Case study - Essay Example This test is carried out to determine the contents of the milk that cause this kind of bleeding known as the blackout syndrome. There were various tests that were done on the two kinds of milk that were provided. They all have different objectives that will help in finding the cause of the black syndrome. The filter test is used to show the different type of microns that are contained in the middle; the Petri dish test is used to culture the milk for more studies; the atomic absorption flame photometer detects the presence and concentration of certain ions; the microscope test helps in the identification of the various shapes of the pathogens. The tests have different procedures, to culture the milk pathogens it is required to sterilize a nichrome loop, dip it into the liquid being tested and smear it across the agar in the petri dish. Repeat the same procedure on what is to be compared with and wait for the pathogens to culture. The atomic absorption flame photometer takes a certain procedure which as follows: prepare a solution of the substance to be tested, evaporate the solution to leave fine solid particles, burn the solid particles in the machine to produce a black strip with several distinct colors. To microscope test take the following procedure: take a small sample of the substance to be tested and add crystal violet to stain the cell, add iodine to fix the purple stain in some types of bacteria, wash everything in alcohol to decolorize the non-fixed bacteria, add a red counterstain and prepare the sample for viewing. The filtration test requires one to pour the substance to be tested into the machine and turn it on and wait for the wait for the machine to categorize the components of the test substance. The filter divides the components of the milk into three categories which shows the presence of different types of microns in the milk. Burning samples of the test product in the atomic absorption flame photometer shows a black strip with several disti nct colors. The petri dish test shows culturing in the milk sample in the dish. The microscope test helps to identify the shapes of the different types of bacterium in the milk. The filtration test shows the presence of fungi indicated by part of the milk that did not go into the 10 micron ending up in the F-100 bottle, the presence of bacteria indicated by the part of milk that has not gone through the half micron filter ending up in the F-five bottle. The culturing of pathogens in the petri dish indicates the presence of bacterium in the milk sample as indicated by the white pathogen growing in sample milk A. The different shapes of bacteria shown through the microscope show the types of bacterium in the milk (gram positive or gram negative) and their various colors. The results from the atomic absorption photometer indicate no poison in the milk since the readouts do not indicate anything out of normal. The filtration process indicates the different types of pathogens in the milk with regard to their sizes. The presence of the sample milk in bottle F100 indicate the presence of fungi while the presence of part of the sample milk in bottle F5 indicates the presence of bacteria and the presence of sample milk in bottle F0 indicates presence of viruses and chemicals in the milk. The identical coloration of the black strip in the flame photometer
