Title: Preparation and purification ethyl alcohol Purpose: The purpose of this experiment is to form a yeast mixture with water‚ organic compound like sucrose‚ Ba (OH) 2 for fermentation process‚ and use simple distillation method to purification from the fermentation mixture. Abstract and Theory: There are many techniques that are used to purify liquid. The one that is going to use for this lab is simple distillation. It is a process of which separating a mixture based on the tendency of the

ingredients and origin. Beer can be divided into 2 broad sub-categories: ale and lager. Ales were the first type of beer ever created before brewers knew the role yeast played during the beer making process. Ale yeasts flocculate at the top of the fermentation tank and are brewed from malted barley using a warm fermentation. The yeast ferments the beer quickly‚ which gives it a full bodied and fruity taste. They also contain hops‚ which gives the bitter herbal flavor that helps balance the sweetness

decolourized during the respiration of yeast. By measuring the time taken for a fixed amount of the dye to be decolourized‚ the relative rate of respiration (a catabolic process) can be deduced. Results: The yeast mixture in test tube A turned blue at first but slowly changed back to its original colour and stayed that way. The yeast mixture in test tube B turned blue and remained unchanged. The yeast mixture in test tube A are alive‚ whereas the yeast mixture in test tube B are dead. Reactions:

Abstract The experiment aims to observe if simpler substrates makes the rate of cellular respiration faster. Using yeast‚ smith fermentation tubes and different substrates namely‚ starch‚ lactose‚ sucrose‚ glucose and fructose‚ which are from different kinds of carbohydrates‚ ranging from the simplest sugars glucose and fructose to the polysaccharide starch and water as the control‚ the hypothesis was tested. With the span of thirty minutes with five-minute intervals‚ the height of carbon dioxide

The Variation of Yeast Cells When Adding an Antibiotic Biology 1401- A October 21‚ 2013 Abstract. -- The main focus in this experiment was to find out if antibiotics affect yeast cells culture when added. The observation of the two cultures along with the yield of yeast cell reproduction between the two cultures was the sole purpose of the experiment; culture-A (- antibiotic) and culture-B (+ antibiotic). Our hypothesis stated whether antibiotic effects yeast cells cultures. This theory was

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

It was hypothesized that glucose‚ sucrose and fructose would all produce energy through yeast fermentation‚ but that sucrose would have the greatest rate of energy production. The carbon dioxide production was tracked in the fermentation of yeast with solution of no sugar‚ glucose
