I’m Catie Wayne.
And this is ‘Animalist News.’
We humans have been using yeast to make bread, beer, and wine
for over 5,000 years.
And many humans would agree that alcohol and beer in particular
Yeast, a bunch of microorganisms in the fungi family,
is fundamental in the brewing process.
It creates the alcohol and carbon dioxide,
which makes beer bubbly, obvi.
But the rule of yeast is a little more complicated
Yeast cells also produce aroma compounds
that are essential for the flavor and taste of the beer.
But one might wonder why yeast cells produce these aroma
compounds that make beer so delightful.
I mean, it certainly isn’t so bearded men everywhere
can make that satisfactory ah noise
after taking a swig of their favorite beer.
That is some sweet aroma compounds.
Well, according to a recent study
by VIB, the Flanders Institute for Biotechnology,
these aroma compounds appear to have evolved specifically
to attract fruit flies– much in the same way flowers
attract bees– so that these yeast cells can hitch
a ride on the flies and spread their genetic material
In other words, it would appear that we
have fruit flies to thank for the taste of beer.
So, I tip my fedora to you, flies.
Does this make you suddenly love fruit flies?
