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.
