The purpose of the following study is to determine where the two unknown bacteria acquired in Microbiology lab should be classified in regards to temperature‚ pH level‚ and osmoregularity. It is important to classify bacteria in order to identify them. Identification of bacteria is important because they are not only useful but potentially dangerous as well. The identification of bacteria can lead to breakthroughs in healthcare regarding treatment of old and new diseases alike. Identifying bacteria

A Basic Understanding of Microscopy Assignment 1 Kaplan University-Microbiology Since microorganisms are not visible to the eye‚ the essential tool in microbiology is the microscope. One of the first to use a microscope to observe microorganisms was Robert Hooke‚ the English biologist who observed algae and fungi in the 1660s. In the 1670s‚ “Anton van Leeuwenhoek‚ a Dutch merchant‚ constructed a number of simple microscopes and observed details of numerous forms of protozoa‚ fungi‚ and bacteria”

As mentioned above‚ bacterial growth rates during the phase of exponential growth‚ under standard nutritional conditions (culture medium‚ temperature‚ pH‚ etc.)‚ define the bacterium’s generation time. Generation times for bacteria vary from about 12 minutes to 24 hours or more. The generation time for E. coli in the laboratory is 15-20 minutes‚ but in the intestinal tract‚ the coliform’s generation time is estimated to be 12-24 hours. For most known bacteria that can be cultured‚ generation times

Biology was fascinated me tremendously particularly when I was introduced to field of microbiology. I used to wonder how these primitive microbes grow and communicate with each other. Theoretical knowledge of microbiology grabbed my attention and made me curious about these tiny microbes which we cannot be seen through our naked eyes. Therefore I decided to pursue my higher studies and specialisation in microbiology. I started my graduation
