Аннотация: There are higher fungi that emit visible light; however, little is known about their requirements for good growth and bright luminescence. Knowledge of these requirements is extremely important for maintaining fungal cultures in laboratory conditions and preparation of luminous mycelia for research purposes. Luminous higher fungi PПоказать полностьюanellus stipticus, Armillaria sp. and Neonothopanus nambi isolated from different climatic areas and maintained in CCIBSO 836 (Collection of IBP SB RAS, Russia) were used for experiments. Techniques for static and submerged cultivation of mycelia of higher fungi have been developed and optimized for the production of samples of aerial and globular mycelia with prolonged and stable luminescence. We investigated the growth characteristics and luminescence of mycelia cultivated in/on different nutrient media, and the effects of deionized water and mechanical damage on the light emission of mycelia. An increase in luminescence intensity of fungal mycelia can be obtained during cultivation of fungi on a nutrient medium with a certain composition. A significant increase in light emission from N. nambi mycelium can also be obtained after its incubation in water and mechanical damage. The light emission from N. nambi mycelium was greatly enhanced after these treatments, in contrast to the mycelia of Armillaria sp. or P. stipticus. Cultivation conditions that enable growing mycelia with high levels of luminescence will expedite further studies to gain a better understanding of fungal bioluminescence.
