Abstract
The storage conditions have a significant effect on the preservation of the properties and quality of mammoth tusk (MT) after extraction prior to artistic processing. One of the most significant factors in preserving the quality of the raw material is prevention of its biocontamination by environmental microorganisms. They use the organic components of the tusks as a source of nutrition and energy, leading to its early destruction. This paper describes the results of the primary screening of microorganisms-pathogens causing biocontamination of MT samples after long-term storage under various conditions. The sporeforming and mycelium-forming groups of microorganisms were identified. The connection of the detected microflora with the external environment (soil, atmospheric air, indoor air, refrigeration unit) was established. The results will serve as a basis for formulation development to prevent biological damage to mammoth tusk during long-term storage.
Supporting agencies: The research was carried out under the State Assignment of the Ministry of Science and Higher Education of the Russian Federation (№ АААА-А20-120011490003-9).
