Introduction of MICROBIOLOGY (Topic 1)

Assalamualaikum. For this semester I’m taking Microbiology subject. What I’m learning in this course is ALL about bacteria. I think that this course will be fun and interesting because as we all know our life is always surrounded by microorganism that called bacteria and others. In topic 1 for this course is the introduction about microbiology. What I learn in this topic is microbe is a living things that are too small to be seen by our naked eyes. So in order to see and observe them, we need to use microscope which O will learn about microscope in topic 2. Microorganism are also group into 5 categories which is bacteria, fungi, virus, protozoa and algae. We also learn about their characteristics and what are the differences between them that make them different function and benefits with each other. We also learn about how do they divide and their benefits in our lives.

Here are the examples of the microorganism that we had learnt in class.

E.coli bacteria

Protozoa

Algae bloom

Fungus

Lets the history begin!!
History is very important in order for us to know who found out the bacteria and what and how they do the experiment to observe the bacteria. The first observation is by Robert Hooke who is a most famous in his microscopial observation which is his study on thin slice of cork where he describe the microscopic world in his book called “Micrographia”. He also mark the beginning of Cell Theory which is all living things are composed of cell. Then the second scientist is Van Leeuwenhoek who proposed the “Spontaneous Generation”. This theory is proved by John Needham where he done his experiment that agreed with Anton theory. Then Lazzaro disapproved Needham’s theory. Rudolph Virchow then give a new concept called “BIOGENESIS” and says that “Living cells can arise only from its preexisting living cell. Then Pasteur was finally resolved the issue on concept of Spontaneous generation with Biogenesis by doing his own experiment.

this is the Pasteur's experiment where he disapprove the spontaneous generation theory that is proposed by Van Leeuwenhoek based on the theory that I found it is very interesting and important in the cell history

That is what I’ve learn in topic 1. ;)
