E-Portfolio: Microbiology - Week 10

Rise and shine, people!

This week, we learned on Kingdom Protists that consist of:

1. Protozoa - consists of four main group which are Archaezoa, Rhizopoda, Ciliophora and Apicomplexa. These organism, usually single-celled and heterotrophic (using organic carbon as a source of energy), belonging to any of the major lineages of protist and, like most protists, typically microscopic. All protozoans are eukaryotes and therefore possess a “true,” or membrane-bound, nucleus

2. Algae - there are six groups of algae which are Chlorophyta (green algae), Rhodophyta (red algae), Phaeophyta (kelps), Pyrrophyta (dinoflagellates), Crystophyta (diatoms) and Euglenophyta. Algaes can be classified with several characteristics including their reproductive structure, chlorophyll and pigmentations, their storage materials, types of cell wall and others.

3.Slime molds - are a type of protist that aggregates into colonies and ingest bacteria, fungal spores, and possibly other protists. They consists of three main groups which are Myxomycota (plasmodial slime molds), Acrasiomycoyta (cellular slime molds) and Peronosporomycetes (water molds).

This week practical session, we had done experiments on how well the growth of microorganisms on different temperature and pH of the environment.

As you guys know, microorganisms can be classified into mesophilic, thermophilic and psychrophilic according to how well their growth on different temperature of the surrounding.

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...
