anaerobic bacteria. 1. Degradative mechanism Anaerobic bioremediation is a remediation technique which injects organics, which become electron donors, together with nutrient salts such as nitrogen and phosphorus into groundwater and degrades contaminants by anaerobic bacteria. It is known that PCE and TCE are dechlorinated reductively by anaerobic bacteria and degraded into dichloroethylene (DCE), vinyl chloride (VC), ethylene and likewise, ethane (Fig. 1). Various types of anaerobic bacteria can

For example, the name of the bacteria, virus, or parasite.[pic] There are several types of Hepatitis. Infectious hepatitis, which is commonly referred to as Hepatitis A, infects the liver via the virus of the same name. This is commonly spread through contamination from feces. The virus is transmitted among people through direct contact

Simple organisms-unicellular Complex organisms-multicellular The cell was discovered by Reginald Hooke in between 1635-1703 • He used a slice cork under the microscope to discover and saw empty spaces, which he called cells Cells are the basic unit of life. • For any structure to be called a cell it will have to have 3 or 4 basic features o (animal) round, plasma membrane (outside), nucleus (middle of the cell), cytoplasm (in btwn the nucleus and the plasma membrane) have 3 components

ABSTRACT Microorganisms are too small to be seen with the unaided eye, therefore, they must be observed with a microscope. Due to the fast innovations and advances in microscopy, we are now capable of examining, determining and observing them. This experiment, which utilized the hay infusion as the residing area of microorganisms, investigated the living organism in a drop of water, their manifestation of the different attributes in life. During the run of the experiment, paramecium and specie

• What is the infectious agent (pathogen) that causes this infectious disease? For example, the name of the bacteria, virus, or parasite. The infectious agent I choose is the Norovirus. The Norovirus is a small virus that is highly contagious. The Norovirus is also the most common cause of gastroenteritis. Gastroenteritis is often referred to as the stomach flu. Gastroenteritis is the inflammation of gastrointestinal tract. This includes the stomach and intestines. The inflammation usually

INTRODUCTION There are many reasons for knowing the identity of microorganisms. 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. This study was done by applying all the methods that have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium.

The simplest carbohydrates are monosaccharides, e.g. glucose (C 6H12O6), and are monomers. 3. Monosaccharides can join together to form disaccharides in a condensation reaction, forming a glycosidic bond. This can be broken by hydrolysis: 4. Polysaccharides are formed from multiple glycosidic bonds, and include starch

produce new cells. The bacteria excel between the temperatures 40*-140*F also known as the “danger zone.” This supports the idea that the bacteria cannot grow at refrigerator or freezer temperatures. History: this is one of the most common causes of food poisoning in the word. Some researchers say the bacteria causes nearly one million sicknesses each year. This infection often occurs when foods are kept in large quantities and left out for a while before serving. This bacteria therefore effects

Cloning DNA cloning has given major insights into understanding the genetic makeup of an organism. The cloning process will allow the alteration of DNA to better the organism in ways like nutritional value or resistance to diseases. DNA cloning has opened new doors to the studies of genetics. In order to clone DNA, there is a specific method in which selective amplifying is required of DNA sequences, which would in turn generate homogenous DNA populations (Strachan & Read, Chapter Chapter 4
