Second week of Microbiology class :)

Hello everyone!
For this week, we continued from the last week's topic. We learnt about the characteristic of algae and virus. The algae's morphology can be identify by its colour. The algae can be found in either brown, green or red in colour. The reason why it's in different colour is because of the pigmentation that occur in the algae itself. For an application in industry, the algae is often used to make colour for shirts, making a dental mold, emulsifier and even as a food source.

Another microorganism is virus which have DNA and RNA. The microorganism have a very small and we have to view it under a special microscope called electron microscope. The virus can reproduce inside the cells of a living host since they cannot grow and multiply by themselves.

We also learnt about the famous scientist in pasteurization. The name given is Louis Pasteur, who was a French biologist, microbiologist and chemist. He discovered the process which is the pasteurization that kills microbes in alcohol such as beer and wine. He stated that the process helps in preventing the alcohol from spoils and became sour since the spoilage factor came from the bacteria in the alcohol. It turns out that pasteurization helps in prolonging the quality of the beverages and the process is also used in dairy products nowadays.

I think the topic on the historical figures in Microbiology is very interesting since we could study and differentiate the old and new process that they have invented. We could also appreciate the discovery that they found for the sake of the future.

That's all for this week. See you next week!

First week of Microbiology class :)

September 17, 2017 Ai 0 Comments

Hello everyone!
I am now officially a freshman in Universiti Putra Malaysia in Serdang and now taking Bachelor Sciences (Honours) Microbiology in Faculty of Biotechnology and Molecular Sciences. This is my first week in class and this blog is especially for BMY3101 Microbiology I subject.

This week, we have our first class with Dr. Wan Zuhainis Saad, which is our lecture for this subject. We had a briefing on what we're going to learn in this subject. Microbiology is specifically a subject that is related to a living things that is called microorganisms and we cannot see it with our naked eyes. This microbe can be found everywhere such as the environment, in our body system, making foods and even decomposing the waste materials.

We have learnt about the general characteristic of Algae, Archaea, Bacteria, Fungi, Protozoa and Virus. These microbes have their own characteristics and morphology. We can identify it by their size, shape and cell activity. Algae, Fungi and Protozoa are belongs to the eukaryotes, whereas Archaea, Bacteria and Virus are belongs to the prokaryotes. These microorganism is applicable in many sector such as agriculture, environment, food, genetic engineering, immunology and medical.

Another extra thing that we learnt is about the largest bacteria in the world that is called Thiomargarita namibiensis. This microbe is called the sulfur pearl of Namibia since it was found in the sea of Namibia. The bacteria needs sulfur to survive and grow as it is from a sulfur granule that is yellowish white in colour.

We also learnt about the history of microbiology. The Father of Microbiologist is Antonie van Leeuwenhoek who is a Dutch businessman and scientist. He discovered the protozoa and called them "animalcules" and contributed in improving the microscopes to view the microorganisms.

Another famous scientist is Edward Jenner, who was an English doctor and he is called the Father of Immunology as he was the pioneer of smallpox vaccination.

That's all for this week class. See you next time!
