Аннотация: The peroxidase and catalase activities in the mycelium of luminous basidiomycetes Armillaria borealis and Neonothopanus nambi in normal conditions and under stress were compared. An increase in the luminescence level was observed under stress, as well as an increase in peroxidase and catalase activities. Moreover, the peroxidase activity in extracts of A. borealis mycelium was found to be almost one and a half orders of magnitude lower, and the catalase activity more than two orders of magnitude higher in comparison with the N. nambi mycelium. It can be suggested that the difference between the brightly luminescent and dimly luminescent mycelium of N. nambi is due to the content of (HO2)-O-2 or other peroxide compounds.

luminescence -- luminous higher fungi -- mycelium
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 Panellus 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.

Кл.слова (ненормированные):
Bioluminescence -- culture of luminous mycelia -- kinetics of luminescent -- reaction -- light emitting wood -- luminous fungus
Аннотация: In studies of fungal bioluminescence, not only fruiting bodies and spores of the fungus, but also samples of luminescent wood, leaf litter or soil may need to be used to derive pure mycelial culture. This study describes an approach to isolating the culture of luminescent fungal mycelium from samples of light-emitting wood found on Borneo Island in November-December 2013. A GelDoc XR Imaging System (Bio-Rad Laboratories, Inc., U.S.) was used for the first time to monitor luminescence and select luminous samples. This study shows that for successful isolation of the culture of luminescent mycelium out of the luminescent wood found in the forest, it is imperative to keep the samples moist (mycelium alive until there is water), while immediate and aseptic delivery of the samples to the laboratory is not a crucial condition (inner layers of wood is "sterile"). Investigation of the growth features of the isolated mycelium in various growing conditions revealed some peculiar properties of its luminescence in comparison with the known luminescent cultures of basidiomycetes. When grown on solid nutrient media, mycelium exhibits low growth rates, long-lasting luminescence (140 days or longer), and emergence and disappearance of local zones with high levels of light emission. Mycelium produced in submerged culture does not emit light, and this effect must be caused by the absence or a very low level of the luminescent reaction substrate in the biomass. The luminescence system isolated from mycelial biomass did not induce luminescent reaction in vitro upon the addition of NADPH (recording intensity is 60 100 URL/sec). We found that enzymes of the luminescence systems isolated from mycelium pellets retained their activity and catalyzed luminescent reaction when a hot extract of the luminous fungus Armillaria sp. (IBSO 2360) was added (near 1900 URL/sec). The same effect was obtained after addition of hot extracts from the fruiting bodies of nonluminous higher fungi Pholiota squarrosa, Cortinarius sp., Hypholoma capnoides and Chroogomphus rutilus (near 3500 URL/sec). The pure culture of luminescent mycelium has been registered in the Culture Collection of IBP SB RAS as IBSO 2371; now it can be used for various in vivo and in vitro studies, including identification of the fungus.

Comparative evaluation of total peroxidase and catalase activities during light emission of luminous fungus Neonothopanus nambi / O. A. Mogilnaya, N. O. Ronzhin, V. S. Bondar // Mycosphere. - 2016. - Vol. 7, Is. 4. - P499-510, DOI 10.5943/mycosphere/7/4/9 . - ISSN 2077-7000

Basidiomycetes -- Hydrogen peroxide -- Luminescence -- Stress
Аннотация: Submerged cultivation of luminous fungus Neonothopanus nambi under orbital stirring causes formation of pellets with smooth or rough surfaces. The experiments showed that luminescence of the pellets washed in water increased considerably. Previous studies suggested possible participation of peroxidases in the light emitting reaction. In this study, oxidative azo coupling reaction accompanied by formation of chromogen was used to evaluate peroxidase activity in vivo, in brightly luminescent pellets and in pellets with low luminescence intensity (dim ones). Staining of the brightly luminescent pellets took a few minutes, and their staining intensity was several times higher than that of the dim pellets. From the results of in vivo experiments it was concluded that the bright pellets differed from the dim ones in the production of hydrogen peroxide, or, possibly, other peroxides. Measurements of total peroxidase and catalase activities in pellet extracts also showed an increase in enzyme activities along with an increase in luminescence intensity of native pellets. However, results of the in vitro experiments do not definitively suggest a direct relationship between luminescence and activity of these enzymes. We assume that luminescence of this fungal species may be an additional way to neutralize peroxide compounds under stress. © Guizhou Academy of Agricultural Sciences.

Аннотация: Cold extracts with high activities of enzymes of luminescent reaction were prepared from mycelia of luminous fungi Armillaria borealis IBSO 2328, Mycena citricolor IBSO 2331, and Neonothopanus nambi IBSO 2391. The authors describe techniques of preparing cold extracts with high levels of luminescence from mycelial biomass of different species of luminous basidiomycetes. The investigation of cold extracts showed that in experiments with freezing and thawing of the samples as well as in experiments with lyophilization followed by dissolution of the dry samples, the levels of enzyme activity were high, with in vitro luminescence exhibited after addition of NADPH and the hot extract containing the substrate. High activity levels of the enzymes of luminescent reaction were measured in lyophilized cold extracts stored over three years. In lyophilized preparations, the enzymes of luminescent reaction had high thermostability, even when dry preparations of cold extracts were exposed to a temperature of 100°C for 60 minutes. © Beijing Academy of Agriculture and Forestry Sciences.

