Natural Occurrence
Ethanol is a byproduct of the metabolic process of yeast. As such, ethanol will be present in any yeast habitat. Ethanol can commonly be found in overripe fruit. Ethanol produced by symbiotic yeast can be found in Bertam Palm blossoms. Although some species such as the Pentailed Treeshrew exhibit ethanol seeking behaviors, most show no interest or avoidance of food sources containing ethanol. Ethanol is also produced during the germination of many plants as a result of natural anerobiosis. Ethanol has been detected in outer space, forming an icy coating around dust grains in interstellar clouds.

Famous quotes containing the words natural and/or occurrence:
“Any woman who chooses to behave like a full human being should be warned that the armies of the status quo will treat her as something of a dirty joke. That’s their natural and first weapon. She will need her sisterhood.”
—Gloria Steinem (b. 1934)
“One is absolutely sickened, not by the crimes that the wicked have committed, but by the punishments that the good have inflicted; and a community is infinitely more brutalised by the habitual employment of punishment than it is by the occasional occurrence of crime.”
—Oscar Wilde (1854–1900)
