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

water and‚ more recently‚ generation of electricity. Contemporary electricity-generating versions are referred to as wind turbines. In the context of our country‚ where we continually suffer from load shedding‚ windmill sounds like a creative solution. Although the idea of setting up windmills here is a new idea‚ the concept is lot older. We have the “Kaptai Dam” in “Karnafuli” where we use the force of water to produce electricity which is based on the same principle.

conducted in association with a second laboratory that measured the effects of an inhibitor on the enzymes. Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration were the conditions tested in the experiment. Each lab was assigned to a group A‚ B‚ C and D in our class performed this experiment. The data presented in this report will reflect the average rates of change in O2 ml/min of our class results. In the later discussion sections‚ it will become

individually to receive the most accurate results. Preparation for the lab began with selecting a medium to large spinach leaf and deveining it. Once the spinach was prepared‚ it was ground in 5 mL of 100% acetone‚ creating a green acetone extract. The extract was filtered through a funnel with a kimwipe and into a test tube. The volume of the filtered extract was estimated‚ and one half of the estimated volume of petroleum ether was added to the solution‚ along with two drops of water. The test tube

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

Writing of Lab Reports __________________________________________________________________________ W hy should I bother writing lab reports in the correct way?” The Foundation Programme is designed to prepare you for undergraduate studies at UTAR which will require the writing of lab reports all years generally. At the end of your third year‚ you may have an opportunity to work on scientific projects which will culminate in an official scientific report. Depending on the quality of your report

differ slightly from those in the book because their expected excess returns and covariances have been calculated in another spreadsheet and are shown in rounded form. For a good summary of how these calculations are done‚ see BKM‚ pp. 234-239. The solutions I obtained are given in the table below. There may be some variation from these results if you started with different initial weights. Such variations are to be expected in a multidimensional optimization problem. Long/Short Min. Var.
