How well did you meet your individual food recommendations (food groups‚ amounts‚ variety)? I did not meet my individual food recommendations very well. For grains‚ I reached my food recommendations more than any other food group. Since‚ I come from a Vietnamese household‚ rice is eaten at almost every meal; however‚ the rice we eat is white jasmine rice which is a refined grain. On that particular week‚ I frequently ate peanut butter sandwiches for lunch which contributed to my grains. I rarely

ique bacterial strains of E. coli by observing the proper responses of wild type E. coli Lac Operon as a control group. Mutated strains of E. coli were placed in four test tubes‚ each containing a different substance (lactose‚ glucose‚ water and lactose and glucose). After a warm water bath‚ Sarkosyl detergent‚ toluene and ONPG were added to the tubes and incubated again. The data was qualified by observing the color change from clear to yellow to indicate the presence of lactase

FERMENTATION THROUGH DIFFERENT KINDS OF SUGARS In order to produce ethyl alcohol fermentation‚ we had to determine what sugars used‚ such as glucose (a single sugar) sucrose (table sugar) and lactose (milk sugar) will react with yeast to produce ethyl alcohol fermentation. My hypothesis is that the sugar lactose would produce the highest amount of bubbles and ferment. INTRODUCTION: The significance of fermentation is a lengthy process that has been practiced by humankind for thousands of years

Gene Expression Introduction: Escherichia coli are capable of using lactose as their sole carbon source. E. coli produces the enzyme β-galactosidase to digest the lactose into glucose and galactose. However‚ it would be inefficient to produce enzymes when there is no lactose available‚ or if there is a more readily-available energy source available such as glucose. Therefore there must be something controlling the expression of this enzyme. The purpose of the experiment is to determine whether

* The main (starter) cultures in yogurt are Lactobacillus bulgaricus andStreptococcus thermophilus. The function of the starter cultures is to ferment lactose (milk sugar) to produce lactic acid. The increase in lactic acid decreases pH and causes the milk to clot‚ or form the soft gel that is characteristic of yogurt. The fermentation of lactose also produces the flavor compounds that are characteristic of yogurt. Lactobacillus bulgaricus andStreptococcus thermophilus are the only 2 cultures required

MacConkey (also McConkey) agar is a culture medium designed to grow Gram-negative bacteria and stain them for lactose fermentation. It contains bile salts (to inhibit most Grampositive bacteria‚ except Enterococcus and some species of Staphylococcus)‚ crystal violet dye (which also inhibits certain Gram-positive bacteria)‚ neutral red dye (which stains microbes fermenting lactose)‚ lactose and peptone.

Abstract: Introduction: An operon is a group of genes that are arranged side by side with a regulatory gene. It also includes a promoter gene‚ operator gene‚ structural genes. Regulatory genes control transcription with positive or negative signal. (Jacob‚ and Monod‚ 1961) A positive signal‚ inducer‚ would stimulate

of energy which is needed for good growth and development of the body and the brain‚ especially for growing up children. Sugars are a type of carbohydrates. Milk which is a natural product in itself also contains sugars known as lactose. It is this sugar (lactose) in milk which helps your child to grow. Therefore‚ all Growing Up Milk will contain some form of sugars. 2. Tell me about the sugars in Dutch Lady’s Growing Up Milk. First of all‚ at Dutch Lady Malaysia we have developed a well
