Yogurt Fermentation Yogurt is made by lactic acid fermentation. The main (starter) cultures in yogurt are Lactobacillus bulgaricus and Streptococcus 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 …

Effects of Sugar Revolution – Economic During the seventeenth century the pattern of the Landownership changed from small planters to wealthy individuals and the price of land became extremely high as sugar became more profitable in the Caribbean. Previously tobacco and the other cash crops …

Abstract Yeast is widely used for making bread, beer, and wine. People all over the world drink and eat those products. This projects looks at which fruit juice with a higher percentage of sugar will produce more fermentation. The original purpose of this experiment was …

Cellular respiration is defined as an enzyme mediated process in which organic compounds such as glucose is broken down into simpler products with the release of energy (Duka, Diaz and Villa, 2009). It is a series of metabolic processes and oxidation-reduction reactions. Oxidation of substrates, …

Syl Rogers Bio 210 Comparing Fermentation Rate of the S. cerevisiae Yeast in the presence of MgSO4, NaF and Sodium Pyruvate Hypothesis In the fermentation of rate of yeast, S. Cerevisiae, there will be a higher/ faster rate of ethanol production, However, using catalytic enzymes …

OBJECTIVE: 1. To distinguish the bacteria abilities to metabolize various substrates and end products formed. 2. To observe the growth of different bacteria species in term of structures and its morphology based on different chemical substance applied. 3. To observe physiological and immunological properties utilized …

Medium formulation is an essential stage in the design of fermentation process. Most fermentation media require liquid media, although some solid-substrate fermentations are also operated. Fermentation media must satisfy all the nutritional requirements of the microorganisms and fulfill the technical objectives of the process. There …

The aim of this work was to identify how sugar concentration does affect yeast fermentation. An increase in sugar concentration must increase the release of CA as a result of yeast fermentation. The following analysis considers the average CA concentrations measured as a result of …

Fermentation is anaerobic respiration whereby food is altered into more simple compounds and energy in the form of chemicals is produced, an example being adenosine triphosphate (biology-online. org/dictionary/Fermentation). All this occurs with the lack of atmospheric oxygen. At the end of the day alcohol and …

The objective of these “unknown” experiments was to take a mixed culture, which contains two unknown species, and identify those species through a series of tests. The group was informed that one species of bacteria would be a gram-negative bacillus and the other would be …

 Questions A. Give two reasons why we fill the gas generator test tubes almost to the top with chemicals? The first reason is that we want to obtain pure gas and by minimizing the amount of air in the top this will maximize the gases …

All cells need to have a constant energy supply. The two processes by which this energy is attained from photosynthetic materials to form ATP are cellular respiration and fermentation. (Hyde,2012). Fermentation is a way of harvesting chemical energy that does not require oxygen. (Reece et …

Title of the Experiment: Enterobacteriaceae Identification: The Enterotube II System Learning Objectives: After completing this exercise we were able to inoculate an unknown bacterium that belongs to the Enterobacteriaceae by using technology effectively with a Enterotube II. An Enterotube II is a miniaturized multi-test system …

Cellular Respiration Study Guide 1. What is cellular respiration? Cellular respiration is the process by which cells get their energy from food. It is a pathway where ATP is produced from the working cells. 2. What are the raw materials for cellular respiration? The raw …

Interdependence In Nature Many of the relationships between organisms in nature are those of dependence. Whether it be a deer breathing oxygen produced by a nearby tree or a tick sucking the blood of its unsuspecting host, every organism depends on another organism in some …

In view of the commercial importance of black tea and the intricacy of the mechanisms of its manufacture, this product has received by far the most attention and the purpose of the present article is to outline some findings in this field. The black tea …

OBJECTIVES: To determine the amount of anti-microbial peptide production by Staphylococcus warneri under various conditions when 2L and 10L Fermented. To Test the effects of one uncontrolled parameters sush as pH, Temperature or dissolved Oxygen and compare findings. To produce anti-microbial activity from Staphylococcus warneri. …

Cell membranes are a bilayer make up of phospholipids, proteins, and cholesterol. Its main function is to regulate what comes in and out of the cell by means of diffusion, transport proteins and protein channels. Trans membrane proteins transport polar solutes across hydrophobic regions of …

Rising energy prices and environmental problems led to the increase in alcohol demands in many aspects, like in making fuels. Many people are doing researches about making their own product so as to lessen their everyday expenses. Right now, Filipino scientists are in think of …

Alexandra Mitchell Dr. Lamont King GAFST 200 November 30, 2010 Sugar Cane Alley Jose understands at a young age that in order to escape the indentured life of working in a sugar cane plantation like his ancestors before him, he must do something different. In …
