E-Portfolio Microbiology II Week 4

Assalam and hi all,

This week Dr Wan taught us of the topic of Aspects of Biotechnology in Microbial Ecology where we learned about the beneficial and harmful effects of microorganisms. Generally, microorganisms can be divided into four types which are:

  • Microbes as Pollutants
  • Microbes as Cause of Pollution
  • Microbes as Indicator of Pollution
  • Microbes may reduce Pollution
Bioremediation 


Process used to treat contaminated media, including water, soil and subsurface material, by altering environmental conditions to stimulate growth of microorganisms and degrade the target pollutants. In many cases, bioremediation is less expensive and more sustainable than other remediation alternatives. Biological treatment is a similar approach used to treat wastes including wastewater, industrial waste and solid waste.

What is up, people! This week, we learned on internal structure and its function of a prokaryote with Dr. Wan Courtesy: https://www.shmoop.com/biology-cells/prokaryotic-cells.html I am actually quiet interested with plasmid, a small structure, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes. Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance. Plasmids have a wide range of lengths, from roughly one thousand DNA base pairs to hundreds of thousands of base pairs. When a bacterium divides, all of the plasmids contained within the cell are copied such that each daughter cell receives a copy of each plasmid. Bacteria can also transfer plasmids to one another through a process called conjugation using sex pili. For our experiment this week, we had done Gram staining and Acid-fast staining....

This week we were given a group task to choose a prokaryote and to make a presentation about the prokaryote. We had chose Serratia marcescens which is  a motile,short rod-shaped, Gram-negative, facultative anaerobe bacterium, classified as an opportunistic pathogen. It was discovered in 1819 by Bartolomeo Bizio in Padua, Italy. Bizio named the genus Serratia in honor of and Italian physicist named Serratia, and chose marcescens for the species name after the Latin word for decay.   S. marcescens was first thought to be harmless (non-pathogenic). Due to its ability to produce red pigmentation, it was first used in 1906 as a marker in order to trace bacterial activity or transmission. It was not until later in the 1950’s that the US government experimented with the S. marcescens and the harmful effects that the bacteria causes were revealed. A study using S. marcescens was carried out to determine the possibility of biological weapons being transmitted by wind current. ...

Assalamualaikum.. Haaaaa.... Apa habaq orang kampungg.. Tudia haa post pertama bagi tahun 2016  Ok, so harini nak share apa yang saya ada belajar tadi dalam masa kurang satu jam tadi bagi subjek AHP2402, Feed Tech So, for today I've learnt about the Characteristics and Nutrient Content of Feedstuffs. These are some synopsis of the things I learnt. Ok, so feedstuffs can be categorized into two categories which is Concentrates and Roughages Concentrates - includes the high energy, low fiber stuffs like grains, oil meals, molasses and dried product. Roughages - includes the high fiber, low energy with lower palatability like hay, staws, silages etc. From these two things, they can be divided into 8 different categories which are, Code Class Description  1 Dry forages and roughages Hay; straw; fodder (aerial part); stover (aerial part without ears, without husks or aerial part without heads); other products with more than 18 percent crude fibre (dry basis...
