Reproduction and gene transfer[ change change source ] A bacterium reproduces creates more bacteria by dividing in half and creating two "daughter" cells. Each daughter is identical in shape to the parent, but is smaller. Bacteria do not have sexes, but they do transmit DNA by several kinds of horizontal gene transfer. This is how they share resistance to antibiotics from one strain to another.
Bacteria; Deinococcus-Thermus; Deinococci; Themales; Thermophilus; Aquaticus Species  Description and significance Thermus aquaticus is a typical gram negative bacteria, meaning that its cell walls contain much less peptidoglycan than their gram positive cousins, and unlike gram positive bacteria, gram negative bacteria contain lipoproteins.
Thermus aquaticus appears as either a rod or short filaments, and the rod-shaped cells will tend to form either a rosette or a linear pattern Thermus aquaticus a bacterium species.
When exposed to sunlight, Thermus can exhibit a yellow, pink, or red color due to pigments within the bacteria. Along with the coloration, Thermus aquaticus can either have flagella or be immotile.
Thermus aquaticus has proven to be quite a useful organism in the field of Biotechnology, as its enzyme Taq polymerase is harvested for use in polymerase chain reactions PCR. DNA strains for T. The distinguishing feature of T. III This is what differentiates it from all other thermophiles.
Two studies have demonstrated that T. In any case "coherent circular restriction endonuclease maps have been published for only 4," .
Some of the most common sources for organic material are as follows: The algal-bacterial mat is an area at the surface of a hot springs environment containing decomposing organic matter, and is thought to be a major source of organic compounds for T.
It is also believed that organic matter is present in the runoff of the surrounding soil . Thermus aquaticus belongs to the Deinococcus-Thermus group. It is one of the first hyperthermophilic organisms to be discovered.
It has a three layered membrane composed of an inner plasma membrane, an intermediate and a rougher outer layer. Along the inner membrane usually lies a series of rod like structures that resemble individual cells, which are called rotund bodies.
These cell like structures are the most unique characteristic of Thermus aquaticus. The rest of its anatomy is just like other bacteria.
However, there are no flagella or cilia present in Thermus aquaticus, suggesting that this bacterium is immotile . The life-cycle of this bacteria is just like the life-cycles of other bacteria.
Ecology including pathogenesis The temperature of an environment can be considered one of the most influencial factors in determining the composition of the specific ecosystem.
For example geothermal springs have a very high temperature range, and, as a result, the organisms that live there must be able to cope with such conditions. Thermus aquaticus was first found in several of the Yellowstone National Park hot springs. It can survive at temperatures of degrees Celsius in weakly acidic to alkaline pH waters.
It was also discovered in marine thermal springs, low saline solfataric springs and thermally polluted waters. The ideal conditions for this organism to grow are around 70 to 75 degrees Celsius at a pH of 7.
There are also some other environmental factors to consider, such as: Since these organisms exist at high temperatures, there is only a small amount of dissolved oxygen in the water.
Because of this it is assumed that Thermus can use nitrate as their terminal electron acceptor instead of oxygen. It seems as though high concentrations of sulfide do not greatly affect the number of organisms. The degree of salinity does seem to affect them though.
While there are some strains of Thermus that are halotolerant, there are none that are halophillic, and T. Its growth is inhibited even if there is a 0. Interesting feature The enzyme Taq polymerase is found in the bacterial species Thermus aquaticus.Thermus aquaticus is a typical gram negative bacteria, meaning that its cell walls contain much less peptidoglycan than their gram positive cousins, and unlike gram positive bacteria, gram negative bacteria contain lipoproteins.
Thermus Aquaticus In any case, one of the most famous strains of thermophilic bacteria actually belongs to a species known as Thermus aquaticus, not Strain This species of bacteria is super famous for being the original source of something known as Taq polymerase, a heat stable DNA polymerase, or enzyme that synthesizes DNA.
The Discovery of Thermus aquaticus. On April 1, , Thomas D. Brock and Hudson Freeze published their discovery and cultivation methods of a new species of thermophilic bacteria, which they named Thermus aquaticus..
Extremophile Bacteria. Thermus aquaticus is a species of bacterium that can live in high temperatures, ths species is one of thermophilic bacteria that belong to the Deinococcus-Thermus group.
Thermus aquaticus appears as either a rod or a short slender thread, and the rod-shaped cells will tend to form either a rose shape or a straight line pattern.
