    The population of the United States made some serious sacrifices during World War II. Gasoline rationing caused a major upheaval in the taxi and trucking industry and production of non war related item was curtailed. Sugar was limited to minuscule amounts on certain days of the month and people hoarded it as if it were gold. One of the most damaging curtailments was the production of beer due to the restrictions placed on barley. All the small "mom and pop" breweries could not afford to shut dow...

    Planning PROBLEM TO BE INVESTIGATED Yeast enzyme specificity: Specificity of Brewers and Bakers yeast enzymes to different sugars (being monosaccharides) HYPOTHESIS I predict Bakers yeast to have a different enzyme specificity compared to Brewers yeast where more CO 2 is produced at 37 0 C. BACKGROUND KNOWLEDGE Fermentation is the breakdown of sugars by bacteria and yeast using a method of respiration without oxygen (anaerobic respiration). It involves a culture of yeast and a solution of sugar,...

    Table of Contents Introduction Page 1 Experimentation Page 1 Discussion Page 2 Conclusion Page 2 Acknowledgments Page 2 References Page 3 Introduction My experiment was with yeast and the best food for it. I wanted to know what would make the yeast grow better. I used corn syrup, gelatin, grape juice and flour mixed with water. I thought that the corn syrup, which is high in processed sugars, would produce the make the most carbon dioxide gas. Carbon dioxide is a by-product made when yeast repr...

    Harry Fox 11 ST Biology Science 1 - Strand 1: Planning Aim In my experiment, my aim is to find out any correlation between rate of respiration of glucose by yeast and the mixtures temperature. I shall do this by conducting an experiment which will involve the timing of the yeast, water and glucose which has been mixed with a little methylene blue. I shall time how long it takes to revert to the original colour using a control. This shall be done at various temperatures. To obtain the best range ...

    Biology Lab Report Investigating Alcoholic Fermentation and the Affects of Yeast on Dough Aim: The aim was simply to investigate whether or not yeast had any affect on causing dough to rise when baked and to experiment with alcoholic fermentation eg. to see if it gave off carbon dioxide. Introduction: Following a few weeks of fermentation theory, groups of three to four were assigned and told to conduct a series of experiments involving the affects of fermentation. My group consisted of myself, ...

    Introduction There are thousands of different styles of beer in the world today but the one thing they all have in common is that the brewing process has been the same for 4, 500 years (Papazian, 2003). The steps are basic: clean the equipment, make the wort, ferment, and bottle. There are many books on brewing beer and they are exhaustive with theory. This being the case, the fermentation process, and the bottling will not be cover herein. By following these simple instructions, anyone can make...

    INTRODUCTION Microorganisms such as bacteria, fungus, mold, and yeast are present and common in almost every environment on earth. The normally microscopic organisms can easily be seen using differing types of agar, which creates an ideal environment for the organisms to form colonies, which are groups of hundreds of organisms that can be seen with the naked eye. In order to see individual microorganisms, it is necessary to use the magnification of a high-powered microscope. These techniques of ...
  • The Relationship Between Food Concentration And Respiratory Activity

    The Relationship Between Food Concentration, and Respiratory Activity In this experiment different concentrations of sucrose were tested to determine which leads to the most respiratory activity in yeast. Yeast is a heterotrophic anaerobic fungus which lacks chlorophyll. Yeast is used commercially to ferment the sugars of wheat, barley, and corn to produce alcohol, and in the baking industry to raise or expand dough. Yeast or alcoholic fermentation is the anaerobic process of respiration by whic...

    Fermentation InvestigationPlanningAs a culture of yeast is merged with solution of sugar, a reaction called fermentation occurs. As products, ethanol and carbon dioxide are produced, in form of liquid and gas respectively. The reaction follows this equation: Glucose solution + Yeast Carbon dioxide + Ethanol + (Energy) And as one of the products is in the form of gas, the volume of the product can be measured to demonstrate the difference of the reaction when certain factors are changed. In the o...

    What causes moldy bread and foods? How can you stop it? If you understand what fermentation is and how yeast survive you can answer these questions. Fermentation is the conversion of pyr uvic acid into other compounds such as lactic acid or ethyl alcohol. Fermentation occurs when cells do not have oxygen. Some Organisms that use fermentation are fungi and bacteria. Yeast are a type of fungus that uses fermentation for cellular respiration. This experiment tests at what temperatures yeast can per...
  • Catalase And Hydrogen Peroxide Sc1

    Aim: To investigate the effect of temperature on the enzyme catalase. Prediction: Using my existing scientific knowledge, I predict that as I raise the temperature to 30, 35, and 40, this is where we will see the greatest reaction. I predict this because enzymes are designed to react best at the body temperatures of the animals to which they belong. For a mammal, this is around 35-36. Catalysts are used to speed up biochemical reactions in the body. An enzyme is a protein molecule that speeds u...

    Cryptococcosis is a chronic mycotic infection caused by Cryptococcus variation and Cryptococcus var. gatt ii, both considered opportunistic. Though the organism is usually harmless to humans, the yeast type fungus can severely affect those with severe immunosuppression, such as HIV and AIDS patients. In 1894 Greifswal Medical Society was presented with a paper by a pathologist named Busse, stating that he managed to isolate yeast from a woman! |s tibia. It was noted the resistance to sodium hydr...
