Аннотация: The possibility of the development of the solid phase bioluminescent biotest using aerial mycelium of luminous fungi was investigated. Effect of organic and inorganic toxic compounds (TC) at concentrations from 10 -6 to 1 mg/ml on luminescence of aerial mycelia of four species of luminous fungi-Armillaria borealis (Culture Collection of the Institute of Forest, Siberian Branch, Russian Academy of Sciences), A. mellea, A. gallica, and Lampteromyces japonicus (Fungi Collection of the Botanical Institute, Russian Academy of Sciences)-has been studied. Culture of A. mellea was shown to be most sensitive to solutions of the model TC. It was demonstrated that the sensitivity of the luminous fungi is comparable with the sensitivity of the bacteria that are used for environmental monitoring. Use of the aerial mycelium of luminous fungi on the solid support as a test object is a promising approach in biotesting for the development of continuous biosensors for air monitoring.

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.

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.

    Biochemical changes causes lack of bioluminescence in fruiting bodies of Armillaria / A. P. Puzyr, S. E. Medvedeva, V. S. Bondar // Mycosphere. - 2017. - Vol. 8, Is. 1. - P9-17, DOI 10.5943/mycosphere/8/1/2 . - ISSN 2077-7000

Enzymes and substrate of luminescent reaction -- Kinetics of luminescence -- Luminous mycelia -- Nonluminous fruiting bodies of fungus
Аннотация: Mycelium of Armillaria species exhibit bioluminescence in nature and when cultivated on artificial nutrient media. However, fruiting bodies do not emit visible light. The present study investigates biochemical changes which cause this phenomenon. Light emission was studied in experiments with mixtures of cold and hot extracts of the luminous mycelium of Armillaria borealis IBSO 2328 and nonluminous fruiting bodies of this fungus and an unidentified species of the genus (Armillaria sp.). Hot extracts of fruiting bodies of the nonluminous Pholiota squarrosa were used as the substrate analog of the luminescent reaction, as previously this fungus had been found to contain a high amount of this substance. Control experiments showed that cold extracts of A. borealis IBSO 2328 mycelium contained enzymes for the luminescent reaction, which is initiated after addition hot extracts of P. squarrosa fruiting bodies. Parallel experiments with extracts of the fruiting bodies of Armillaria showed that: (i) - cold extracts did not contain enzymes of the luminescent reaction or contain very small amounts of these enzymes and (ii) - hot extracts did not contain substrate of the luminescent reaction. Thus, the reason why fruiting bodies of Armillaria do not emit light is that they do not contain components required for visible luminescence. The study discusses possible causes why the enzymes and substrate of the luminescent reaction are not synthesized in fruiting bodies of Armillaria. © Guizhou Academy of Agricultural Sciences.

    Why does the bioluminescent fungus Armillaria mellea have luminous mycelium but nonluminous fruiting body? / K. V. Purtov [et al.] // Doklad. Biochem. Biophys. - 2017. - Vol. 474, Is. 1. - P217-219, DOI 10.1134/S1607672917030176 . - ISSN 1607-6729
Аннотация: By determining the components involved in the bioluminescence process in luminous and nonluminous organs of the honey fungus Armillaria mellea, we have established causes of partial luminescence of this fungus. The complete set of enzymes and substrates required for bioluminescence is formed only in the mycelium and only under the conditions of free oxygen access. Since the synthesis of luciferin precursor (hispidin) and 3-hydroxyhispidin hydroxylase in the fruiting bodies is blocked, the formation of luciferin—the key component of fungal bioluminescent system—was not observed. That is why the fruiting body of Armillaria mellea is nonluminous despite the presence of luciferase, the enzyme that catalyzes the oxidation of luciferin with a photon emission. © 2017, Pleiades Publishing, Ltd.

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.

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.

Аннотация: Множество живых организмов, в т.ч. и грибов, обладают способностью к эмиссии видимого света. В настоящее время известно свыше 80 таксонов люминесцентных грибов, большинство из которых было обнаружено в тропиках. Среди светящихся грибов наиболее широко распространены виды рода Armillaria, которые являются деструкторами древесины, вызывающими корневую гниль. Они встречаются повсеместно в Северной Америке, Европе, Азии и Южной Африке. Из Коллекции культур базидиомицетов Ботанического института им. В.Л. Комарова РАН были отобраны штаммы A. mellea, A. gallica и Lampteromyces japonicus, обладающие люминесцентными свойствами. Было также показано, что способностью к свечению обладало большинство штаммов A. borealis, выделенных на территории Красноярского края. Табл.1. Библ. 25

Аннотация: С помощью определения компонентов-участников биолюминесцентного процесса в светящихся и несветящихся органах опёнка осеннего выяснили причины неполного свечения Armillaria mellea. Полный набор ферментов и субстратов, необходимых для биолюминесценции, образуется только в мицелии, причём исключительно в условиях свободного доступа кислорода. В плодовых телах синтез предшественника люциферина (гиспидина) и 3-гидроксигиспидингидроксилазы блокирован, вследствие этого и не происходило образование люциферина - ключевого компонента биолюминесцентной системы грибов. Именно поэтому плодовое тело опёнка осеннего не светится, несмотря на наличие люциферазы - фермента, катализирующего окисление люциферина с испусканием кванта света.

Аннотация: In in vitro experiments, the possibility of using a luminescent system extracted from the luminous fungus Armillaria borealis has been shown to detect and determine the concentration of hispidin. A linear dependence of the luminescent response on the content of hispidin in solutions in the concentration range of 5.4 x 10(-5) - 1.4 x 10(-2) mu M was detected. The stability of the enzyme system and the high sensitivity of the bioluminescent reaction allows carrying out multiple measurements with the analyte detection limit of 1.3 x 10(-11) g. The obtained results show the prospects of creating a rapid bioluminescent method for the analysis of medical substances or extracts from various biological objects for the presence of hispidin.

Аннотация: Modified nanodiamonds (MNDs) produced by detonation synthesis can be used as an effective adsorbent to immobilize extracellular peroxidases of the luminous basidiomycete Neonothopanus nambi. The enzymes are firmly immobilized on MND particles and exhibit catalytic activity. The indicator system (the MND-enzyme complex) reused many times retains its ability to catalyze reaction of co-oxidation of phenol and 4-aminoantipirine in the presence of hydrogen peroxide and remains functionally active during long-term storage (for 1 month or longer) in aqueous suspensions at 4 degrees C. MNDs and enzymes of higher fungi can be effectively used to construct new reusable indicator systems for analytical applications such as monitoring contamination of aquatic environments by phenolic compounds.

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: 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.
