protected from mold and germs.

This solution can be used to paint statues and monuments damaged by fungi or in which microorganisms nest. It can also be added to dyes and varnishes used in restoration operations.

It is noteworthy that the synthetic compounds currently used to remove mold from exhibits are not safe for the surrounding environment and are not always effective. As for the inventors of the new solution, they found an environmentally friendly way to prevent the proliferation of fungi and microbes, which includes using iron, zinc, and vital silver nanoparticles, which they obtain from the cells of the Shewanella oneidensis MR-1 bacteria, which are capable of synthesizing metals.

“Bio-nanoparticles are a new word in the protection of cultural heritage sites,” says Olga Zhuravlyova, chief researcher at the Center’s Laboratory of Biotechnologies for Environmental Protection. “We found that they effectively inhibit the growth of various types of microorganisms and molds. The biological method used to obtain them is also distinguished.” “It is environmentally friendly, technologically simple, does not consume much energy, is easily scalable, and its properties are comparable to chemically synthesized nanomaterials.”

The innovative solution can also be used as a component of covering, finishing and building materials as well.
