Unknown reports in microbiology are written in scientific format. Scientific writing is written differently from other types of writing. The results of the exercise or experiment are what are being showcased‚ not the writing. The purpose of scientific writing is not to entertain‚ but to inform. The writing should be simple and easy to understand. There is a specific style that must be followed when writing scientific reports. Scientific writing is typically written in the passive voice. The

Bacteria: a benefit or a hazard? Bacteria is something we are all reminded of on a daily basis by merely switching on our televisions where we are bombarded with advertisements for both ‘good’ and ‘bad’ bacteria. Contrary to the view of the past when only so-called ‘bad’ bacteria was ever talked about‚ so what has changed? This essay will address the facts about bacteria including methods used in identifying bacteria as well as looking at specific examples of how they can be both helpful and harmful

Effects of Different Antibiotics on Bacteria Because of their small size‚ rapid rate of reproduction‚ and relatively simple structure‚ bacteria are excellent subjects for laboratory studies. This investigation will introduce you to techniques of microbiology that will be of use to you throughout your biological work. Procedure 1. Heat the test tubes of sterile agar medium in the water bath until the agar melts. 2. Remove the test tubes from the water bath. Let them cool enough to hold in your

over 99% of bacteria or antibiotics aren’t discovered. However‚ recently a new antibiotic called teixobactin was discovered. This antibiotic prevents the synthesis of a cell wall by binding to a motif of lipid II and lipid III molecules. The goal of this experiment was to discover how teixobactin interact with bacteria and how it is able to effectively kill pathogens. A device called the iChip was used to discover teixobactin. The iChip helped to isolate and grow uncultured bacteria. Multiple iChips

Many types of projects are possible when you are able to count bacteria. For example‚ you could count the bacteria in drinking water‚ fresh milk‚ old milk that is slightly sour‚ buttermilk‚ yogurt‚ mud puddle‚ lemonade‚ and many other things. Or you may want to know how fast Chlorox kills bacteria. If you add some Chlorox to a culture and count the surviving bacteria at suitable intervals you can plot killing the killing curve and determine whether the killing is single hit or higher order. It will

Anaerobic respiration in Bacteria Like humans and other animals‚ bacteria need to breathe. Anaerobic bacteria basically mean bacteria that respire anaerobically. All living cells need to respire in order to release energy for vital cell activities. Anaerobic respiration is respiration in the absence of oxygen‚ hence anaerobic bacteria does not breathe at all. The purpose of respiration is to provide the cell with the appropriate molecules for creating energy in the form of adenosine triphosphate

Flesh-eating bacteria strikes in Florida On June 16th‚ 26 year-old Cason Yeager went for a swim in Florida in Hernando County and later died from contracting the flesh-eating bacteria‚ Vibrio Vulnificus. This bacteria can be found worldwide‚ most particularly in the warm coastal regions but there have been reports in other parts of the world in non-warm waters. According to the CDC in 2013‚ the case count of the vibrio vulnificus was 104 in thirteen states with six hospitalizations. No deaths‚ but
