Does beer contain ethanol alcohol?

Beer does contain ethyl alcohol (ethanol). Beer is made from water, barley, hops, and yeast. The water and barley are mashed to produce sugars that the yeast metabolizes to produce ethanol. Beer yeast can produce alcohol levels from 2.5-18% alcohol by volume.

Who is the Father of American microbiology for inventing the fermentation tube?

French chemist Louis Pasteur was the first known zymologist, when in 1856 he connected yeast to fermentation. Pasteur originally defined fermentation as "respiration without air". Pasteur performed careful research and concluded "I am of the opinion that alcoholic fermentation never occurs without simultaneous organization, development and multiplication of cells.... If asked, in what consists the chemical act whereby the sugar is decomposed ... I am completely ignorant of it."


What is made from ethanol?

Anaerobic digestion of SIMPLE SUGARS by yeast like organisms - it is a metabolic byproduct. This is called fermentation. There are also iindustrial methods, some of which employ basically the same process on much larger scales. In practice, however, much ethanol is made from petroleum via ethylene (also called ethene) produced during refining and other chemical treatments. Fundamentally, of course, ethanol is made from, in the sense of constituted of, carbon, hydrogen, and oxygen.
