Светящиеся грибы

• 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.
