Product industry alcohol production

Production of industrial alcohol is an age old practice. But with time, the usage areas as well as production techniques have gone through a major transformation. Industrial alcohol is distilled ethyl alcohol C2H5OH , normally of high proof, produced and sold for other than beverage purposes. It is usually distributed in the form of pure ethyl alcohol, completely denatured alcohol, especially denatured alcohol and proprietary solvent blends.

When he drank the contents, he tasted a new, strange flavor. Suddenly his head was spinning, he laughed for no reason, and he felt powerful. He drank all the liquid in the jar. The next day he experienced an awful feeling. He had a headache, pain , an unpleasant taste in his mouth, and dizziness — he had just discovered the hangover.

You might think this is just a tale, but is it? Several archaeological excavations have discovered jars containing the remains of wine that are 7, years old McGovern, , and it is very likely that humankind's first encounter with alcoholic beverages was by chance. How did this chance discovery lead to the development of the beer and wine industry Figure 1 , and how did scientists eventually learn about the biological mechanisms of alcohol production?

Over the course of human history, and using a system of trial, error, and careful observation, different cultures began producing fermented beverages. Mead, or honey wine, was produced in Asia during the Vedic period around — BC , and the Greeks, Celts, Saxons, and Vikings also produced this beverage. In Egypt, Babylon, Rome, and China, people produced wine from grapes and beer from malted barley. In South America, people produced chicha from grains or fruits, mainly maize; while in North America, people made octli now known as "pulque" from agave, a type of cactus Godoy et al.

At the time, people knew that leaving fruits and grains in covered containers for a long time produced wine and beer, but no one fully understood why the recipe worked. The process was named fermentation, from the Latin word fervere , which means "to boil. Producing fermented beverages was tricky. If the mixture did not stand long enough, the product contained no alcohol; but if left for too long, the mixture rotted and was undrinkable.

Through empirical observation, people learned that temperature and air exposure are key to the fermentation process. Wine producers traditionally used their feet to soften and grind the grapes before leaving the mixture to stand in buckets. In so doing, they transferred microorganisms from their feet into the mixture. At the time, no one knew that the alcohol produced during fermentation was produced because of one of these microorganisms — a tiny, one-celled eukaryotic fungus that is invisible to the naked eye: yeast.

It took several hundred years before quality lenses and microscopes revolutionized science and allowed researchers to observe these microorganisms. All rights reserved. In the seventeenth century, a Dutch tradesman named Antoni van Leeuwenhoek developed high-quality lenses and was able to observe yeast for the first time.

In his spare time Leeuwenhoek used his lenses to observe and record detailed drawings of everything he could, including very tiny objects, like protozoa, bacteria , and yeast. Leeuwenhoek discovered that yeast consist of globules floating in a fluid, but he thought they were merely the starchy particles of the grain from which the wort liquid obtained from the brewing of whiskey and beer was made Huxley Later, in , yeast were defined in the Dictionary of the English Language by Samuel Johnson as "the ferment put into drink to make it work; and into bread to lighten and swell it.

In the eighteenth and nineteenth centuries, chemists worked hard to decipher the nature of alcoholic fermentation through analytical chemistry and chemical nomenclature.

In , the French chemist Antoine Lavoisier was working on basic theoretical questions about the transformations of substances. In his quest, he decided to use sugars for his experiments, and he gained new knowledge about their structures and chemical reactions. Using quantitative studies, he learned that sugars are composed of a mixture of hydrogen, charcoal carbon , and oxygen. Lavoisier was also interested in analyzing the mechanism by which sugarcane is transformed into alcohol and carbon dioxide during fermentation.

He estimated the proportions of sugars and water at the beginning of the chemical reaction and compared them with the alcohol and carbon dioxide proportions obtained at the end. For the alcoholic reaction to proceed, he also added yeast paste or "ferment," as it was called. He concluded that sugars were broken down through two chemical pathways: Two-thirds of the sugars were reduced to form alcohol, and the other third were oxidized to form carbon dioxide the source of the bubbles observed during fermentation.

