Bacteria have been around for about 3. Like all cells, bacteria contain DNA, but the DNA in bacteria is different then other organisms, it's arranged in a single circular chromosome while most cells have several rod shaped chromosomes. Some bacteria also have flagella. This makes the bacteria move by beating in a propeller- motion. Bacteria can be classified in many different ways. There are also bacteria that need oxygen called aerobic bacteria and bacteria that don't need oxygen called anaerobic bacteria. Different bacteria contain different components, While some contain endospores or pili others may contain starch granules or ribosomes and enzymes. Bacteria come in three basic shapes, rod shaped bacteria, which are called bacilli, round shaped bacteria, which are called cocci, and spiral shaped bacteria called spiriochetes. The possibilities are endless, as are the different types of bacteria. Scientists have identified about 30,000 species of bacteria but there must be so many more. Not only this but bacteria can actually fight the diseases they cause. Among with vaccinations bacteria can also create antibiotics that kill the disease after it enters your body. .
Bacteria reproduce by the means of binary fission. In this process the single chromosome is doubled, the bacteria divides into two cells and each cell receives one chromosome. You end up with two new, identical bacteria cells. In transformation, bacteria take up fragments of DNA released into the soil or water from decomposing bacteria. Transduction involves the transfer of DNA between bacteria cells by a bacteriophage. Out of the 30,000 bacteria species discovered, only a few hundred cause diseases yet hundreds of millions have died from bacteria related sickness. Other diseases caused by bacteria include tuberculosis, tetanus, cholera and Lyme disease.

Rod-shaped bacteria looks like abstract art and spiral bacteria looks like DNA strands (Johnson 339). ... Some bacteria break down sugar in foods. Other bacteria feed on organic material, and still other bacteria can feed on industrial wastes. ...
Using cultures to study and identify bacteria has been monumental, as it has given scientists a way to study bacteria independent of their environment. ... These were temporarily named Bacteria A and Bacteria B, respectively. ... After Bacteria A and Bacteria B were isolated, more specific testing could be done to determine their identities. Some of the tests performed were done on both bacteria to collect more general data, while other tests were more specific to each bacteria. ... The same process was repeated for Bacteria B. ...
Drug resistant bacteria has been around for ages. ... Although, when not all the bacteria dies, new strains of bacteria appear that can protect itself from the antibiotics. ... The commonly over-used quote holds true for the bacteria in the WWTP. ... Based on the data, the concentration of bacteria in WWTP is a huge threat to humans because it could potentially spreads its resistant gene to other bacteria (Nachiket). ... Although, bacteria have evolved to decrease their permeability meaning drugs that cannot penetrate the cell walls will have no effect on the bacteria. ...
Bacteria are single celled microbes. ... Most bacteria reproduce by binary fission. ... The economic importance of bacteria derives from the fact that bacteria are exploited by humans in a number of beneficial ways. ... Some bacteria play a helpful role in things like food, milk and cheese. Other bacteria aid in things such as digestion and pest controls. ...
The good bacteria that will be examined is the Lactobacillus acidophilus bacteria. Furthermore, the bad bacteria that will be examined is Staphylococci bacteria. ...
