Magnetotactic bacteria

Christian Ramirez Bionanotechnology 12/18/14 Review of Magnetotactic Bacteria and Magnetosomes Magnetotactic bacteria are a group of prokaryotes of varying morphologies. The morphologies include coccoid, helical, multicellular, rod-shaped, and vibriod1. Magnetotactic bacteria were first discovered by Salvatore Bellini in 1963 2. The commonality of all members of magnetotactic bacteria is that they passively orient and swim along the geomagnetic field by means of a method called magnetotaxis. The

Magnetotactic bacteria are a group of prokaryotes of varying morphologies. The morphologies include coccoid, helical, multicellular, rod-shaped, and vibriod (Bazylinski 1995). Magnetotactic bacteria were first discovered by Salvatore Bellini in 1963 (Jogler 2009). The commonality of all members of magnetotactic bacteria is that they passively orient and swim along the geomagnetic field by means of a method called magnetotaxis. The ability to swim along the geomagnetic field is made possible by an

light of recent research regarding the use of magnetic heating to eradicate bacteria from surfaces within the human body. People get metal parts implanted all the time to compensate for injuries or very old body parts. These pieces range from metal plates to pins to artificial joints, but they all serve relatively similar purposes—holding bones together. The problem that comes from this from time to time is that bacteria inside a patient’s body eventually find these metal surfaces and seek refuge

The Difficulties of Treating MRSA MRSA is difficult to treat because of it's resistance. Acquired immune processes include the body's adaptive response to antibiotics. ie when given the body makes specific antibodies to combat MRSA by destroying it's outer membrane. Antibiotics can be given orally or through injections. The main antibiotics used are vancomycin and rifampicin and they are most effective when used in combination. If it's used early then it can eradicate

contains only 500-2300 Kba in its genome that produces about 700 different proteins. Its reduced genome has been clearly mapped. M. pneumoniae size range from 0.2 to 0.8 micrometer and are capable of passing through most filters designed to remove bacteria. The bacterium is the smallest living organism capable of replicating itself. The bacterium lacks a cell wall but has a three layered cell membrane with sterols. It can take on any shape from cocci to filamentous. An agar plates the colonies have

different antibiotics on bacteria 2. To develop problem solving and experimental skills, for example, information is accurately processed and presented, experimental procedures are planned, designed and evaluated properly, producing valid results, recording results, and valid conclusion is drawn. 3. To develop the aseptic techniques for preparing agar plates and bacterial culture. Problem statement Do antibiotics have the same effect on killing different types of bacteria? Abstract: The main

Jurassic Park The girl shrieks as the giant tree trunk of a leg crashes down shaking the earth. Her screams are then drowned out by the prehistoric roar of the genetically engineered Tyrannosaurus Rex as it searches for prey (Crichton, 1991). Everyone remembers this scene from the best-selling novel by Michael Crichton, Jurassic Park. These scenes were then brought to life by producer/director Steven Spielberg in the immensely popular movie by the same name

The Effect of Enzymes on Apple Juice Production Biology Period 6 Background Info The purpose of this experiment was to determine which enzyme or the combination of the two enzymes makes the most apple juice from applesauce. We did his by, mixing 10 drops of an enzyme (cellulose/pectinase/both) into a few tablespoons of applesauce. We then left the rest to nature, and watched the liquid funnel out for 10 minutes. Lastly, we recorded our data. The cell wall is a complicated

The Effect of Common Bactericidal Agents on Staphylococcus Epidermidis Introduction Staphylococcus epidermidis is a facultative anaerobic bacterium. It is part of the normal human flora and is found on the skin. Colonies of these bacteria can produce a protective slime called a hydrophobic biofilm. Staphylococcus epidermidis is usually not pathogenic unless it enters the human body. One of the most common places for infections are hospitals where people often have weakened immune systems, open

create a much faster oxidation process. This process usually utilizes higher grade ores compared to heap leaching. This type of bioleaching is characterized by a reactor tank in which relatively finely ground ore and nutrients are added, as well as bacteria containing solution to create a slurry (Figure 1). This mixture is then mechanically or air agitated. [pic] Figure 1: Bioreactor tanks for processing of gold ore Available from: http://wiki.biomine.skelleftea.se/wiki/index.php/Tank_leaching
