[EFFECT OF MICROSCOPIC FUNGI ON COMPONENT COMPOSITION OF RUBBER SCN-18].

Resistance to the action of microscopic fungi of the material SCN-18, which had been characterized by high resistance to microscopic fungi was idefenited. It has been noted that in the case of using of test cultures of fungi isolated from the rubber substrates, the intensity of damage of the SCN-18 was higher than in the case of using of species proposed by GOST 9.049-91.

[Destruction of the solid-cast rubber tyres by microscopic fungi].

Resistance to the action of standard test-cultures of fungi (in accordance with GOST 9.049-91 of the former U.S.

[Contamination of solid-cast rubber tires by microscopic fungi].

The main peculiarities of fungal resistance of two types of unit cast rubber tires of domestic manufacture have been investigated. Rubber tires which contained synthetic plasticizer were non-resistant to fungal contamination in contrast to ones with natural plasticizer. Using the method of confocal laser-scanning microscopy, it was shown that inner layers of two types of rubber tires were contaminated with fungal mycelium.

[Species specificity of fungi isolated from the affected rubber tires and their components].

The mycobiota of the rubber technical wares, containing different plasticizers (natural and synthetic) have been investigated. Violation of production technology and storage conditions of the staggered rubber tires, caused their deterioration by the microfungi. Twenty seven (27) species of micromycetes, related to 16 genera were isolated from the surface and internal layers of such objects and their components.
