Statistical Optimization of Bioluminescence of Photobacterium posphoreum KCTC2852.

Journal of Bioscience and Bioengineering, 2001
In this study, media optimization by statistically designed experiments stimulated an increase in the intensity and stability of bioluminescence of Photobacterium phosphoreum KCTC 2852 during continuous cultivation. The Plackett-Burman design method selected two components (NaCl, yeast extract) among nine components of the seawater complete (SC) medium.

Properties of the Bimodal Fluorescent Protein Produced by Photobacterium phosphoreum

Photochemistry and Photobiology, 2000
A fluorescent protein isolated from the deep-sea luminous bacterium Photobacterium phosphoreum strain bmFP has been purified, cloned and sequenced. The protein is 96.5% identical in amino acid sequence to FP390, the weakly fluorescent flavoprotein encoded by the luxF gene characteristic of Photobacterium species.

Interspecies toxicity correlations of rat, mouse and Photobacterium phosphoreum

Environmental Toxicology and Chemistry, 1994
Abstract This study investigates quantitatively the interspecies relationships of the acute toxicity of 684 organic chemicals to the rat, the mouse, and the luminescent marine bacterium Photobacterium phosphoreum, commonly known as the Microtox® test The results indicate significant relationships between the Microtox EC50 and rat and ...

Chemical characterization of lumazine protein from Photobacterium leiognathi: comparison with lumazine protein from Photobacterium phosphoreum

Biochemistry, 1985
The properties of lumazine proteins purified from the marine bioluminescent bacteria Photobacterium phosphoreum, a psychrophile, and Photobacterium leiognathi, a relatively thermophilic species, are compared. An accurate 1:1 stoichiometry of binding of the ligand 6,7-dimethyl-8-ribityllumazine to each lumazine protein is established by back-titration ...

Differential sensitivity to mutagens by Photobacterium phosphoreum

Journal of Microbiological Methods, 1985
Abstract The in vivo luminescence responses to eight different mutagenic chemicals were assessed in Photobacterium phosphoreum . The mutagenic effects of these compounds were determined with an N -methyl- N ′-nitro- N -nitrosoguanidine (MNNG) induced dark mutant.

[14] Fatty acid reductase from Photobacterium phosphoreum

1986
Publisher Summary This chapter discusses the fatty acid reductase from Photobacterium phosphoreum. Fatty acid reductases from bioluminescent bacteria are responsible for the synthesis of long-chain aldehydes used as substrates in the luciferase-catalyzed luminescent reaction. Both ATP and NADPH are required for the reduction of fatty acids.

МЕТОДИКА ПРОВЕДЕННЯ МОНІТОРИНГУ ЗМІН ІНТЕНСИВНОСТІ ЛЮМІНЕСЦЕНЦІЇ PHOTOBACTERIUM PHOSPHOREUM

Біотехнологія XXI століття, 2023
Існує багато праць, що варіації геомагнітного поля мають високу ступінь подібності з динамікою змін багатьох мікробіологічних та клітинних систем та процесів, особливо під час магнітних бур [1]. Використання мікробіологічних біосенсорів за моніторингу геомагнітної активності дає змогу дослідити різні біологічні ефекти під час варіацій геомагнітного ...

ATP pool and bioluminescence in psychrophilic bacteria Photobacterium phosphoreum

Microbiology, 2014
Bioluminescence activity and ATP pool were investigated in the cells of psychrophilic bacteria Photobacterium phosphoreum collected from the exponential and stationary growth phases and immobilized in polyvinyl alcohol (PVA) cryogel. In liquid culture, ATP pool remained at an almost constant level throughout the luminescence cycle (over 100 h). The ATP

Bioluminescence and cell growth of Photobacterium phosphoreum.

Journal of biochemistry, 1980
The bioluminescence activity of Photobacterium phosphoreum was compared at different times after cell division by the methods of density gradient centrifugation and synchronous culture. The bioluminescence intensity per cell mass increased linearly at a rate of 1.5 times per doubling time.

Evaluation and Structure-Activity Relationship Study of Acute Toxicity of Naphthoquinones to Photobacterium phosphoreum, Photobacterium T3B

Bulletin of Environmental Contamination and Toxicology, 2010
The acute toxicities of five naphthoquinone compounds to Photobacterium phosphoreum were determined. We evaluated the mechanism of toxicity using the structure-activity relationship technique. The results showed that some factors, including the species of substituents, shape/size of molecule and oil-water partition coefficient (log P) played the ...
