Bioremediation of Contaminated Soil: Review of Related Literature
Words • 1973
Pages • 8
Bioremediation is defined as use of biological processes to degrade, break down, transform, and/or essentially remove contaminants or impairments of quality from soil and water. Bioremediation is a natural process which relies on bacteria, fungi, and plants to alter contaminants as these organisms carry out their normal life functions. Metabolic processes of these organisms are capable of using chemical contaminants as an energy source, rendering the contaminants harmless or less toxic products in most cases. This paper summarizes the general…...

Exome Sequencing
Words • 1179
Pages • 5
Exome sequencing, also known as whole exome sequencing (WES), is a genomic technique for sequencing the entire protein-coding region of genes in a genome (known as the exome). It consists of two steps: the first step is to select only the subset of DNA that encodes proteins. These regions are known as exons  humans have about 180,000 exons, constituting about 1% of the human genome, or approximately 30 million base pairs. The second step is to sequence the exonic DNA…...
Optimum Growth Temperature for Streptococcus Epidermidis
Words • 873
Pages • 4
Abstract: Often when we heard the word bacteria, we think of it as something bad but in reality, the bacteria can be both positive and negative which can have big impact on our body and environment. Different bacteria have an optimum growth temperature. We wanted to look at staphylococcus epidermidis and find out what it's optimum growth temperatures, so we grew S. epidermidis in three temperature (20 °C, 40 °C, 60°C) which was cold, moderate and extreme. After the data…...

Unicellular organism
Words • 1300
Pages • 6
For prison cell assignment, see Single-celling. Valonia ventricosa is among the largest unicellular species. A unicellular organism, also known as a single-celled organism, is an organism that consists of only one cell, unlike a multicellular organism that consists of multiple cells. Historically the simple single celled organisms have sometimes been referred to as monads. l] The main groups of unicellular organisms are bacteria, archaea, protozoa, unicellular algae and nicellular fungi. Unicellular organisms fall into two general categories: prokaryotic organisms and…...
Formation of Ascospores
Words • 327
Pages • 2
In a typical ascomycotina, pyronema for example, sexual reproduction is by gametangial contact invoving the ascogonium ( female organ) and antherridium (male organ). Ascus and ascopores are results of sexual reproduction . the female and male organs aare produced by the mycelium. A trichogyne is also produced which joins the antheridium to the ascogonium. The content of the antheridium passes into the ascogonium through the trichogyne. The ascogonium and antheridiumare multinucleate. After the contact have pass into the ascogoniu, the…...
The Pandemic Virus

Pages • 2
The virologists determined the identity of the virus causing the disease by taking blood samples from the people who were sick or who were getting sick, the n they put them under the microscope and studied them. They tracked the epidemic down by following where people were getting sick; the virologists finally followed the virus back to the ship that was carrying all the animals and the monkey. They conquered the virus by taking the serum from the host after…...

Phylum Sarcodina
Words • 618
Pages • 3
Sarcodina, the largest phylum (11,500 living species and 33,000 fossil species) of protozoans). It comprises the amebas and related organisms; which are all solitary cells that move and capture food by means of pseudopods, flowing temporary extensions of the cell. Most sarcodines are free living; others are parasitic. One of these parasites is the causative organism of amebic dysentery. With the exception of chloroplasts, sarcodines are identical to the ameboid members of the phylum Chrysophyta. Sarcodines may reproduce asexually by…...

Identify the differences between bacteria, viruses, fungi and parasites Bacteria are a single celled organism that multiplies by themselves. The majority of bacteria’s are harmless and beneficial to the human body but some can cause infectious diseases. A bacterium usually affects one part of the body and doesn’t spread across or through the body. Bacterial infections are normally treated with a cause of antibiotics Viruses are made up of genes and proteins that spread throughout the body by invading the…...
Germs: Bacteria, Viruses, Fungi, and Protozoa
Words • 3035
Pages • 13
A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms, from animals and plants to bacteria and archaea. Characteristics: Like living organisms, viruses contain nucleic acids and proteins. Inside living cells, viruses can reproduce, but not by the process of mitosis like most living cells. Viruses lack some characteristics of living organisms. Outside of living cells, viruses are not alive. Structure/Shape: A virus structure can…...
Antimicrobial Drugs
Words • 1615
Pages • 7
The most common way of alleviating the specific symptoms arrived from diseases is to ingest antimicrobial drugs. Chemotherapeutical antimicrobial agents are chemical compounds intended to inhibit or kill rapidly dividing microorganisms. In order to derive an antimicrobial drug, different chemical compounds must be synthetically formed. Among these specific chemical compounds is a compound famously known as the antibiotic. The antibiotic is classified as an antimicrobial drug because it's a chemical that is produced by either a bacterium or fungus, which…...

Differences between bacteria, viruses, fungi and parasites Bacteria is a microorganism, most bacteria is harmless. It is found in soil, water, plants, animals and humans; it can only be seen under a microscope. Antibiotics can help treat bacterial infections. Examples of bacterial infections are TB and MRSA. Viruses live inside other living organisms. They can enter humans through the nose, mouth and breaks in the skin. Viruses can spread through bodily fluids, the air, and insects such as mosquitos. Antibiotics…...

This experiment was carried out to perform staining methods on microbes, explain the mechanisms of staining, namely, simple staining, and learn how to use the microscope. The experiment setting was kept as sterile as possible when conducting the experiment. The microbes under the microscope were drawn out and labelled. In conclusion, different staining techniques are used to determine the presence of certain exterior structures of the bacteria like the cell envelope or just to identify the basic shape and size…...

There are many reasons for establishing the identity of a microorganism. The reasons range from the knowing the causative agent of a disease in a patient, so as to know how it can be treated, to knowing the correct microorganism to be used for making certain foods or antibiotics. Laboratory scientists are able to isolate, identify, and determine the antimicrobial susceptibility pattern. Some methods that are used in laboratory settings are: the use of microscopy whether it’s using wet mounts…...

Identification of Microorganisms by Differential Staining
Words • 639
Pages • 3
Through the process of differential staining, there are distinct differences between the cell walls of gram-positive and gram-negative bacteria. In the case of gram-positive bacteria, the cell wall is comprised of 60-90% peptidoglycan and is very thick. There are numerous layers of teichoic acid bound with peptidoglycan thereby creating very thick cell membranes which causes the cell wall to take up large quantities of basic dye and appears purple. (Hands-on-Labs. (2012)). Conversely, gram-negative bacteria cell walls are much thinner with…...

Bacteria These are tiny microorganisms, they cannot be seen with the naked eye. They exist on virtually every living thing or object in the environment i.e. dirt, water, caves, trees, dead animals, and within everybody living on earth. Its nutrition is from its surroundings. We carry bacteria in the body, mainly in the intestines, on the genitalia or on the skin. Bacteria can be good or bad. It can help our immune system but there are bad bacteria which make…...
