6th week

Microbiology

During the first lecture of the week, we learned about the external structure of prokaryotes. We managed to study the differences between archaea and bacteria. Other than that, bacteria and archaea can be also classified into two groups which are Gram +ve and Gram -ve. Both of the groups are differ in structures.

Archaea

Bacteria
During the second day of class, we have our first test of microbiology.For me its quite hard because all of the information and facts all mixed up in my head :( I hope that i can score high marks for this test. 


Basic Technique of Microbiology

During the lab session, we moved to a new topic which is the 'Bacterial Staining'. Visualization of microorganisms in the living state is quite difficult because they are minute, transparent and practically colorless when suspended in an aqueous medium. Staining is an auxiliary technique used in microscopy to enhance contrast in the microscopic image. 


We had learned about staining theoretically, and now we managed to carry out practically. during this week lab session, we had done the simple staining that includes the negative staining.

First Class of Second Semester (2nd Week)

Hi peeps! 😊 For our first microbiology class, we were briefed about topics that we are going to learn throughout this second semester generally. And of course, more upcoming projects that we have during this sem. We were divided into new groups and assigned with specific microorganisms for each group. I am in group Fungi 🍄 During the second class of the class, we were given a task to construct a mind map about Microbial Systematic in Fungi. We swapped our mind map with other groups and jotted down things or information that were not stated in the mind map yet. This activity help us to share informations and improved among each other. This semester will be a long and tiring as we have a lot of assignments and lab reports 😪😴  But we will boost up our energy to go through this semester really well and excellenty! 💪

What is microorganism? Microorganism is a small and tiny living things that cant be seen with our naked eyes. Groups of microorganisms During the first week of lecture, we have been introduced to the microbial world. We also learned that not all of the microorganisms are harmful and virulent that can causes diseases, but most of them give benefits in many ways. APPLICATIONS: ⇨Medical ⇨Food ⇨Industrial ⇨Immunology ⇨Agricultural ⇨Genetic ⇨Enviromental ADDITIONAL INFO!
