Students often ponder upon one particular question: ‘is biology and microbiology the same?’ They are not entirely different, but they are not the same either. It would be safe to say that. Microbiology is a part of biology which involves the intensive study of microorganisms, their living mechanisms, their study of the structure, and so on. Therefore, it brings us to one question, i.e., ‘What is the difference between microbiology and biology?’.
What is Biology?
The word “Biology” is made up of two Greek words- “bios” means life and “logos” means study. Hence, biology is the branch of science which deals with the study of living beings and their vital life processes. Lamarck and Teviranus first coined the term “biology” in the year 1801. Aristotle is known as the Father of Biology. Biology is generally divided into two main branches, i.e., Botany and Zoology. Botany deals with the study of different aspects of plants and Zoology deals with the study of various aspects of animals.
A biologist is a person or a professional who possesses specialised knowledge in the field of Biology.
What is Microbiology?
Microbiology is the branch of biology which deals with the study of microorganisms, like viruses, bacteria, algae, fungi, archaea, and protozoa. These microorganisms are collectively known as microbes. Though the existence of microorganisms was hypothesized for many centuries, Antoni Van Leeuwenhoek (1632-1723) was the first person to observe bacteria and other organisms in water under a homemade single-lens microscope, in the year 1674.
There are mainly two branches of microbiology. They are applied microbiology or biotechnology and pure microbiology. Pure microbiology deals with the profound theoretical study of the organisms as the subject itself. In comparison, applied microbiology or biotechnology deals with the application of microorganisms in specific processes such as brewing or fermentation.
Difference between Biology and Microbiology
|
Biology |
Microbiology |
|
Biology is the branch of science which deals with the study of life and living organisms and their interaction with non living organisms. |
Microbiology is the branch of biology which deals with the study of microorganisms. |
|
Biology deals with both macroscopic and microscopic organisms. |
Microbiology specifically deals with microscopic organisms. |
|
Biologists may or may not use a microscope during biological research as it can be done mostly with naked eyes. |
The use of a microscope is necessary during microbiological research. |
|
Biology is a vast field of science and more diverse. |
Microbiology is a more fundamental and applied science. |
What is Molecular Biology?
Molecular biology is the study of living organisms at a molecular level, and it aims to understand living organisms by examining the components that they are constituted of. It specifically deals with the study of nucleic acids (DNA and RNA) and proteins and their interactions with carbohydrates, lipids, and other biomolecules. It is a specialized branch of biochemistry. Electrophoresis, Polymerase Chain Reaction, Restriction digestion, Litigation, Blotting, Cloning are some of the commonly used molecular biology techniques.

1. Molecular Biology aims to understand living organisms by examining the structure and functions of molecular components that construct them. |
1. Microbiology is the branch of biology which deals with the study of microorganisms. |
|
2. It mainly involves the study of the biological interactions between biomolecules like nucleic acids and proteins in various cell systems. |
2. It mainly involves the study of unicellular, multicellular, and acellular microorganisms like bacteria, viruses, protozoa, algae, archaea, and fungi. |
Did you know?
Anton Van Leeuwenhoek is known as the founding father of microbiology. He discovered microorganisms in the year 1674. He was a cloth trader from Delft, the Dutch Republic who used magnifying glasses to find irregularities in his clothes. Later driven by self-interest, he made a homemade microscope in 1674 and examined a drop of water from the murky Berkelse lake and observed “animalcules” in it, and became the first person to discover microbes. The “animalcules”, as discovered later, were green algae and rotifers. Soon, he found bacteria and red blood cells in 1676. Also, the first recorded microscopic observation was done by Robert Hooke in 1666, when he observed the fruiting body of moulds.
Hence the article clearly explains what are the differences between biology and microbiology. Along with this major difference between molecular biology and microbiology is also discussed in the above article
