1 2-Propanediol Analysis
final major of their metabolism. MICROORGANISMS PRODUCING 1, 2-PROPANEDIOL Wide ranges of bacteria are acknowledged at present to ferment sugars for 1, 2-propanediol. The manufacture of this diol accounted in bacteria and yeast. Enebo as early as in 1954 reported Clostridium thermobutyricum to generate 1, 2-propanediol. Suzuki and onishi were the first to inform propanediol as being an entity to produce yeast. Ten years afterwards, Bacteroides ruminicola was cited as manufacturer of this diol by Turner and Robertson. They, both deliberated the metabolism and growth of b. ruminicola defer grown on rhamnose, where it has been observed experimentally that rhamnose has mainly fermented to 1,2-propanediol, xylose and arabinose. A path of straight …show more content…
Salmonella typhimurium account 1,2-propanediol, de-oxy sugars. Identify an equimolar extent of 1, 2-propanediol when (methyl pentose), rhamnose or fucose was used as substrate. However, still 1, 2-propanediol is not further metabolized by anaerobic cultures, and will disappear gradually from the middle in s. typhimurium cultures maintained in similar surroundings. This meticulous inquiry discovered that when grown on rhamnose, s. typhimurium excreted 1.0 M 1, 2-propanediol/m of sugars in the middle. Now, after collapse of the sugar, the diol concentration has arrived to its maximum and step by step it departed when the culture was kept in the same conditions for more time. Vanishing of these diol did not occur at all when cells were removed from the medium by the process of centrifugation. Veiaga da Cunha and Foster reported for the first time Lactobacillus brevis and l. buchneri can also produce 1, 2-propanediol degrading lactic acid using glycerol as an electron acceptor. This new way of production of 1, 2-propanediol was described by Elferinketal elsewhere. While studying on l. buchneri and l. parabuchneri. These Lactobacilli were capable of degrading lactic under anoxic conditions, without requiring an peripheral electron acceptor. Here again, each mole of lactic acid has been altered into approximately 0.50001 M acetic acid, 0.50002 M in 1, 2-propanediol and traces of ethanol. Furthermore the acidic conditions are necessary to produce the acid lactic cells degrading the

This Way For The Gas Ladies And Gentlemen Analysis
1274 Words | 6 PagesThere are countless pages written by many authors detailing the accounts of the Holocaust. Some of these authors experienced the brutality and horrors of life in a concentration camp first-hand; while, others wrote about their experiences from outside perspectives. In this essay, two of these authors will be compared to one another in order to answer the question of how one tells a survivor’s story. Moshe Flinker, a young Jewish diarist living in Belgium, and Tadeusz Borowski, author of This Way for the Gas, Ladies and Gentlemen, will be compared on the methods that each writer uses to describe their respective experiences, the perspective from which each narrative is told, and the outlook that each author portrays regarding their own futures after the war.

