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!
