one rubber stopper‚ one bubbler‚ one measuring beaker‚ 2 ml of yeast‚ 10 ml of warm water‚ and 30 ml of corn syrup. The first step we took was taking the measuring beaker‚ measuring 10 ml of warm water‚ and adding the 10 ml of warm water to the fermentation bottle. We then took the measuring beaker again‚ measured 2 ml of yeast‚ and added the 2ml of yeast to the warm water in the fermentation bottle. After that‚ we mixed both yeast and water gently until it was thoroughly dissolved. Then we took

Biology Lab report #1 The uptake of neutral red dye in a yeast cell using different solutions Abstract Every cell transports materials in and out throught something called a membrane. There are many different methods of transport in the cell Saccharomyces cerevisiae (Serrano‚ 1977) We want to know does adding higher concentrations of azide more effectively block dye transport? We tested the transport of dye in yeast cells with a metabolic inhibitor. When we did this we showed no difference

APPENDIX 5 - Writing Reports Report 1: Drosophila F1 Generation Report General Notes: This report is very much a practice run to get you used to this style of report writing‚ rather than simply filling in lab sheets. It should not be a long report (no longer than these notes‚ in fact). Scientific writing is not like writing essays in other genre. In many ways it is easier! There are three important rules to scientific writing and if you adhere to these‚ the rest is quite easy: 1. Sentences

PEST POLITICAL ECONOMIC Over the years‚ the Philippines has gone from being one of the richest countries in Asia to being one of the poorest. It has experienced growth and development since World War II. The current administration under President Gloria Macapagal-Arroyo is aiming for a more rapid growth in the coming years. In 2004‚ the Philippine economy grew by 6.1% surprising everyone. In 2005‚ the Philippine peso appreciated by 6%‚ the fastest in the Asian region for that year

how starch and cellulose are treated to allow them to be used by the yeast? One potential ethanol feedstock is starch. Starch molecules are made up of long chains of glucose molecules. Thus‚ starchy materials can also be fermented after breaking starch molecules into simple glucose molecules. Examples of starchy materials commonly used around the world for ethanol production include cereal grains‚ potato‚ sweet potato‚ and cassava. A great amount of ethanol fuel is currently produced by starch

The Fermentation and Distillation of Alcohol By Bhanupriya Chettiar 301 Group Members: Bhanupriya Chettiar‚ Rachel Min‚ Zoe Chandler‚ Bianca Main Aim The aim of the practical is to prepare ethanol by fermentation and to isolate it by fractional distillation. Introduction This practical’s aim is to prepare ethanol using two steps; fermentation and then fractional distillation. Many alcoholic drinks for example‚ brandy and whisky‚ are prepared using this method but to a larger scale. The first

To determine what conditions make dough rises best Apparatus and materials Flour Yeast Warm water Sugar Mixing bowl Two (2) beakers Measuring cup Spoon Diagram of Apparatus Method 1. Take a measuring and measure 1 and ½ cups of warm water 2. Add yeast then sugar (this is used to activate the yeast. The yeast uses the sugar and water to create carbon dioxide and raise the bread) 2. Add the yeast mixture to the mixing bowl along with ¾ of flour 3. Mix the ingredients with a wooden

excellent value nutritionally‚ and of great importance to vegetarians. Edible mushrooms are excellent sources of protein‚ have low-fat content and are free of cholesterol. They are easily cultivable and are consumed either in fresh or processed form. Yeasts and filamentous fungi secrete a plethora of important enzymes in the growth medium together with other secondary metabolites. Most of these are hydrolytic in nature being employed in different food processing industries as well as in refinement of

The organism used for this experiment was Saccharomyces cerevisiae (S. cerevisiae) which is often called baker’s yeast. S. cerevisiae has several characteristics that make it an ideal organism to use in experiments. S. cerevisiae is a single-celled eukaryote capable of reproducing through mitosis or sporulation. This means that the yeast has both a haploid and a diploid stage. In yeast‚ the haploid cells are n=16 and the diploid cells are 2n=32. S. cerevisiae has two haploid mating types MATɑ and
