The study of microbes, organisms that are too small to be seen with the naked eye is Microbiology. Before emerging as a branch of biology, microbiology enjoyed its applications in human life in the form of fermented foods.

Recent evidence from archaeology suggests that alcoholic beverages from fruits, honey, and rice, were made in Neolithic China as early as 7000 B.C. The principle that makes fermented food, a savouring is, fermentation, the metabolism in microbes. Microbes are also detrimental to humans and other animals as they cause diseases in them.

Thus, microbes remained undisclosed frenemies of human life from the early civilizations.

Important periods in Microbiology:

  • (1665 – 83) - Antoni Von Leeuwenhoek and Robert Koch – aided with Microscopy - Discovery of Microbes.

  • (1857 – 1914) – Emergence of Microbiology as a separate domain in Biology with key scientific discoveries by Louis Pasteur and Robert Koch – Golden Age of Microbiology.

  • (1928 – present)Modern Era of Microbiology - Integration of Microbiology with disciplines Molecular Biology, Recombinant DNA technology and Genetics.

The following are the areas where the celebrated status of integrated Microbiology assumes a pivotal role:

  1. Health Industry: Vaccines, steroids, antibodies, antibiotics, vitamins, probiotics, enzymes, and therapeutics are the major areas where microbiology finds its applications. Studying microbes helps detect, cure, and prevent diseases.

  2. Food and Dairy Industry: Cheese, curd, yogurt, bread, vinegar, butter, fermented beverages, etc, are multi-million industries that rely on microbes.

  3. Agriculture: Microbes decompose and operate the Biogeochemical cycles. They enrich the soil quality. Used as Biofertilizers and Bio-control agents, etc.

  4. Cosmetic Industry: Microbes are the structural and functional hubs for millions of cosmetic products.

  5. Biofuels and Bio-electronics Industry: The metabolism of microbes is amplified to a large-scale level to produce fuels from dead living waste and also biosensors Recent advances are also witnessed in the production of computers.

  6. Water Industry: Wastewater management with microbial cultures ensures the safe release of water into the streams. 

The above key areas are enough to justify the importance of studying Microbiology. Microbiology Assignment Help provides a foundation to help Australian students from the basics to ongoing advanced research topics in Microbiology.

What Topics Come Under Microbiology?

Microbiology includes the study of all the microbes smaller than micrometres.
The various microbes studied under the heading microbiology include:

  • Prokaryotic Microbes: Microbes without a distinct nucleus. Bacteria and Archaea are prokaryotic microbes.

  • Eukaryotic Microbes: Microbes with a distinct nucleus. Protists (algae and protozoa) fungi and helminths. Though helminths are visible to the naked eye, their lifecycle includes inconspicuous eggs and larvae.

  • Acellular Microbes: Not cells but macromolecules, made of Proteins and nucleic acids behave as obligate parasites. Viruses are acellular microbes.

Microbiology is vast and includes the following sub-branches:

  • Pure Microbiology and

  • Applied Microbiology

An advanced topic that our experts made easy for you to understand:
Cell wall in Bacteria: The cell wall in bacteria is the outermost covering, that protects the bacteria from harsh environments. The major component unique to the bacterial cell wall is Peptidoglycan (murein).Structurally murein resembles a meshwork.
Peptidoglycan is also a mesh of glycan chains. Each chain of mesh is made of alternating molecules of NAM (N – Acetyl Muramic acid) and NAG (N – Acetyl Glucosamine).
NAM has 4-5 amino acids linked to it. NAG has no amino acids linked.
 NAM and NAG structure
NAM of one glycan chain crosslinks with NAM of another glycan chain.

There is a difference in the crosslinks of Gram-Negative and Gram-Positive Bacteria.

Gram-Positive Gram-Negative
Chains are crosslinked by pentapeptide Chains are not cross linked

  Cell wall structure in bacteria is of two common types.

