Sad Kid



Microorganisms are small yet they are virtually all around us, on us, and in us, affecting every aspect of our lives. This is why microbiology is a very important branch of science – it gives us insight about these minute organisms that holds all the important processes of life.

To say that microbiology is simply the study of microbes is a grave injustice to these invisible organisms. Scientists know that microorganisms hold the key to the existence of life on Earth and studying just one facet is not helpful to humankind at all. More so, there are trillions of microorganisms in existence in our planet.

Some of the sub disciplines of microbiology include bacteriology, evolutionary microbiology, environmental microbiology, industrial microbiology, clinical or medical microbiology, food microbiology, mycology, microbial genetics, microbial physiology, veterinary microbiology, and virology.


According to scientists, there are 5 million trillion trillion of microbial cells in existence in our planet. That number is not a typo error nor is it a joke. The human body alone has more bacteria than cells. Specifically, there are 40 trillion microbes compared to 30 trillion cells in the body. Most of these microorganisms live inside the digestive tract.

The figures are mind blowing making you wonder whether all of these microbes are all important. The answer is a resounding “YES”! Below are some ways how important these microorganisms are.

Microscopic Technology
    • Fighting diseases:

Microbiology has enables scientists to develop vaccines and antibiotics to combat the world’s deadliest diseases.

    • Biotechnology:

Microbiology the heart of genetic engineering, the whole process of which is hosted by bacteria.

    • Agriculture:

By studying microbes, farmers are able to improve nitrate levels and increase output.

    • Environment:

Bacteria play an important role in keeping the oxygen and carbon dioxide levels balanced.

    • Chemical Products:

Microbes are utilized to create different types of products that are useful in everyday life.


With a myriad of uses and lots of sub disciplines to choose from, learning microbiology definitely holds a lot of rewards scientifically and financially. According to Payscale, the median salary of a microbiologist is around $52K per year, making it one of the most sought after jobs.

A career in microbiology is not limited to research labs alone. This is also useful in ecology and forensic science.

Those who have plans of learning microbiology or pursuing a career in it can just earn an Associate Degree in a technical college in order to work as a microbiology technician. However, earning a Bachelor’s Degree to a Doctoral Degree opens up more opportunities not to mention higher financial rewards.

Micro Biology Research


Microbiology is lagging behind its cousin when it comes to automation and robotics. In the past, it seems impossible to automate microbiological processes since it handles the smallest and most sensitive organisms.

However, with the advancement of technology, there are now microbiology labs that are totally automated. Automation has improved turnaround time and reduced labor costs. It has also enabled scientists to culture microbes much faster.


Since automation is in its early stages in microbiology, new features to the automation system are expected. As microbiology embraces new technology, more scientists in this field and its sub disciplines are needed.
