Structural identification of autoinducer of Photobacterium fischeri luciferase

Biochemistry, 1981
Synthesis of bacterial luciferase in some strains of luminous bacteria requires a threshold concentration of an autoinducer synthesized by the bacteria and excreted into the medium. Autoinducer excreted by Photobacterium fischeri strain MJ-1 was isolated from the cell-free medium by extraction with ethyl acetate, evaporation of solvent, workup with ...

Induction of Superoxide Dismutases inPhotobacterium Leiognathi

Free Radical Research Communications, 1991
We investigated the induction of Cu,Zn-SOD (bacteriocuprein) and Fe-SOD in Photobacterium leiognathi DK-A1 which was isolated from the light organ of the squid, Droteuthis kensaki. The induction of superoxide dismutases depended on the addition of paraquat to the medium.

The terminal oxidase of Photobacterium phosphoreum. A novel cytochrome

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1979
The terminal oxidase of Photobacterium phosphoreum has been purified to the electrophoretically homogeneous state and some of its properties have been studied. The enzyme catalyses oxidation of ascorbate in the presence of phenazine methosulphate or N,N,N',N'-tetramethyl-p-phenylenediamine. The reaction is inhibited by cyanide. Nitrite at comparatively

Synergistic Effects of Four Heavy Metals on Photobacterium

Advanced Materials Research, 2013
The synergistic effects of mixtures of CdCl2, Ni (NO3)2, CuSO4, and ZnSO4 on photobacterium Q67 were predicted and evaluated by using models of concentration addition (CA), independent action (IA), effect summation (ES), ES with the exponent e (ESE), ES with the power of the number of components n (ESN), and integrated CA with IA based on multiple ...

Electrotransformation of Photobacterium damselae subsp. piscicida

2000
Photobacterium damselae subsp. piscicida (formerly Pasteurella piscicida) is a marine pathogenic bacterium associated with severe epizootics in cultivated and wild fish. Attempts to transform it using standard electroporation protocols (Dover et al., 1988; Cutrin et al., 1994) were not successful.

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.

Control of in vivo luminescence in psychrophilic marine photobacterium

Archiv f�r Mikrobiologie, 1973
1. The control of luminescence in a psychrophilic marine Photobacterium is different from that previously reported in other photobacteria. 2. Synthesis of the luminescent system can be inhibited by glucose and by components in tryptone or peptone; this type of inhibition was not reversible by addition of c-AMP. 3.
