2.6.4 Vacuum drying Amellal and Benamara (2008) investigated the drying ability of date (Phoenix dactylifera L.) pulp cubes from three Algerian common varieties (Mech - Degla, Degla - Beida, and Frezza). Drying process was carried out under partial vacuum (200 mbar) at 60, 80, and 100° C. Compared to the Newton model, the Henderson and Pabis model better described drying kinetic of Mech - Degla and Frezza pulps at 60 and 80° C with a mean relative error (MRE) not higher than 6.07%. The same model

ABSTRACT: Cells are composed of various molecules that vary in structure and function. It’s important to study the treatment that these molecules receive when they enter the body after being occupied from the outside sources in the form of different nutrients. The purpose of this lab is to test the process of hydrolysis occurring in different macromolecules by using the biochemical tests. This lab also indicates the hydrolysis of macromolecules when heat or acidity is applied to the molecules or

A. Generate a fermentation profile for each of the organisms you tested. Glucose fermentation shows the ability of a bacterium to ferment carbohydrate as well as its ability to convert end products (pyruvic acid) into gaseous byproducts (Levinson, 2014). During this experiment 2 of the Staphylococcus epdidermidis tubes turned yellow. It was difficult to tell if there was an air bubble in any of the tubes that turned yellow, so I may be wrong on some of the fermentation profiles. The S. cerevisiae

sources. They contribute to the body’s structure and help regulate body processes. Some minerals help regulate water balance; others help regulate energy metabolism, and some effect growth and development. “Many minerals act as cofactors needed for enzyme activity.” (WileyPlus) Minerals interact with other minerals as well as other nutrients and other components of the diet. Water is the one nutrient that is often overlooked. It accounts for 60% of our body water and is found inside cells and

Ali Ahmad BIO 2710 Wed 12:30PM – 3:30PM Unknown 6: Micrococcus Luteus Introduction: This lab requires us to learn about cultural, morphological and biochemical characteristics that are used in identifying bacteria. These characteristics and unique aspects can be observed by learning and using the various different tests and techniques, which is the main purpose here, and can help pinpoint the identity of the unknown organism. Each student will receive a slant containing one species

Notes Enzymes: What must occur for a reaction to proceed? Collision Theory: 1. Reactants must collide 2. Reactants must have enough energy 3. Reactants must hit with proper orientation Here is morbid example of collision theory. How do a train and school bus react to give a train with engine damage and a school bus in two pieces? [pic] If you look back to the three conditions required for a reaction to occur, we can relate them to his terrible accident. In the collision theory, condition

Enzyme Regulatory Function Enzymes operate as catalysts by increasing and regulating all chemical reactions in a living organism within half the fraction of energy if they were not utilized. What makes enzymes so efficient and unique is that they can increase the rate of a reaction and alter chemical activity at the cellular level while still maintaining homeostasis and cellular equilibrium. In the absence of enzymes it would dramatically alter chemical reactions by decreasing the rate at which
