  1. 1. Saccharomyces is a ______________ in the kingdom of ______________ that includes many species of yeast. One of the most commonly used funguses in biotechnology is _______________________________. <br />Brewing Alcohol<br />Eg. Wine and beer <br />Wine and beer are ________________ using ______________ from the genus saccharomyces. <br />Alcoholic Fermentation in General: <br />* Fermentation is a chemical conversion of __________________ into ______________ and ____________________. <br />When _______________ is absent, the yeast switches to __________________________________ aka fermentation, and excretes _______________ and ______________________. <br /> Ethanol concentration around the yeast cell can rise to approximately_________ by volume (before toxic and fermentation ends) <br /> Carbon dioxide bubbles out into the atmosphere <br />Brewing Wine and Beer: <br />Saccharomyces in Wine Production<br />Crush grapes to make juice, place into vessels or vats <br />- <br />- <br />Few days later the oxygen in the juice is used up <br /> <br />Fermentation ends, Wine produces <br />- <br />- <br />In the case of Champagne Production…<br />- <br />- <br />Saccharomyces in Beer Production<br />Barley grains germinate <br /> <br />Barley seeds dried after few days <br /> <br /> <br />Mix malted barley with other sources of starch, selected variety of yeast and water into a vat<br />- <br />- <br />In the case of Guiness Beer Production… <br />- <br />- <br />Smart way of saying “yeast” is…________________________________________ takes place and releases Carbon dioxide and Ethanol. Carbon dioxide _____________ dough, increase its volume Ethanol is evaporated Oven heat eventually kills the yeast ____________________________. 4445414020Saccharomyces and Baking:<br />Soy Sauce Production: using Aspergillus Oryzae <br />It takes ______ months to make soy sauce. <br />It involves a fungus called _________________________ (sounds and looks like asparagus, but apparently its not. So its kinda like asparagus spell from Harry Potter) <br />How to make: <br />1. <br />2. <br />3. <br />4. <br />5. <br />Food Preservation<br /> Food preservation is to prevent the growth in microbes in food <br />AcidEg. - - SaltEg - - SugarEg. - - <br />Food Poisoning<br />-1174757620Most common form of food poisoning is caused by certain strains of: _________________________________________<br />General SymptomsMethod of TransmissionEg.TreatmentAim: Oral Rehydration Fluids:Intravenous Fluid: Antibiotics: <br />Salmonella Food Poisoning: <br /> contaminated food not properly cooked, cutting board (after cutting raw meat) not washed, raw eggs <br />
