IV. MATERIALS AND METHODS Process Description The classical penicillin production process is an aerobic fermentation in fed batch fermenters made with some Penicillium strains‚ usually Penicillium chrysogenum (Nielson‚ 1997) that transforms substrates rich in carbohydrates into penicillin. As with other antibiotic production processes (Cunha et al.‚ 2002)‚ the penicillin process operated at antibiotics involves four stages. The incubation of the culture strain provides the seed that grows in

cream is coconut milk intended. The naming of nata de coco in Spanish because the Philippines had been a colony of Spain. Nata de coco is a dessert that looks like jelly‚ white to translucent and chewy texture. This food is produced from the fermentation of coconut water. Coconut water can be used as a medium for the production of nata de coco. Nata de coco is fermented coconut water with the help of microbe Acetobacter xylinum‚ a solid‚ white‚ transparent‚ sweet tasting chewy textured clan

To: From: Re: Louis Pasteur Louis Pasteur: Greatest Achievements Louis Pasteur was one of the most important scientists of our time. The foundation of our knowledge about health and disease comes from the discoveries of this one man. He made many discoveries and solutions for problems of the every day life that are still in effect today. Pasteur was born on December 27‚ 1822 in a little town called Dôle in the foothills of the Jura Mountains of eastern France. When he was five years old his family

the yeasts would compete with one another and fermentation would stop prematurely. Controlling pH Next the pH (acidity) of the grape pulp needs to be controlled. If grapes are too sweet‚ then their pH is too high (acidity too low) then less flavours are produced in the wine. The pH can be lowered by adding tartaric acid at the start of the fermentation process. Temperature Finally the temperature must be controlled throughout the process. Fermentation is an exothermic process (heat is produced by

ABSTRACT The hypothesis which states that the simpler the nature of substrate‚ the faster the rate of cellular respiration of yeast was tested using the smith fermentation tube method. The experiment used six smith fermentation tubes‚ distilled water and sugar substrates. It composed of six set-ups which used 15ml of 10% yeast suspension‚ 15 ml distilled water and 15 ml of their assigned sugar substrate namely: starch‚ lactose‚ sucrose glucose and fructose respectively. Set-up six was the

DESIGN: Research Question What effect does varying the alcohol concentration of yeast have on its fermentation? Introduction Fermentation is the stage during which most CO2 is produced. When no oxygen is available‚ yeast will switch to an alternate metabolic pathway utilizing sugars for energy and producing‚ primarily‚ CO2 and ethanol. Yeast divides rapidly in this phase‚ reaching its carrying capacity (about 50 million cells/ml) in the wort‚ or must‚ and remains suspended

Bread Troubleshooting Guide Holes in Bread Possible Causes Old Dough Follow proper fermentation time. Improper Mixing Overmixing weakens the dough and undermixing underdevelops the dough; each causes poor gas retention. Mix to proper dough development. Lack of Moisture in Proofer Dough forms a crust‚ trapping gas. Adjust proofer to proper humidity. Improper Moulding Set moulder properly to expel most of the gas. Moulder Rollers in Poor Condition Trapped gas in dough causes holes. Check and

Low Calorie Diet Versus Low Carbohydrate‚ What is the Difference? Comm/155 05/12/13 Sandra Davis Being overweight and obese has become an increasingly alarming problem in this country. In 2007 the Center for Disease Control stated that between 1980 and 2004 obesity prevalence doubled among adults‚ and over 34 percent of all American adults were overweight or obese in 2006. Obesity is known to cause an increased risk of many diseases‚ such as heart disease‚ high blood pressure‚ diabetes‚ and
