Laboratory Exercise #5 Identification of Fungi Fungi‚ like bacteria‚ may be useful in industry but also problematic. Many produce important products including foods‚ chemicals‚ enzymes and pharmaceuticals such as antibiotics and hormones. Molds‚ however‚ in particular‚ are also common contaminants in industry. It is important to be able to recognize and identify them‚ therefore‚ in the laboratory. In today’s laboratory session you will examine some common molds and attempt to identify them.

microorganisms in our planet‚ bacteria. Bacteria lives everywhere‚ in air‚ hot springs‚ and in our bodies. Some bacteria are harmful and some of them are helpful. Biologists use helpful bacteria in several ways. In my essay‚ I will focus on some uses of bacteria in medicine‚ environment‚ and industrial. Bacteria contains many distinctive characteristics that makes it very important for the environment. It is considered one of the basic decomposers in the environment because bacteria analyzes dead organisms

The Ebola Virus History of‚ Occurrences‚ and Effects of Ebola‚ a virus which acquires its name from the Ebola River (located in Zaire‚ Africa)‚ first emerged in September 1976‚ when it erupted simultaneously in 55 villages near the headwaters of the river. It seemed to come out of nowhere‚ and resulted in the deaths of nine out of every ten victims. Although it originated over 20 years ago‚ it still remains as a fear among African citizens‚ where the virus has reappeared occasionally in parts

Having the ability to collect and identify unknown microorganisms is vital in health and medicine. This capability is important for a variety of reasons‚ such as knowing the causative agent of disease‚ knowing if the microorganism obtains any beneficial properties and knowing the correct microorganism to use to create a successful antibiotic. Implementing the experimental methods learned thus far in the microbiology laboratory allowed an unknown bacterium to be identified as a result of this study

lytic cycle where the virus attacks the host‚ injects it its nucleic acid into the host‚ and then spreads throughout the host. They systematically infect the person or animal. Widely known viruses include HIV and Hepatitis B. Bacteria falls under the Monera Kingdom. There are two types of bacteria known at this time. Archaebacteria live in extreme environments that are particularly salty‚ cold‚ and or hot. An example of this would be the bacteria known as thermophile bacteria. They are found at temperatures

Measles Virus In the 1800’s the measles was a very dangerous disease‚ and when people who come in contact with it will die‚ if they have never been exposed to the virus before. The measles is transmitted through the air. The way that the virus is transmitted is that infected droplets are released by coughing‚ sneezing‚ and by talking. When the infected droplets that contain the measles are in the air‚ they are taken into the body through the mouth‚ nose and eyes of the potential person that

Viruses can infect all types of cells including plant‚ animal‚ protozoa‚ fungi‚ and bacteria. Virus composition is unique and does not resemble a living cell because they only contain the necessary parts to enter and leave an infected cell. A virus is a minute parasite (10 to 100 times smaller than bacteria) that is unable to reproduce by itself; however‚ once it infects a vulnerable cell a virus can make the cell’s inner workings produce viruses on its behalf. Viruses typically have either RNA

· Taxonomy ○ Science of classification ○ Provides an orderly basis for the naming of organisms and for placing organisms into a category (taxon) ○ Makes use of and makes sense of the fundamental concepts of unity and diversity among living things ○ Basic principle is that members of higher-levels groups share fewer characteristics than those in lower-level groups * Escherichia coli - rod shape and have a Gram-negative cell wall * Even members of the same species display variations