Morphological properties and levels of extracellular peroxidase activity and light emission of the basidiomycete Armillaria borealis treated with beta-glucosidase and chitinase / O. A.

Аннотация: The study estimates morphological properties and levels of extracellular peroxidase activity and light emission of mycelium of the basidiomycete Armillaria borealis IBSO 2328 treated with beta-glucosidase and chitinase. Mycelium incubated with the enzymes shows considerable morphological changes and indications of osmotic shock. Injuries observed in the cell envelope of the fungal hyphae are primarily attributed to the partial (in the beta-glucosidase treatment) or complete (in the chitinase treatment) disintegration of the melanin layer on the surface of the cell wall. Changes in the cell wall of hyphae are accompanied by release of extracellular peroxidases of the fungus into the incubation medium and an increase in light emission relative to the luminescence of the control pellets. We assume that higher level of luminescence of the enzyme-treated mycelium samples could be related to the disintegration of the surface pigment layer of the hyphae and the partial loss of extracellular peroxidases. The data obtained confirm the previously proposed hypothesis in which light producing reaction of the fungus may be an additional way to neutralize active oxygen radicals under stress.

Estimating levels of light emission and extracellular peroxidase activity of mycelium of luminous fungus Neonothopanus nambi treated with ?-glucosidase / O. A. Mogilnaya, N. O. Ronzhin, V. S.

Basidiomycetes -- Cell wall -- Luminescence -- Polysaccharide sheath
Аннотация: The present study estimates the level of extracellular peroxidase activity and light emission intensity of mycelium of luminescent basidiomycete Neonothopanus nambi treated with ?-glucosidase. A hypothesis has been proposed that treatment with ?-glucosidase may trigger biochemical mechanisms of activation of ROS (primarily hydrogen peroxide) generation in N. nambi mycelium. The results obtained indicate that the enzyme causes partial disintegration of the slimy sheath of fungal hyphae and intracellular matrix, which leads to release of the extracellular peroxidases to the incubation medium. Mycelial cells treated with the enzyme reach the peak of their luminescence sooner. It has been assumed that partial loss of extracellular peroxidases, as important enzymes of antioxidant defense, may be compensated for by an increase in the level of light emission by the fungus. © 2018 Beijing Academy of Agriculture and Forestry Sciences.

Two forms of substrate for the bioluminescent reaction in three species of basidiomycetes / A. P. Puzyr [et al.] // Mycol. - 2019. - Vol. 10, Is. 2. - P84-91, DOI 10.1080/21501203.2019.1583688 . - ISSN 2150-1203

Cold and hot extracts -- culture liquid -- enzymatic system -- hispidin -- luminous fungi -- substrate of luminescent reaction
Аннотация: The luminescent response of the enzymatic system of Armillaria borealis on the cold and hot extracts from cell-free culture liquids of Inonotus obliquus, Pholiota sp. and A. borealis was examined. The greatest influence on the light emission produced by the luminescent system of A. borealis was provided by the temperature at which the probes were prepared for assay. Boiling a culture liquid on water bath for a few minutes promoted a multifold increase in the luminescence. The results of luminescence assay suggest that the substance involved in the bioluminescent reaction in higher fungi is presented in culture liquids and mycelia in two forms. In one form, it is ready to interact with the enzymatic system and in the second form, it becomes accessible for the reaction after heat treatment. The pool of thermoactivated substance was found to be much large than the amount of the ready accessible one. We suggest that predecessors of hispidin, which is fungal luciferin precursor, are responsible for this phenomenon. They are not involved in bioluminescence at their original state and are converted into the substrate under the influence of high temperature. © 2019, © 2019 The Author(s).

Аннотация: A comparative evaluation of the level of extracellular peroxidase activity and light-emission intensity of the mycelium of the luminescent basidiomycete Neonothopanus nambi in the presence of ?-glucosidase was performed. The enzyme activity damages the hyphae of the fungus leading to osmotic imbalance, partial degradation of the mycelium, and release of extracellular peroxidases into the incubation medium. The presence of ?-glucosidase reduces the time necessary to reach the maximum luminescence. Putative biochemical mechanisms that underlie the stimulation of reactive oxygen species formation (first and foremost, of hydrogen peroxide) in the N. nambi mycelium in the presence of ?-glucosidase are proposed. © O.A.

Detecting bioluminescence conditions in fruit bodies of two species of Armillaria basidiomycetes / A. P. Puzyr, A. E. Burov, V. S.

Аннотация: Mycelia of various Armillaria fungi are bioluminescent while the fruit bodies do not emit light. The presence in fruit bodies of Armillaria species of enzymes involved in the fungal bioluminescence was investigated by treating them with an exogenous analogue of the substrate for the light-emitting reaction. For this, hot extracts from nonluminous fungus Pholiota squarrosa were used. Upon spraying the pristine and transversely cut fruit bodies with the extracts, light emitting regions of different intensity were revealed. This suggests that the fruit bodies of the studied species are nonluminous due to lack of the substrate for light luminescent reaction. The prolonged incubation of the fruit bodies in water elevated the bioluminescence level. A possible mechanism which can explain this phenomenon is discussed. © 2021 Institute of Physics Publishing.
