desired specimen. It also took practice in adjusting the light source so as to have the proper contrast and brightness. In the end the practice using the prepared slides allowed for clear observation of the various bacterial cell shapes such as cocci‚ bacillus‚ and spirillium. These shapes were more easily identified in the prepared slides and this knowledge was used to view similar structures in the fresh yogurt slide. Finally‚ analysis of a blood smear was interesting because it was initially very hard

Microbiology UNKNOWN LAB REPORT Kateryna Petrakova INTRODUCTION Microorganisms cause a great amount of diseases. For healthcare providers it is very important to be aware of what organisms are pathogenic and cause a disease and‚ therefore‚ to find an appropriate treatment. Different microorganisms require various environments in order to replicate and to become dangerous for a person’s health. An integral part of any medical treatment is to be able to recognize and

Loh Pei Ting Peggie Introduction The 21st century has presented a major set of converging threats as the pressures of population growth‚ climate change and food insecurity are driving the world towards worsening hunger and malnutrition. Many people argue that Genetically Modified (GM) crops are promoted as a ‘Miracle Solution’ to solve the food shortage crisis since the use of genetic engineering enables genetic materials to be modified and in turn creates new varieties that exhibit desirable

experiment carbohydrate catabolism was first tested under aerobic conditions. We began this by drawing three sections on the bottom of the petri plate‚ dividing it into three sections. Using a sterile loop‚ we streaked a single line of each culture Bacillus subtilis‚ Pseudomonal aeruginosa‚ and Escherichia coli‚ to each of the separate sections. The plate was incubated until the next lab period‚ where we then flooded the plate with Iodine and were able to observe and record starch Hydrolysis. (Table
