cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

Introduction Chemical kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

study a set of metals and their reactions reactions using different metals in an ordered activity series‚ the goal is to find the relative reactivity of them.Discovering why metals react with certain cations and solutions is the main point of this lab. This has many real life applications. When creating buildings‚ or bridges it is important to understand and counter-act the rusting of iron. You can do that by using the activity series. For any industry using metals‚ this is important. Manufacturing

to imagine dancing them. I found that the swirls could serve as a trajectory for different body parts or pathways‚ and the almost lackadaisical way in which he meshed colors inspired a smooth movement quality. One of his painting‚ Fritillaries in a Copper Vase‚ especially stood out to me choreographically. The way in the flowers laid downward reminded me of hands potentially

Copper (II) Sulfate Purpose: The purpose of this lab is to find out how many moles of water there are in one mole of Copper Sulfate (CuSO x HO) and the percent by mass of water in the hydrate. This will be accomplished by heating a determined mass of the hydrate to remove the water‚ and by measuring the salt left over. Introduction: This laboratory experiment will be done to find out how many moles of HO are present per one mole in the hydrate CuSO. A hydrate is a compound that has a fixed number

Eric Bryan Period 4 Calorimetry Lab Theory: To most people heat and temperature are generally the same thing. But really in a scientific sense there is still a similarity between them but they are different concepts. Temperature is the measure of the average energy of molecular motion in a substance. Heat is the total energy of molecular motion in a substance. Temperature is not energy like heat is‚ it is just measure of it. Now there is also a difference between heat and thermal

My lab results were similar to my hypothesis. My hypothesis was that the densest object would be the rubber stopper. In the lab results the densest object was the penny and the rubber stopper was second. My hypothesis was switched. My hypothesis was correct when I stated that the macaroni was the third densest object. My hypothesis was also correct for the dice‚ but the bead and the dice share the same density. So they are both the fourth densest item. I was wrong with my hypothesis when I placed

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise
