Biolumniscencia con diferentes longitudes de honda

Se han conseguido aisalar proteinas rectificadas geneticamente para conseguir diferenetes tonalidades bioluminiscentes, creando una amplia y variada gama cormatica


En esta imagen podemos ver bacterias geneticamente modificadas con la proteina bioluminiscente en simbiosis con un alga microscopica. Al reporducirse heredan dicha proteina y de un pequeño cultivo nace toda una generacion de millones de ellas con las mismas propiedades. Algunas de estas bacterias se usan para crear fertilizantes ya que mejoran las caracteristacas de los sustratos, permitiendo un aprovechamiento mejor de los nutrientes


Pyrodinium bahamense dinoflagellates, tambien en las aguas oceanicas podemos encontrar estos seres.

Bluish flickers visible in ocean water at night often come from blooms of bioluminescent dinoflagellates, which emit short flashes of light when disturbed.

Red tides

The same red tide mentioned above is more specifically produced when dinoflagellates are able to reproduce rapidly and copiously on account of the abundant nutrients in the water. Although the resulting red waves are a miraculous sight, they, again, contain toxins that not only affect all marine life in the ocean but the people who consume them as well. A specific carrier is shellfish. This can introduce both non-fatal and fatal illnesses. One such poison is saxitoxin, a powerful paralytic. Human inputs of phosphate further encourage these red tides, and consequently there is a strong interest in learning more about dinoflagellates, from both medical and economic perspectives.
