Abstract Keroplatus is a genus of fungus gnats family Keroplatidae (Diptera, Bibionomorpha). Larvae some species emit constant blue light from the body. The bioluminescence one least studied all terrestrial insects and very few facts are known to date its biology biochemistry. Here we report high level riboflavin in testaceus larvae, fluorescent compound that might be relative bioluminescent sy...

The Hazard Analysis and Critical Control Points (HACCP) system prevents manages physical, chemical biological risks at places where foods beverages are processed, packaged, distributed consumed. present study (1) assessed the level of microbial contamination food contact surfaces using adenosine triphosphate (ATP)-bioluminescence in Iraq restaurants; (2) investigated surfaces; (3) evaluated eff...

pyruvate kinase is a key enzyme in glycolytic pathway that catalyzes the transphosphorylation between phosphoenolpyruvate and adp to yield atp and pyruvate. geobacillus stearothermophillus has a stable pyruvate kinase with determined crystal structure that composed of four separate domains. given that limited proteolysis experiments can be successfully used to probe conformational features of p...

Kahle and Umbers introduce the ways by which organisms emit light though chemical reactions.

Bioluminescence is a two-person improvised performance to be considered for either concert or club performance. The performance is improvised and of variable length, and consists of a vocalist (Lesley Flanigan) and a laptop performer (R. Luke DuBois). All the material generated from the laptop is taken from the vocalist during that performance (no pre-sampling or synthesis) and the laptop perfo...

A reconstruction method of bioluminescence sources is proposed based on a phase approximation model. Compared with the diffuse approximation, this phase approximation model more correctly predicts bioluminescence photon propagation in biological tissues, so that bioluminescence tomography can accurately locate and quantify the distribution of bioluminescence sources. The compressive sensing (CS...

Bioluminescence from cells is so dim that bioluminescence microscopy is performed using an ultra low-light imaging camera. Although the image sensor of such cameras has been greatly improved over time, such improvements have not been made commercially available for microscopes until now. Here, we customized the optical system of a microscope for bioluminescence imaging. As a result, bioluminesc...

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 ...
