A conflict: Induction-inhibition of luminescence in the expression of lux-genes in transgenic bacteria [Текст] / D. V. Lesnyak, L. Y. Popova // Biofizika. - 2002. - Vol. 47, Is. 6. - P. 1059-1063. - Cited References: 12 . - ISSN 0006-3029

salicylate, naphtalene concentration -- bacterial bioluminescence, biodegradation
Аннотация: The relationship between the induction of the luminescent operon of lux-genes fused with the naphthalene and salicylate degradation genes and the inhibition of light emission caused by these compounds was studied. The quantitative correlations between these processes manifest themselves in the fact that light intensity linearly increased in a narrow concentration range of the inductor and then decreased due to the inhibition of the luminescence reaction itself, which is not related to the regulation of expression of lux-genes.

Аннотация: Upcoming professional sports authorities seek rapid noninvasive biosensing tools for regular monitoring of athletes' physiological states. The analysis of saliva through luminescence-based biosensors has been perceived as a suitable candidate for such purposes. The present study reports a qualitative bioluminescence assay based on a coupled enzyme system that consists of bacterial luciferase (BLuc) and nicotinamide adenine dinucleotide (NADH):flavin mononucleotide (FMN) oxidoreductase (Red), BLuc-Red, for the express diagnostics of athletes' stress levels before and after physical exertion. The volunteers who participated in the study were grouped as freestyle wrestlers and students who adapted to different levels of physical activities. Under physical exertion modelling conditions, the influence of participant saliva on BLuc-Red catalyzed light emission was investigated. Results showed a significant increase in residual luminescence (I-exp, mean maximum bioluminescence intensity of the experimental measurement (I-exp); I-c, luminescence intensity in control; I-exp/I-c, %) values for participants in the wrestler group while a decrease in the student group (P < 0.05). Such contrasting residual luminescence values in both groups were found to be dependent on the catalase activity of saliva. The proposed bioluminescence assay can be utilized as a potential nonspecific biosensing tool for determining the physical state of athletes under high loads.

Аннотация: The Ca2+-regulated photoprotein obelin determines the luminescence of the marine hydroid Obelia longissima. Bioluminescence is initiated by calcium and appears as a result of the oxidative decarboxylation related to the coelenterazine substrate. The luciferase of the luminescent marine coral Renilla muelleri (RM) also uses coelenterazine as a substrate. However, three proteins are involved in the in vivo bioluminescence of these animals: luciferase, green fluorescent protein, and Ca2+-regulated coelenterazine-binding protein (CBP). In fact, CBP that contains one strongly bound coelenterazine molecule is the RM luciferase substrate in the in vivo bioluminescent reaction. Coelenterazine becomes available for oxygen and the reaction with luciferase only after binding CBP with calcium ions. Unlike Ca2+-regulated photoproteins, the coelenterazine molecule is not activated by oxygen in the CBP molecule. In this work, by means of quantum chemical methods the behavior of substrates in these proteins is analyzed. It is shown that coelenterazine can form different tautomers: CLZ(2H) and CLZ(7H). The formation of 2-hydroperoxy-coelenterazine is studied. According to the obtained data, these proteins use different forms of the substrates for the reaction. In obelin, the substrate is in the CLZ(2H) form that affords hydrogen peroxide. In RM, coelenterazine is in the CLZ(7H) form, and therefore, CBP is not activated by oxygen.

Аннотация: The bacterial bioluminescence has high sensitivity to the action of various inhibitors of biological activity. The lyophilized luminous bacteria Photobacterium phosphoreum (Microbiosensor B17 677F) and luminous strain Escherichia coli (Microbiosensor EC) from the Culture Collection IBSO were used to create bioluminescent biotests. They have been applied in ecological monitoring to determine the overall toxicity of the Yenisei and Angara Rivers and some water sources of Altai Territory. As a rule the heaviest pollution of water in studied rivers was registered near cities and settlements. The luminous bacteria biotests are simple and convenient in work, standardized and quantitative, have rapid response to actions of different substances and high sensitivity to environmental pollutants. It takes less than 30 min to do the biotest (the other biotests take 48-96 h). Copyright В© 1999 John Wiley & Sons, Ltd.