They were kept the same size to ensure accurate results. A control test was conducted in distilled water to obtain a result to compare. The ethanol treatments were 40% and 70%.
Battle Of Thermopylae Analysis
227 Words | 1 PagesThere were 9,000 Persian soldiers at the Battle of Thermopylae. According to Document B written by Ctesias, who was alive at the time of the battle” claims that he has access to the Persian archives in 398 BCE. In these archives he discovered this quote “His general Artapanus, with 10,000 men fought at the battle of Thermopylae”. Since Ctesias was a Persian I believe that he might have exaggerated the number of soldiers to make his country look greater and stronger. Another piece of evidence is that in Document C ,written by Ernle Bradford, a secondary source, states that their wasn’t enough water to support the previously estimated 210,000 Persian Soldiers but their was enough water for 9,000 soldiers.
Bulk Fermentation Process
1332 Words | 6 PagesThis is the second step. During fermentation, from a rough dense mass lacking extensibility and with poor gas holding properties, the dough slowly changes into a smooth, extensible dough with good gas holding properties. As the yeast cells grow, the gluten protein pieces clump together to form networks. Hence, the alcohol and carbon dioxide are formed from the breakdown of carbohydrates that are found naturally in the flour. Enzymes present in yeast and flour also help to speed up this reaction.
Alcaligenes Faecalis Experiment
636 Words | 3 PagesAccording to the series of test that my group ran for our unknown specimen, we had a match with the bacteria known as Alcaligenes Faecalis. This bacterium belongs to one of the major group of gram-negative bacteria (Phylum Proteobacteria). Alcaligenes Faecalis (Genus, species) is a rod shaped (bacillus), 0.5-1.2 x 1.0-3.0 µm, round with scalloped margin (colony configuration growth), motile (with one to nine peritrichous flagella), gram-negative, non-fermentative bacteria, obligate aerobic, having oxygen as the principal terminal electron acceptor in the electron transport chain (ETC). We consider we have a match with the species Alcaligenes Faecalis because of the following reasons: Fermentation tests performed (Durham sugars) were negative, which indicate that our bacteria use a different metabolic means for growth (non-fermentative gram-negative bacteria).
Yeast Fermentation Lab
529 Words | 3 PagesTitle: How Ph Levels Affected the Fermentation of Beer Hypothesis: The beer will be left with more sugar deposit as the Ph levels increase because alpha/beta -amylase will no longer function. Predictions: Alcohol Percentage Analysis for the Control and the Experimental During this experiment, the pH level was increased, therefore Alpha-Amylase was favored. Due to the nature of Alpha-Amylase cutting randomly through a large carbohydrate molecule, it leaves bigger sugars in the flask, which cannot be digested by yeast. Due to this, less reactions should occur in the experimental, therefore leading to a lower percentage of alcohol production, compared to the control.
Cellular Respiration Research Paper
1393 Words | 6 PagesFor example, fermentation occurs in yeast in order to gain energy by transforming sugar into alcohol. Fermentation is also used by bacteria, they convert carbohydrates into lactic acid. Ethanol fermentation is done by yeast and certain bacteria, when pyruvate is separated into ethanol and carbon dioxide. Ethanol fermentation has a net chemical equation: C6H12O6 (glucose) > 2C2H5OH (ethanol) + 2CO2 (carbon dioxide). This process of ethanol fermentation is used in the making of wine, bread, and beer.

Many are puzzled by how the production of cyclohexane seems to have become stagnant. Perhaps this is due to the cost of benzene increasing or the demand increasing. Through thorough investigation, the answer to this question and many more can be answered.
Phenol-Sulfuric Acid Analysis Essay
740 Words | 3 PagesThe results of the phenol-sulfuric acid analysis conducted in this experiment suggest that the data acquired was relatively precise but inaccurate with respect to the given carbohydrate concentrations of the soda and Gatorade samples. Using a standard curve generated from a glucose solution with a known concentration, the carbohydrate concentration of the samples was determined (in terms of glucose) and a low coefficient of variation was calculated. However, a high percent relative error was apparent in the analysis of both samples. This may have been due to the fact that the analysis was conducted assuming glucose was the carbohydrate of interest, while, in fact, a significant portion of the monosaccharides would have existed as fructose (a
What Happens When Can Yeast Metabolize?
451 Words | 2 PagesThese results accept the hypothesis: if yeast can metabolize, then the bromothymol blue solution should turn yellow from the production of carbon dioxide. Only the bromothymol blue solution with yeast turned yellow, suggesting that the yeast caused the color change. The yeast consumed sugar, produced

Introduction to Gas Chromatography Gas chromatography is a very powerful separation technique for compounds that are reasonably volatile. The components of a sample partitions into two phases, the 1st of these phases is a immobile bed with a great surface area, and the other is a gas phase that permeates through the immobile bed. The sample is evaporated and passed by the mobile gas phase or the carrier gas through the column. Samples separates into the stationary liquid phase, based on their solubilities at the given temperature.