Lavoisier predicted according to his famous conservation-of-mass principle that if it was possible to combine alcohol and carbon dioxide in the right proportions, the resulting product would be sugar. The experiment provided a clear insight into the basic chemical reactions needed to produce alcohol.

However, there was one problem: Where did the yeast fit into the reaction? The chemists hypothesized that the yeast initiated alcoholic fermentation but did not take part in the reaction. They assumed that the yeast remained unchanged throughout the chemical reactions. Gay-Lussac was experimenting with a method developed by Nicolas Appert, a confectioner and cooker, for preventing perishable food from rotting.

Gay-Lussac was interested in using the method to maintain grape juice wort in an unfermented state for an indefinite time. The method consisted of boiling the wort in a vessel, and then tightly closing the vessel containing the boiling fluid to avoid exposure to air. With this method, the grape juice remained unfermented for long periods as long as the vessel was kept closed. However, if yeast ferment was introduced into the wort after the liquid cooled, the wort would begin to ferment.

There was now no doubt that yeast were indispensable for alcoholic fermentation. But what role did they play in the process? When more powerful microscopes were developed, the nature of yeast came to be better understood. In , Charles Cagniard de la Tour, a French inventor, observed that during alcoholic fermentation yeast multiply by gemmation budding.

His observation confirmed that yeast are one-celled organisms and suggested that they were closely related to the fermentation process. The recognition that yeast are living entities and not merely organic residues changed the prevailing idea that fermentation was only a chemical process.

This discovery paved the way to understand the role of yeast in fermentation. Life out of nowhere? Nature , Our modern understanding of the fermentation process comes from the work of the French chemist Louis Pasteur Figure 2.

Pasteur was the first to demonstrate experimentally that fermented beverages result from the action of living yeast transforming glucose into ethanol. Moreover, Pasteur demonstrated that only microorganisms are capable of converting sugars into alcohol from grape juice, and that the process occurs in the absence of oxygen.

He concluded that fermentation is a vital process, and he defined it as respiration without air Barnett ; Pasteur Pasteur performed careful experiments and demonstrated that the end products of alcoholic fermentation are more numerous and complex than those initially reported by Lavoisier. Along with alcohol and carbon dioxide, there were also significant amounts of glycerin, succinic acid, and amylic alcohol some of these molecules were optical isomers — a characteristic of many important molecules required for life.

These observations suggested that fermentation was an organic process. To confirm his hypothesis, Pasteur reproduced fermentation under experimental conditions, and his results showed that fermentation and yeast multiplication occur in parallel. He realized that fermentation is a consequence of the yeast multiplication, and the yeast have to be alive for alcohol to be produced.

In , a man named Bigo sought Pasteur's help because he was having problems at his distillery, which produced alcohol from sugar beetroot fermentation. The contents of his fermentation containers were embittered, and instead of alcohol he was obtaining a substance similar to sour milk.

Pasteur analyzed the chemical contents of the sour substance and found that it contained a substantial amount of lactic acid instead of alcohol. When he compared the sediments from different containers under the microscope, he noticed that large amounts of yeast were visible in samples from the containers in which alcoholic fermentation had occurred.

In contrast, in the polluted containers, the ones containing lactic acid, he observed "much smaller cells than the yeast. Alcoholic fermentation occurs by the action of yeast; lactic acid fermentation, by the action of bacteria. By the end of the nineteenth century, Eduard Buchner had shown that fermentation could occur in yeast extracts free of cells, making it possible to study fermentation biochemistry in vitro.

He prepared cell-free extracts by carefully grinding yeast cells with a pestle and mortar. The resulting moist mixture was put through a press to obtain a "juice" to which sugar was added. Using a microscope, Buchner confirmed that there were no living yeast cells in the extract. Upon studying the cell-free extracts, Buchner detected zymase, the active constituent of the extracts that carries out fermentation.

He realized that the chemical reactions responsible for fermentation were occurring inside the yeast. Today researchers know that zymase is a collection of enzymes proteins that promote chemical reactions. Enzymes are part of the cellular machinery, and all of the chemical reactions that occur inside cells are catalyzed and modulated by enzymes.

