In the purified bacterial bioluminescent system obtained from Photobacterium jischeri it has been shown that the first step involves the reduction of enzyme by reduced flavin mononucleotide, followed by a combination of reduced enzyme with molecular oxygen (I). The proposed reaction scheme illustrates that aldehyde (RCHO) then reacts with a hypothetical peroxide intermediate to form a complex w...

We report here the whole draft genome sequence of marine isolate Photobacterium halotolerans S2753, which produces the known antibiotic holomycin and also ngercheumicins and solonamides A and B, which interfere with virulence of methicillin-resistant Staphylococcus aureus strains by interacting with the quorum-sensing system.

Broomcorn millet Huangjiu brewing is usually divided into primary fermentation and post-fermentation. Microbial succession the major factor influencing development of typical flavor. Here, we report changes in flavor substances microbial community during broomcorn Huangjiu. Results indicated that a total 161 volatile compounds were measured fermentation, estragole was detected for first time A ...

The molecular mechanism(s) by which deep-sea bacteria grow optimally under high hydrostatic pressure at low temperatures is poorly understood. To gain further insight into the mechanism(s), a previous study screened transposon mutant libraries of the deep-sea bacterium Photobacterium profundum SS9 and identified mutants which exhibited alterations in growth at high pressure relative to that of ...

Photobacterium damselae subsp. piscicida is a causative bacterium of fish pasteurellosis, which has caused serious economic damage to aquaculture farms worldwide. Here, the whole-genome sequence of P. damselae subsp. piscicida 91-197, isolated in the United States, suggests that this genome consists of two chromosomes and two plasmids.

An N-terminal and C-terminal truncated recombinant α2-6-sialyltransferase cloned from Photobacterium sp. JH-ISH-224, Psp2,6ST(15-501)-His(6), was shown to be an efficient catalyst for one-pot three-enzyme synthesis of sialyl Tn (STn) antigens and derivatives containing natural and non-natural sialic acid forms.

Here, we present the whole-genome sequence of Photobacterium halotolerans strain, MELD1, isolated from the roots of a terrestrial plant Phragmites australis grown in soil heavily contaminated with mercury and dioxin. The genome provides further insight into the adaptation of bacteria to the toxic environment from where it was isolated.

Substantial ambiguity exists regarding the phylogenetic status of facultatively psychrophilic luminous bacteria identified as Photobacterium phosphoreum, a species thought to be widely distributed in the world's oceans and believed to be the specific bioluminescent light-organ symbiont of several deep-sea fishes. Members of the P. phosphoreum species group include luminous and non-luminous stra...

conclusions the obtained results revealed that there has been a high rate of genetic diversity in bioluminescent strains isolated from gulf of izmir and v. lentus and v. crassostreae strains could be also bioluminescent for the first report. at the same time, pfge analysis of bioluminescent bacteria including four different genera and ten different species were shown for the first time by this ...
