Free Radical Participation in Bacterial Bioluminescence
Free Radical Research Communications, 1986The metastable intermediate II produced on reaction of bacterial luciferase with reduced flavin mononucleotide and O2, reacts with any of several stable free radicals to produce bioluminescence. The bioluminescence spectrum is very similar to that from the well-studied intermediate II and aldehyde reaction, and the number of photons per luciferase ...

Inhibition of bacterial bioluminescence by pargyline
Archives of Biochemistry and Biophysics, 1979Abstract Pargyline ( N -benzyl- N -methyl-2-propynylamine), an inactivator of mitochondrial monoamine oxidase, inhibits growth and in vivo and in vitro bioluminescence in Beneckea harveyi . The inhibition is competitive with the two substrates, FMNH 2 and aldehyde, and the inhibitor binds with a reaction intermediate of the the enzyme ...

Bacterial bioluminescence assay for bioanalysis and bioimaging
Analytical and Bioanalytical Chemistry, 2021Bioluminescence occurs through a chemical reaction in organisms that spontaneously produce light. Luminescent bacteria are unique among bioluminescent organisms. Their bioluminescence intensity is an indicator of their metabolic activity, which can directly reflect the influence of environmental factors on cell viability.

Bacterial Bioluminescence, Bioelectromagnetics and Function
Photochemistry and Photobiology, 2010AbstractThe biological functions of light emission in bacterial bioluminescence are not always obvious, especially if the bacteria are in a free‐living mode. Experimental evidence suggests that light emission confers benefit to the bacteria themselves such as through photoreactivation and involves as much as 20% of cell energy metabolism. A theoretical

Bacterial bioluminescence inhibition by Chlorophenols
Applied Biochemistry and Microbiology, 2000Photobacteria were used as a test object for rapid monitoring of ecotoxicants. Specific inhibitory effects of phenol and its chlorinated derivatives (2-chlorophenol, 2,3-dichlorophenol, pentachlorophenol, 2,4-dichlorophenoxyacetic acid, and 2,4,5-trichlorophenoxyacetic acid) on bioluminescence and respiration of intact cells, as well as on the emission

In Vivo Bacterial Imaging Using Bioluminescence
2018Bacterial luminescence allows for noninvasive continuous monitoring of promoter activity in a wide range of model systems. This chapter details various examples of use of the lux reporter system to measure promoter activity in bacteria using the vector pUC18T-mini-Tn7T-lux-Tp.

Model reactions for bacterial bioluminescence
Journal of the Chemical Society, Chemical Communications, 1976Acid-catalysed addition of hydrogen peroxide to n-butyl vinyl ether gave a separable mixture of the hydroperoxides (1)–(4); peroxides (1)–(3) undergo chemiluminescent reactions in acetonitrile with 1,3,10-trimethylisoalloxazinium perchlorate in the presence of triethylamine, and the flavin analogue catalyses the decomposition of the peroxides.

An efficient bacterial bioluminescence with reduced lumichrome
Biochemical and Biophysical Research Communications, 1981Summary Photoreduced lumichrome reacts in vitro with oxygen in the presence of tetradecanal and a specially purified sample of bacterial luciferase selected for minimum fluorescence at 490 nm upon 350 nm excitation from Vibrio harveyi yielding a rapidly decaying bioluminescence with an emission maximum at 476 nm.

The inhibition of bacterial bioluminescence by xenobiotics
Xenobiotica, 1985The effect of various xenobiotic substrates of microsomal cytochrome P-450, including dimethylaniline, ethylmorphine, hexabarbital and aminopyrine, on the bioluminescence of the bacteria Vibrio fischeri and the bacterial luciferase mixed-function oxidase system is described. These compounds are effective inhibitors of the luminescence reaction.
