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 controlled set-up and did not contain any sugar substrate. The opening of the tube was covered with a cotton ball to prevent oxygen from entering. The set-ups were then observed every

When it comes to keeping the human body‚ nutrition is the most essential part of everyone’s life. If people do not have full control‚ it will affect the way they will be in the future. Any change to someone’s diet will change their body in the long run‚ whether it be positive or negative. It is quite apparent‚ especially in America‚ that the common person’s nutrition has gone down hill. Since the 1980s‚ the rate of obesity has inflated double the amount for adults and triple for children (“Obesity”

maltose‚ lactose and sucrose are used for testing reducing and non-reducing sugars. Glucose is monosaccharide while maltose‚ lactose and sucrose are disaccharides of carbohydrates. Monosaccharaides are the monomers which make up all other carbohydrates and cannot be broken into smaller molecules by hydrolysis. Disaccharides are formed from the condensation reaction between two monosaccharaides and are linked by glycoside bond. All monosaccharaides and some disaccharides such as maltose and lactose are

in order to determine the identity of the unknown organism. The tests performed to identify the unknown organism included Gram Staining‚ Fluid thioglycollate/aero-tolerance test‚ Methyl Red-Vogues Proskauer‚ SIM test‚ Lysine Decarboxylase test‚ Lactose Fermentation test‚ Simmons Citrate test‚ and TSI test. The Gram staining technique showed that the organism was Gram negative and bacilli shaped. The fluid thioglycollate test showed that the organism was a facultative anaerobe‚ meaning ATP can
