The use of bioluminescent biotests for study of natural and laboratory aquatic ecosystems / V. A. Kratasyuk [et al.] // Chemosphere. - 2001. - Vol. 42, Is. 8. - P909-915, DOI 10.1016/S0045-6535(00)00177-6 . - ISSN 0045-6535

Аннотация: A set of bioluminescent tests was developed to monitor water quality in natural and laboratory ecosystems. It consisted of four bioluminescent systems: luminous bacteria, coupled enzyme system NADH:FMN-oxidoreductase-luciferase and triplet enzyme systems with alcohol dehydrogenase and trypsin. The set of biotests was applied for a small forest pond (Siberia, Russia), laboratory microecosystems polluted with benzoquinone and a batch culture of blue-green algae. Thereby effects of natural water compared to those of models of heavy pollution and "bloom" of blue-greens on the bioluminescent tests were revealed. The set of biotests was not affected by a natural seasonal variability of water quality in the unpolluted pond, but responded to the heavy pollution and the "bloom" of blue-greens. The set of biotests could be recommended as the alarm test to control the acute toxicity of natural water bodies. В© 2001 Elsevier Science Ltd.

Bioluminescent method in studying the complex effect of sewage components / D. I. Stom [et al.] // Archives of Environmental Contamination and Toxicology. - 1992. - Vol. 22, Is. 2. - P203-208 . - ISSN 0090-4341

Аннотация: The inhibition of bacterial luminescence has been used in testing industrial enterprises sewage. The toxicity of the sewage is less than the total toxicity of separate components due to neutralization of quinone products of polyphenol oxidation in the reactions with the other phenol components of sewage. Toxicity increase is due to their influence on the cell membrane. Studies of cell ultrastructure confirm this fact. The studied mechanism of the complex effect allowed a more accurate forecast of the ecological situation during the discharge of phenol compounds and metals. It also showed the necessity of taking into account the complex effect of sewage components on contaminant discharge into water reservoirs.
