Disinfection and sterilization comparison: Microbiology 1 Revision questions

1. Compare and contrast disinfection and sterilization, citing examples of substances of used in the processes. (20 mks)

2. State any ten terminologies used in microbiology and their definitions. (20 mks)

3. Compare and contrast the structure of a fungal cell and bacterial cell. (20 mks)

Bacteria are minuscule single-celled organisms with an incipient nucleus and a limited number of membrane-less cell organelles.

Bacteria come in a variety of shapes, sizes, and colors, and they live in a variety of environments, including dirt, water, and the insides of living organisms.
Bacteria come in a variety of morphologies, such as cocci, bacillus, and spirilla, with cells grouped in chains or clusters.

There are several types of bacteria, some of which are dangerous and others which are innocuous or even useful.
The outermost covering of pathogenic bacteria is called a capsid, and it functions as a protective layer.
Bacteria are classified as Gram-positive or Gram-negative based on staining procedures.
The structural changes in the cell walls of different bacteria cause differences in staining.
Peptidoglycan makes up the cell wall, which protects the cell membrane and other organelles inside.
The cell membrane, which is made up of a phospholipid bilayer and globular proteins, is found inside the cell wall.
A membraneless nucleus and some ribosomes can be found in the cytoplasm. In bacteria, the genetic material is primarily DNA, which is not linked to histone proteins.
In the form of a plasmid, extrachromosomal DNA can also be found in some bacteria.
Binary fission, budding, and fragmentation are used in reproduction, however alternative techniques for transferring genetic elements are accessible, such as transformation, transduction, and conjugation.
Bacteria can be chemoautotrophs (producers), heterotrophs (consumers), or decomposers.

Definition of Fungi
Fungi, singular fungus, are eukaryotes with chitin in their cell walls as a distinguishing feature.

Microscopic species such as molds and yeasts, as well as macroscopic organisms such as mushrooms, are examples of common fungi.
Fungi are heterotrophic organisms that rely on autotrophs for food and energy. These organisms get their nourishment from the environment by secreting digestive enzymes.
Fungi are the ecosystem’s primary decomposers, converting complex organic materials into inorganic chemicals.
Fungi can be free-living or coexist with other creatures in parasitic or symbiotic relationships.
Fungi have an unique nucleus surrounded by a nuclear membrane since they are eukaryotic creatures. The presence of chitin in the cell wall and the absence of chlorophyll distinguishes them from plants.
They also have mitochondria, vesicles, and 80S ribosomes, among other cell organelles.
Most fungi grow in the form of hyphae, which are long elongated thread-like structures that can be septate or aseptate.
Macroscopic fungi can show up in the form of colonies in culture media that vary in size, texture, and color.
In fungus, budding and sporulation are the most common methods of reproduction. Sporulating fungi produce dry spores, which are distributed by the wind or other means.
In fungi that reproduce through spores, sexual reproduction is possible. The haploid spores fuse to form a diploid zygote through cell fusion.
according to Assignment: Disinfection And Sterilization Comparison, Glomeromycota, Ascomycota, Basidiomycota, Chytridiomycota, Blastocladiomycota, and Zygomycota are the six categories of fungi based on the appearance of the spore.
Fungi are important organisms because the majority of them are employed in the pharmaceutical industry to extract antibacterial compounds. Some fungus are also edible and can be utilized as a food source.

4. Describe types of media used in microbiology and how they are prepared. (20 mks)

5. Describe type of stains and their uses in microbiology. (20 mks)

6. Viruses are not living organisms. Discuss.

7. A disadvantage of microorganisms far outweighs their advantages. Discuss. (20 mks)

8. Outline factors that determine distribution of microorganisms in an ecosystem. (20 mks)

9. Explain methods used in cleaning in microbiology laboratory. ( 20 mks)

10. Explain the importance of microbiology.

11. Formulate other questions to help master microbiology 1. (20 mks)



Questions for Discussion (DQ)

Initial responses to the DQ should be at least 250 words long and address all aspects of the questions asked, including at least one scholarly source.
Successful comments are substantive (i.e., they bring something new to the conversation, they engage others in the conversation, and they have a well-developed idea) and contain at least one scholarly source.
Off-topic answers, one- or two-sentence responses, simple affirmations of agreement, or “nice post,” will not be considered substantive. Responses should be at least 150 words long.
I encourage you to include (where appropriate) the readings from the week in your comments.

Participation on a weekly basis

Your initial responses to the obligatory DQ are scored individually and do not count toward participation.
You must post at least one reply to peers (or me) on three distinct days in addition to the DQ responses, for a total of three replies.
A scholarly source/citation is not required for participation posts (unless you cite someone else’s work).
Viewing the weekly announcement and attesting to watching it in the comments is part of your weekly involvement. These announcements are given to ensure that you are aware of all of the tasks that must be completed during the week.

Quality of Writing and APA Format

Familiarize yourself with the APA format and practice correctly applying it. It is utilized for the majority of your degree-related writing projects. For APA paper templates, citation examples, advice, and more, go to the Writing Center in the Student Success Center, which may be found under the Resources option in LoudCloud. Poor use of APA format or the lack of APA format will result in a deduction of points (if required).
Please cite all of your sources! Cite the source whenever possible. A citation is also required when paraphrasing.
I strongly advise you to use the 6th edition of the APA Publication Manual.

Utilization of Direct Quotes

At the Masters’ level, I discourage the use of direct quotes in DQs and assignments and deduct points accordingly.
It is crucial for you to be able to critically assess and comprehend information from journal articles and other sources as Masters’ level students. Simply repeating someone else’s words does not demonstrate comprehension or critical examination of the material.
It is preferable to paraphrase and cite your sources.


Policy of LopesWrite

Before you complete a “final submit” to me for tasks that need to be submitted to LopesWrite, please make sure you have got your report and SI percentage.
Please examine your report after you have got it. This report will highlight any grammatical, punctuation, or spelling mistakes that may be corrected quickly. Instead of being penalized for these errors, take a few extra minutes to review.
Examine your parallels. Did you forget to include a reference? Didn’t you do a good enough job of paraphrasing? Is your paper primarily composed of someone else’s ideas rather than your own?
For advice on boosting your paper and SI score, go to the Writing Center in the Student Success Center, which may be found under the Resources tab in LoudCloud.