Аннотация: Modern physical training systems give a high priority to the training process individualizing elements that may be efficient enough only when supported by objective tests to rate the bodily responses to physical workloads. Moreover, success in modern professional sports is impossible unless supported by the newest medical/ biological findings and technologies in the health rating and forecast domains, with a special role played by the modern biophysical research of the cellular- and molecular-level biological processes. The study was designed to assess benefits of biophysical analysis of saliva for the athletic functionality rating tests. Sampled for the purposes of the study were athletes of different skill levels (from Class I to Honorary Masters of Sport) versus the untrained students, with the saliva sampled prior to and after physical trainings by bioluminescence and chemoluminescence test methods. The test data were processed by Statistica 10 (made by StatSoft Inc., the US) toolkit to produce median values (Me) and inter-quartile distribution (C25-C75 percentile) rates. The Mann-Whitney nonparametric U-test of the null hypothesis was used to rate differences of the independent variables, with the statistical difference rated meaningful at p<0.05. The bioluminescence tests found the higher ferment activity of saliva in the athletes’ versus untrained students, with the ferment activity in the bioluminescence tests also tested to grow after physical workloads in the highly-skilled athletes and fall in the untrained students. The study found the saliva antioxidant system functional intensity being athletic skills dependent. Therefore, the study has demonstrated benefits of the biophysical (bioluminescence and chemoluminescence) tests of saliva for the athletic functionality rating tests in the physical workload design and management initiatives. © 2019, Teoriya i praktika fizicheskoy kul'tury i sporta.

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

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.

Аннотация: The Institute of Biophysics SB RAS hosts and maintains a specialized collection of luminous bacteria (CCIBSO 836) containing over 700 strains isolated in various regions of the world's oceans. The culture collection is a source of lux genes and biologically active substances. The wide application of bioluminescence in medicine and ecology has given importance to analys-ing information on the structure and functioning of bioluminescence systems in natural and transgenic microorganisms, as well as on their features that are closely interrelated with bioluminescence. The aims of our BIOLUMBASE database are: gathering information on microorganisms with lux genes, their analysis and free access, and distribution of this data throughout the global network. The database includes two sections, natural and transgenic luminous microorganisms, and is updated by our own experimental results, the published literature and internet resources. For the future, a publicly available internet site for BIOLUMBASE is planned. This will list the strains and provide comprehensive information on the properties and functions of luminous bacteria, the mechanisms of regulation of bioluminescence systems, constructs with lux genes, and applications of bioluminescence in microbiology, ecology, medicine and biotechnology. It is noteworthy that this database will also be useful for evaluation of biological hazards of transgenic strains. Users will be able to carry out bibliographic and strain searches starting from any feature of interest. Copyright В© 2005 John Wiley & Sons, Ltd.

Аннотация: For analytical purposes bioluminescence can be used in three main ways: 1. luminescence measurement of bioluminescent system components isolated in vitro; 2. determination of luminous organisms' reaction to the in vivo test-action; 3. measurement of bioluminescence in marine ecological systems. The majority of the reports of this Symposium are dealing with the first two topics. The aim of our presentation is to draw attention to the third one. The possibilities of bioluminescent analysis are wider than its traditional scheme of applications in the laboratory, when the emitting system is withdrawn from a native source and is placed in a cuvette of the light measuring device. The reverse scheme is also possible, i.e. the device can be introduced into light emitting system such as a marine biocenosis--the community of the sea inhabitants--where we obtain a highly sensitive and rapid means of gaining the information on the vital activity of marine ecosystems, i.e. their spatial structure, rhythms, man's influence upon them, etc. The present communication will consider the possibilities of this form of bioluminescent analysis.

Аннотация: New results obtained in the detection of rhythms in the low frequency range in the light signal of a small number of photo bacteria are reported. The luminescence of a small number of bacteria was recorded with an apparatus the sensitivity of which was 12 quanta/pulse. To check the possible rhythms in the luminescence of the bacteria, correlation analysis was made of the interpulse intervals of the detection of the signal with a computer. This revealed a definite rhythm in the bacterial luminescence the fundamental frequency of which lies in the region 8 c/s. Profound modulation of a bioluminescent signal at this and multiple frequencies was demonstrated. The harmonic components found in the spectrum of the signal refute the existing view of the continuous character of bacterial luminescence.
