Regulation of Bioluminescence in Photobacterium leiognathi Strain KNH6.

UNLABELLED Bacterial bioluminescence is taxonomically restricted to certain proteobacteria, many of which belong to the Vibrionaceae. In the most well-studied cases, pheromone signaling plays a key role in regulation of light production. However, previous reports have indicated that certain Photobacterium strains do not use this regulatory method for controlling luminescence. In this study, we ...

Complete Genome Sequence of Photobacterium leiognathi Strain JS01

Photobacterium leiognathi is a bioluminescent symbiont of fish of the Leiognathidae family. Here, we present the full-genome sequence of P. leiognathi strain JS01, a strain isolated from a nonluminescent Loligo sp. squid of Singaporean origin. No finished genome sequence of this species is currently publicly available.

Determination of pyruvic acid concentration using a bioluminescence system from Photobacterium leiognathi.

A novel, highly sensitive and selective bacterial luminescence method for the detection of pyruvic acid (PA) is reported here. This method is based on a reaction system catalyzed by lactate dehydrogenase (LDH) with the bacterial luciferase-FMN:NADH oxidoreductase bioluminescence system in vitro. The reduced nicotinamide adenine dinucleotide (NADH) involved in the LDH reaction system could be qu...

The stimulation of bioluminescence in Photobacterium leiognathi as a potential prescreen for antitumor agents.

The stimulation of bioluminescence in Photobacterium leiognathi has previously been described as a test for genotoxic compounds. An adaptation of this procedure has been developed which uses a dim variant of P. leiognathi and permits the prescreening of microbial fermentation broths for potential antitumor agents. Bioluminescence in this organism was stimulated by compounds which bind to DNA or...

Genomic polymorphism in symbiotic populations of Photobacterium leiognathi.

Photobacterium leiognathi forms a bioluminescent symbiosis with leiognathid fishes, colonizing the internal light organ of the fish and providing its host with light used in bioluminescence displays. Strains symbiotic with different species of the fish exhibit substantial phenotypic differences in symbiosis and in culture, including differences in 2-D PAGE protein patterns and profiles of indig...
