RESPIRATION OF GANODERMA LINGZHI FUNGUS DURING ITS GROWTH
Abstract
We are interested in mushrooms mainly for two reasons: for the substances they contain and for their natural abilities. Therefore, they are used as food, as sources of health-promoting and medicinal substances, and as agents for restoring, strengthening, and revitalizing the environment. These are the main reasons why we must continually deepen our knowledge of mushrooms and use them wisely. Among the mushrooms used in remediation processes is Ganoderma lingzhi, originally from China. The physiological activity of fungi during growth on oak and beech chip substrates under various climatic conditions was evaluated based on measurements of fungal respiration. CO2 production was measured over five months using a closed chamber with infrared gas analysis probes (IRGA). We obtained unique data on fungal activity -specifically on the intensity and dynamics of respiration during growth - through objectively measured CO2 production values. The initial growth stage involving mycelial expansion is metabolically demanding and thus produces higher CO2 fluxes. A reduction in CO2 production before fruiting indicates a possible latent metabolic phase, and fruiting itself was not associated with increased respiration.
