REFLECTIVE JOURNAL WEEK 4

hello and we meet again!!!
So what had happened in week 4.
Basically, this week we have learned about the energy and carbon source of microrganism. So I have an easiest method on how to remember it. This is my formula:

ENERGY+ELECTRON + CARBON
example : PHOTO- LITHO AUTO- TROPH

 

This week also we have learned the topic about 'Distribution of Microorganisms'. in this topic, one must know the factors  affecting the microbial distribution. 

The physical factors that affecting the distribution of microorganism are:

•  Solutes and Water Activity 
• Temperature 
• Pressure 
• Radiation

Tthe chemical factors that affecting the distribution of microorganism are:

•  pH
• Oxygen Concentration
• Water
• Carbon
• Nitrogen, Phosphorus and Sulfur
• Special Growth Factor
• Trace Elements

In this chapter also one must able  to distinguish the microbes according to the categories.

 

Besides, one must know type of exteremophiles:

In this week, Dr Wan gave ua an activity to be done. it called a crossword game.

This week also I did my own exploring about barophiles. barophiles is the microbes that can live in deep sea. it can withstand pressure under the deep sea.
