Oxidative stress and bioluminescence in the fungi Gerronema viridilucens and Mycena lucentipes. Antioxidant defenses Fungi bioluminescence Glutathione Metal toxicity Oxidative stress Phenol toxicity.

Ligninolitic fungi also produce these oxidizing species also during the lignin degradation process. The bioluminescent species Gerronema viridilucens and Mycena lucentipes were studied aiming to establish a correlation between the temporal profiles of bioluminescence, cellular viability and antioxidant defense enzymes and ligninolitic enzymes in mycelium and fruiting bodies.

Chemical toxicants such as metals and fungoe were here found to affect light emission, cellular viability, antioxidant defenses and cellular respiration enzymes when administered to G.

Different species of fungi exhibit different characteristics linked to light emission and antioxidant defenses. Differences in light emission displayed by different species do not resume to fruiting bodies, but the light profile and hioluminescentes can also vary in the mycelia.

This may explain the irreproducibility of the light profile from M. The cellular viability of both species varies with time, G.

Bioluminescencia

The enzymatic data pointed to higher activities in mycelium than in fruiting bodies, probably due to a main reproductive function of the latter, whereas the metabolic activities are prevalent in the mycelium. Ligninolytic enzymes exhibit low activities in the extracts of fungus samples, probably because they are extracellular degradation enzymes.

The inhibition effect of phenols and metals copper and cadmium on mycelium viability reinforces the notion that cellular oxidative damage hampers bioluminescence emission. Redox active copper and heavy metals cadmium were found to display higher impact on antioxidant defenses than phenols phenol and biolyminescenteswhich are expected to be promptly metabolized and excluded by principally glutathione S-transferase GST.

Notably, a metabolic correlation between bioluminescence inhibition and antioxidant defenses was unveiled by the present work. Regarding the metals, glutathione was found to be a crucial antioxidant, both to eliminate peroxides when in the presence of copper, and to act as a cadmium chelating agent. Under normal conditions, the bioluminescence system, the antioxidant defenses and the cellular respiration sets cooperate through the common demand of reducing power of NAD P H.

Under chemical stress, the NAD P H flux would be deviated from bioluminescence, to principally sustain the antioxidant defenses and cellular respiration, essential for the protection, maintenance and reproduction of the organism.
