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

the semester‚ samples of bacteria were obtained from various sources. Two bacterial colonies were isolated from plates that were incubated in the lab and these bacteria became the basis for this project. The bacterial cultures were maintained and used for various physiological‚ cultural‚ and biochemical tests and observations over several weeks. The purpose of culturing bacteria over half the course of the semester was to learn various techniques used in microbiology labs and to subsequently utilize

experiment is to see how much bacteria can and will grow in common places in a typical high school. Common places can mean many things‚ including anything from water fountain spouts to computer keyboards. Such objects can hold up to 2‚700‚000 colony forming units per square inch (or CFU/in sq)(NSF). A colony forming unit is the unit used to find an estimate of the number of cells of a bacteria. This unit of measurement is commonly utilized in the subject of microbiology. Most commonly‚ a bacterium

Coccus is a term used to describe a type of morphology that helps us distinguish different kinds of bacteria. The cell’s morphology is only one of the many ways we can differentiate the different species. Looking at these bacterium underneath the microscope is an important step to determine which kind of species it is. All cocci bacteria are not gram positive‚ but this lab will examine only this kind because of their influence in human health. Staphylococcus Aureus is a gram-positive coccus bacterium

classification of bacteria is important to make easier manipulation on the bacteria for various purposes such as for medical‚ research‚ developmental‚ and biotechnicalfieldsThe cell wall is the basis for classification of bacteria according to the Gram stain. Accordingto the chemical make up of bacterial cell wall‚ a staining procedure‚ Gram stain‚ helps usclassify bacteria into two subgroups‚ The cell wall can stain either positive or negative‚depending on its chemistry.
