The University of Sevilla has patented a method for culturing the bacteria Vibrio fischeri and the algae Pyrocystus fusiformis in order to configure bioluminescent devices that emit light without electricity consumption, with applications in environmental lighting and signaling.
Bioluminescence is a widespread phenomenon at all biological levels (bacteria, fungi, worms, insects, etc.). It consists of light emission that certain living organisms are able to generate, usually through photoluminescence or chemiluminescence. Using the bacteria Vibrio fischeri and bioluminescent micro-algae Pyrocystis fusiformis, it is possible to obtain ambient lighting devices, which emit light without power consumption and without damaging the environment.
The main novelty of this patent lays in the method of obtaining ambient lighting devices, taking advantage of the luminous features presented by the microorganisms of the project with the aim of producing natural light without consuming electricity and without emitting harmful waste to the environment. These two qualities are great advantages compared to traditional lighting systems. Furthermore, this invention presents geometric design built up with biodegradable and/or recycled materials,
