Bioluminescent fungi emit a greenish light with a maximum intensity at 520-530 nm. Some luminescent fungi, for example A. mellea, reportedly exhibit diurnal periodicity and seasonal variation of bioluminescence.
Luminescence may occur in both mycelia and fruiting bodies, as for example in P. stipticus and O. olearius, or only in mycelia. Fungal luminescence has been shown to require oxygen and in vitro light output has been characterised as an NAD(P)H-dependent luciferin-luciferase system for A. mellea and M. Citricolor but not for P. Stipticus.
The role of luminescence is to attract invertebrates to assist fungal spore dispersal. Bioluminescence is a by-product of a biochemical reaction and has no ecological value.
Применение Many scientific researchers have incorporated luminescent mushroom into applications in testing for pollutants in water supply when concentrations are too low to detect by conventional means. Fungi are of special interest because like us, they are eucaryotes and our metabolism is more related to theirs than to that of the procaryotic bacteria. The metabolite from luminescent mushroom present the effectively bioactive in anti-mould, anti-bacteria, anti-virus and especially in inhibiting growth of cancer cell.