Gram-Positive Gram-Negative
Many layers of Peptidoglycan, very thick. Thin layer of Peptidoglycan layer
30-100 nanometres thick 4 nm thick
Teichoic acid chains extend through and beyond the peptidoglycan layer. No Teichoic acid chains.
Cell wall is exterior to the plasma membrane Cell wall is complex and arranged into three layers.
Inner Membrane
Thin layer of peptidoglycan
Outer Membrane

Same name but different strains:
The thing that we most often see in Microbiology is the name of the strain. There are sightings in Microbiology, where we see the same name of species, with slight modifications that accommodate strain names.
For example, E. coli is a species. Species in microbiology include all those strains, which have a common origin and are more similar to each other than they are to any other strains.
At the biological level, E. coli is a reproductive unit and contains many strains.
Strain is a sub-ordinate to sub-species; however, we don’t use the term sub-species for microbes. Sub-species is a concept that includes individuals of a species isolated by geographical boundaries but can breed if the geographical boundaries are removed.
A strain is usually made from a single isolated colony from a pure culture. Strains can be distinguished from the same species by looking at the phenotypic or genotypic characteristics or both. Strains do not remain the same and change due to accumulating mutations.
Recent evidence from Genomics suggests that strains do not differ in Genomes, but they do in Genes. A strain is different from other strains of the same species, is due to the differences in genes between them. The entire genome almost remains the same.
The following are the strains of E. coli:
1.    coli K.12 (Non -pathogenic laboratory strain)
2.    coli O157:H7 (Pathogenic – Cause abdominal cramps and diarrhoea)

  • Viruses, the acellular Microbes:

Viruses are acellular structures. A – without and Cellular – Cell structures.

The following are the reasons for calling viruses as acellular structures.

  1. They do not contain a cell wall

  2. They do not have a cytoplasm.

  3.  No cell organelles.

  4. No respiration

They are just Nucleic acids (DNA or RNA) enclosed in a proteinaceous coat (capsid). Viruses cause a range of diseases in organisms. This makes them sometimes to be called as infectious molecular agents, which is an aspect of non-living things.
The only living feature viruses exhibit is Reproduction. They start reproducing in millions once they enter the living organism. This makes them to be called as Obligate parasites, i.e., they can only be living, inside an organism.
Viruses, thus, lie in between the living and non-living worlds.

  • Shapes of Bacteria:

Bacteria come in different shapes. Though there are plenty of bacteria, all of them could be categorised into a handful of groups, based on common morphology.

Name Description Image
(pl: Cocci)
Round coccus
(pl: Bacilli)
Rod Bacillus
(pl: Vibrios)
Curved Rod vibrio
(pl: Spirilla)
Spiral, rigid, with external flagella Spirillum
(pl: Spirochaetes)
Long, flexible, helical spiral, with internal flagella Spirochaete

FAQ around Microbiology Assignment Help

Microbiology, as the name indicates is the study of the biology of microorganisms. The microbes include Protozoa, Viruses, Algae, Fungi, Bacteria and Archaea. The present status of Microbiology is not limited to biology but is integrated into the various sub-fields of biology, Molecular biology, Immunology, Medicine, and Genetic Engineering.
Harmful microbes trigger environmental disturbances and diseases in living organisms. The scientific term that describes harmful microbes is “Pathogen”.
Probiotics are microbes that are administered in adequate amounts to confer a healthy immune system to a host. Probiotics are proclaimed as “Good Bacteria".
No. A microbiologist is one who is well-versed in all the ongoing research in the field and can carefully handle all the cultures of microbes. He is oriented towards finding solutions that aim towards applications in human contexts. A doctor is one who is graduated from a medical school and is oriented towards curing diseases.
Ans. In microbiology, researchers are exposed to biological hazards in various liquid, tissue samples. These biological hazards can be pathogens or toxins. One should take all the precautionary measures to stay safe in a microbiology lab. Failing to do so would lead to disease or even death.
Antoni Von Leeuwenhoek is proclaimed as the father of Microbiology, because of his pioneering work in disclosing microbial structures to the scientific community. He reported his observations in the form of diagrams. He is also an inspiration to many. From a cloth merchant, with no higher education but only curiosity, he stood as a pioneer of Microbiology.
Mycoplasmas, more commonly known as “Pleuro Pneumonia Like organisms” are the smallest known bacteria.
Until the recent Natural classification of Whittaker, Archaea and bacteria were considered to be the same. However, with the emergence of phylogenetics, the entire life on earth is grouped into three domains Bacteria, Archaea and Eukarya. This system suggests that they all originated from a common ancestor. Phylogenetics also suggests that Archaea and Eukarya are more closely related than bacteria.
Viruses are the smallest microbes. Viruses are one-tenth of a bacterium. 
Life is incomplete without microbes. They are probiotics in our body and food. They operate the biogeochemical cycles and run life as undisclosed engines. They also do affect our health, as many of them are pathogens. Their biology is indeed helping answer many global concerns and uplift mankind in terms of economy and health.
