Resumen
[ES] La bioluminiscencia consiste en la emisión de luz por organismos vivos. Se debe una reacción química y ha estado en constante evolución, generándose diversas especies con esta capacidad. Las bacterias son las más abundantes, ya sea en forma de vida libre o en simbiosis, como es el caso de Aliivibrio fischeri que destaca no sólo por su mutualismo con el calamar (Euprymna scolopes) sino también porque permitió definir el proceso de comunicación celular conocido como “quorum sensing”. Su importancia actual radica en las ventajas que aportan estas bacterias a los organismos hospedadores sobre sus depredadores, así como en su posible utilización tecnológica de crear una iluminación natural y ambiental. Con este trabajo se estudiará como de frecuente es la presencia y abundancia de las bacterias luminiscentes en los alimentos que ingerimos, según la época del año y la temperatura del mar, así como se obtendrá más información de interés sobre ellas.

Bacteria are the most abundant, either as free-living or in symbiosis, as is the case of Aliivibrio fischeri that stands out not only for its mutualism with the squid (Euprymna scolopes) but also because it allowed us to define the cellular communication process known as “quorum sensing”. Its current importance lies in the advantages that these bacteria provide to the host organisms over their predators, as well as in their possible technological use to create natural and environmental lighting. With this work we will study the presence and abundance of luminescent bacteria in the food we eat, how this depends on the time of year and the temperature of the sea, as well as more interesting information about them.
