Project summaryEstimated project duration is two years.
Microbiota assays will be made on both the exterior and interior walls of the buildings of the State Hermitage, and on pieces of sculpture. The Hermitage buildings are representative of structures in the historical center of Saint Petersburg, and the project results will be applicable to most old residential and museum buildings in the city.
Samples of materials will be systematically collected under different environmental conditions. Then, the samples will be cultivated on nutrient media to isolate fungi – potential biodestructors.
The effect of selected types of electromagnetic (EM) radiation on fungi will be studied for a wide range of modes and doses under laboratory conditions; the vitality of micromycetes will be determined by biological and other methods; thresholds and ranges of pernicious action of gamma and X-rays, microwaves, optical coherent and non-coherent radiation on fungi will also be determined.
Theoretical models of the biological effect of EM factors on fungi will be constructed. Based on them, we will identify the most efficient kinds of radiation and regimes.
The unique fund of fungi, held at the disposal of the project authors, will allow them to carry out experiments on test-specimens. This will considerably accelerate project implementation and will ensure the reliability of obtained results.
Following the experiments with model test-specimens, an investigation of EM radiation effect on fungi isolated from the Hermitage objects will be carried out.
A depository for long-term storage of classified samples of materials will be provided, to ensure the continuity of mycological monitoring of the museum.
In the final phase of the project we will experimentally investigate the EM effect on fungi in their natural growth conditions.
As a result of the study, we plan to identify biodestructors-fungi, compose a computer-based catalog on them, and determine the ranges for the chosen EM radiation factors ensuring destruction of micromycetes, without destroying pieces of art and architecture. Also, we will provide specifications on technologies and equipment for antifungal EM treatment of pieces of sculpture and architecture.
Computer-based cataloging will be conducted according to key fungus features: cytomorphological, physiological, biochemical, and other characteristics.
The effect of EM factors, fatal for micromycetes and safe for materials of exhibits and architectural memorials, will provide the basis for design and development of treatment facilities.
