Unknown bacteria determined to be Alcaligenes faecalis because of its morphological, physiological and metabolic properties. In a laboratory setting, it often becomes necessary to identify an unknown organism. In this experiment, researchers classified an unidentified bacterium based on its physical structure, colony morphology, optimal conditions and metabolic properties. A Gram stain using crystal violet, iodine, and safranin and a simple stain using methylene blue characterized the organism’s

The scientific study of microorganism is known as microbiology. Microorganisms are small living things or organisms that cannot be seen without the use of a microscope. The microorganism can be categorized as eukaryotes for instance plant, animal, protozoa, fungi and they can also be grouped into prokaryotes such as bacteria and archaea. This paper will focus on how to identify an unknown bacterium. Bacteria which is also known as the bacterium is a non-cellular microbe that lacks membrane organelles

The positively best bacteria to receive when doing an unknown project The word bacteria receives a bad connotation in the everyday world but some may not realize the importance bacteria has on a person’s immunity and health. There can be both good and bad bacteria. Good bacteria, for example, helps to breakdown food enabling the digestion process to work smoothly and absorb nutrients like probiotics. These good bacteria are often found in foods like yogurt, cheese, and sauerkraut. Best of

Did this article catch my interest, yes, because it’s talking about how bigger areas of where people live and economies growth of industries and pollution rates are more affected by the bacteria and the difference in the cell biology growth process. Also the difference between the growth processes in one land verses another. This article did hold my interest throughout reading it to the end. I had a hard time at first understanding what they were doing and how. I don’t feel like they explained how

Process and Techniques of Finding Unknown J Abstract: As part of a focal study within Microbiology, many scientists have endeavored to identify the many species and types of microbes found in different environments. In an effort to categorize, understand and distinguish one microbe from another, scientists developed tests to show unique characteristics of microbes. This experiment enlists these tests, such as PCR, Simple and Gram staining, anaerobic growth tests, IMViC, Catalase, Oxidase, selective

Unknown Bacteria Lab Report #21 In Microbiology Lab, we learn the scientific method of streaking, staining, microscopy, aseptic culture, and selective and differential tests. These tests will help me identify my Unknown Bacteria. The first procedure I did was the isolation streak of my unknown out on a Trypticase Soy Agar. The purpose of Trypticase Soy Agar is to provide enough nutrients of the microorganism to grow. After I finish my isolation streak, my plate were incubated and grown. Once

have certain bacteria that are considered good bacteria and therefore treating an infection with a selectively toxic agent would preserve the healthy bacteria in our body. B. Broad spectrum antibiotics are effective in inhibiting growth in a wide variety of both gram-positive and gram-negative bacteria. Such antibiotics are very important when time is limited in determining what kind of bacteria is causing a life-threatening infection. They are also beneficial when the exact bacteria that is causing

uncultured community sample. 16S rRNA genes will distinguish bacteria and represent the microbial diversity of the sampled elliptical. An estimate of the cleanliness of the elliptical will be made based on species-abundance as well as evidence of any pathogenic strains. We will also compare and contrast respective populations of bacteria on clean and disinfected ellipticals to assess disinfectant effectiveness. Methods We collected bacteria from the elliptical, purified and amplified the total community
