Bioluminescence arises human interest for centuries. Occurring in four of seven taxonomical Kingdoms, Monera, Chromista, Animalia and Fungi, each of them with completely different mechanisms. The chemical study of bioluminescence starts in XIX century with Dubois, who coined the terms luciferin and luciferase, generic terms for substrate and enzyme involved in the bioluminescent reaction, respectively.

In the specific case of fungi, enzyme involvement has been debated for almost five decades, after the enzymatic proposal by Airth and Foerster, during the decade, and the non-enzymatic proposal by Shimomura in It was only in when the proposal by Airth and Foerster was confirmed by our group, followed by the identification of the fungal luciferin and the involvement of hispidin, as the precursor molecule, in by Yampolskys group.

To elucidate the chemical mechanisms, mass spectrometry can be employed to structural identification of reagents and intermediates on these and other organic reactions.

After the confirmation of hispidin involvement in fungi bioluminescence, liquid chromatography coupled with mass spectrometry was uses do identify the presence of hispidin, its derivatives and precursor intermediates in fungi and selected plants.

Although it was described by Aristotle, the emission of light by bioluminescent mushrooms remained a mystery for thousands of years. Since , however, the mystery began to be unraveled, with the publication of articles on the ecological function of light emission, the identity of luciferin, luciferase and the mechanism of light emission. With the collaboration of groups in Russia, USA and Japan, our group actively participated in the elucidation of this system. Similar to the bioluminescence of fireflies, whose study allowed the development of several analytical tools for the most diverse purposes, from rapid bioassays for monitoring microbial contamination of food to the use of luc and lux genes as a probe in Molecular Biology, the study of bioluminescent fungi have the potential to generate new academic and applied knowledge. Stevani's Lab. PPS Evidence that a single bioluminescent system is shared by all known bioluminescent fungal lineages.
