Bacterial luciferase as a reporter of circadian gene expression in cyanobacteria.
To allow continuous monitoring of the circadian clock in cyanobacteria, we previously created a reporter strain (AMC149) of Synechococcus sp. strain PCC 7942 in which the promoter of the psbAI gene was fused to Vibrio harveyi luciferase structural genes (luxAB) and integrated into the chromosome. Northern (RNA) hybridization and immunoblot analyses were performed to examine changes in abundance...
متن کاملIsolation, identification and characterization of new luminous bacteria from Chah Bahar Port, southern marine habitat of Iran
Coastal region of Chah Bahar port, Sea of Oman, was screened for the presence of bioluminescence bacteria for the first time. Water samples were taken from surface and subsurface layers and immediately spread on nutrient seawater complete (SWC) agar. Luminous colonies were observed after an overnight incubation at 25°C. Among twenty luminous isolates, four of them were selected for preliminary ...
متن کاملRapid Diagnosis of Bacteriuria by Measuring Bacterial Adenosine Triphosphate Using a Bioluminescence Assay
A rapid method for quantifying bacteriuria was evaluated in 114 clinical specimens using a bacterial adenosine triphosphate (ATP) assay. The procedure allows for removal and destruction of non-bacterial ATP and subsequent analysis of bacteria ATP by firefly (Photinus pyralis) luciferin -luciferase bioluminescence and requires 30 minutes as a whole. The correlation coefficient between the number...
متن کاملStrongly enhanced bacterial bioluminescence with the ilux operon for single-cell imaging
Bioluminescence imaging of single cells is often complicated by the requirement of exogenous luciferins that can be poorly cell-permeable or produce high background signal. Bacterial bioluminescence is unique in that it uses reduced flavin mononucleotide as a luciferin, which is abundant in all cells, making this system purely genetically encodable by the lux operon. Unfortunately, the use of b...
متن کاملNatural selection on the luxA gene of bioluminescent bacteria
Despite a growing literature of Vibrio, Photobacterium, Shewanella, and Photorhabdus biology, little is known of the function bioluminescence provides to these light-emitting bacteria. Proposed benefits of bioluminescence include evasion of predators or attraction of prey for symbiotic bacterial hosts through a distraction, a method of oxygen consumption to suffocate a host or reduce competitio...