ATP is a versatile molecule used by enzymes and other proteins in many cellular processes. Glycolysis — the metabolic pathway that converts glucose a type of sugar into pyruvate — is the first major step of fermentation or respiration in cells. It is an ancient metabolic pathway that probably developed about 3.

Because of its importance, glycolysis was the first metabolic pathway resolved by biochemists. The scientists studying glycolysis faced an enormous challenge as they figured out how many chemical reactions were involved, and the order in which these reactions took place.

In glycolysis, a single molecule of glucose with six carbon atoms is transformed into two molecules of pyruvic acid each with three carbon atoms. In order to understand glycolysis, scientists began by analyzing and purifying the labile component of cell-free extracts, which Buchner called zymase.

They also detected a low-molecular-weight, heat-stable molecule, later called cozymase. Both components were required for fermentation to occur. The complete glycolytic pathway, which involves a sequence of ten chemical reactions, was elucidated around In glycolysis, two molecules of ATP are produced for each broken molecule of glucose.

During glycolysis, two reduction-oxidation redox reactions occur. In a redox reaction, one molecule is oxidized by losing electrons, while the other molecule is reduced by gaining those electrons.

A molecule called NADH acts as the electron carrier in glycolysis, and this molecule must be reconstituted to ensure continuity of the glycolysis pathway. The nucleus black and mitochondrion red are also shown. When oxygen is available, pyruvic acid enters a series of chemical reactions known as the tricarboxylic acid cycle and proceeds to the respiratory chain.

As a result of respiration, cells produce 36—38 molecules of ATP for each molecule of glucose oxidized. In the absence of oxygen anoxygenic conditions , pyruvic acid can follow two different routes, depending on the type of cell.

It can be converted into ethanol alcohol and carbon dioxide through the alcoholic fermentation pathway, or it can be converted into lactate through the lactic acid fermentation pathway Figure 3. Since Pasteur's work, several types of microorganisms including yeast and some bacteria have been used to break down pyruvic acid to produce ethanol in beer brewing and wine making.

The other by-product of fermentation, carbon dioxide, is used in bread making and the production of carbonated beverages.

The important product methanol Figure 1 is obtained from synthesis gas in the form of carbon monoxide and hydrogen sometimes carbon dioxide and hydrogen. The terms methyl alcohol and methanol are synonymous, the former being used more in Great Britain and the latter expression universal in United States industry. The term wood alcohol, sometimes employed, refers to the fact that this alcohol was formerly obtained by the distillation of wood. Methanol is a large-volume chemical; about half of the production goes to making formaldehyde CH 2 O , a very reactive chemical with a large number of uses. A small amount of formaldehyde comes from non-methanol sources, via the direct oxidation of hydrocarbons. Methanol also enters into the production of various plastics; leads to such useful derivatives as methyl chloride , a solvent for inks and dyes; and is used in the purification of steroidal and hormonal medicines. The greatest uses of formaldehyde are in the formation of important groups of plastics, the urea-formaldehyde resins and the phenol-formaldehyde resins. In addition, it is used as a fungicide and as a preservative, in paper and textile treatments, and in the synthesis of further products.

In order to develop effective strategies to prevent alcohol-related harm on has to take into account the role of the vested interests behind production and sale of alcohol beverages. One of the key reasons behind increasing alcohol consumtion in developing societies is the aggressive marketing, and also the tough lobbying on national governments, from the big beer and liquour producers. Globalization of the alcohol industry is steadily increasing. A few major companies dominate the world market with their branded products. Is it the goal of globalization that young people should be able to get drunk on Carlsberg regardless of whether they live in Norway, Sri Lanka or Malawi?

Ethanol fermentation , also called alcoholic fermentation , is a biological process which converts sugars such as glucose , fructose , and sucrose into cellular energy , producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen , alcoholic fermentation is considered an anaerobic process. It also takes place in some species of fish including goldfish and carp where along with lactic acid fermentation it provides energy when oxygen is scarce. Ethanol fermentation has many uses, including the production of alcoholic beverages , the production of ethanol fuel , and bread cooking. Alcoholic fermentation converts one mole of glucose into two moles of ethanol and two moles of carbon dioxide, producing two moles of ATP in the process.
