During today's Microbiology class, Dr showed us some of the videos that we made. I'm glad mine didn't get picked to be played in the class. I'M GLAD! Hahaha. Our class started with Dr telling us to download and register several apps and websites. There are about 2 to 3 websites that we have to register. And that actually took about one hour. (⊙.⊙)
The lesson went on with Dr teaching us our very first lesson, talking about the functions of microbes. And she told us about bacteria that live in cheese will make different holes on cheese. I don't know why but that information really caught my attention and I kept on replaying that line in my mind throughout the class, even after the class has ended LOL. I will Google it later, I guess, I hope. Hehe.
And, today my table line was asked by Dr to tell her the four roles of microbes but the person at the end of my table wasn't able to answer her quickly, and she moved the question to the table in front of us. Haha. I must say, I was glad because I really did not know the answer. I mean, I still didn't get the idea yet.
At the end of the class, she told us to take out a piece of paper and wrote down our names and matrics numbers. "A quiz?" Was what I thought but it's not. She told us to write down the words that we remembered the most for today's lesson in 2 minutes. I managed to wrote down the cheese and bacteria will form different holes part LOL. At first that was the only thing that i remembered but few seconds passed by, i remembered the other stuff too. And also the words "sewage" "digestion" "medicine" referring to the functions of microbes.
After that, she asked us to wrote down the "muddiest point" which means the points from what she told us during today's lesson that we didn't understand the most. Hmmm honestly I still managed to understand what Dr was teaching, but I still am not familiar or ever heard of the names of the microbes and I couldn't hear what the names of some of the microbes well.
Afterwards, we handed out our papers and she reads some of them. And she read one of my classmate's paper saying that they are not familiar yet with the names of the microbes. Dr said of course we are not familiar yet with the names! Hehe. I'm a little glad that there are people that are in the same boat, hehe. And that is not good. Not good at all. Because I should aim to be among the best! (҂⌣̀_⌣́) I have to read more, more, more~
And I just know today that this is a diatom and diatom is an algae.

| So prettyyyy. This is my first time seeing a diatom. (・◇・) |
And next, like I told you earlier. (The part where I am most interested in during today's lesson) That different bacteria form different holes on cheese. And I did some Google-ing on that. There are three bacteria that are used to make cheese (but from what I searched, it was specifically the bacteria used to make Swiss cheese) : Streptococcus thermophillus, Lactobacillus helveticus and Propionibacterium shermanii. Streptoccus thermophillus and Lactobacillus helveticus function mainly on producing lactic acid. The lactic acid produced will be consumed by Propionibacterium shermanii which as a byproduct from consuming the lactic acid, it will produce acetate, propionic acid and carbon dioxide. The acetate and propionic acid will give the cheese its distinct flavour while the carbon dioxide will forms bubbles within the cheese. These carbon dioxide bubbles are left in the cheese as it continues to ferment, thus will give the Swiss cheese its holes. You can read about it more from this link :D http://www.todayifoundout.com/index.php/2010/11/why-swiss-cheese-has-holes-in-it/
And lastly, the summary of my lesson for today, a bit of this and that since Dr mentioned few examples of microbes with their functions in our daily life. ( ͡° ͜ʖ ͡°)
