Bacteria

1) Describe the basic characteristics of coliform bacteria. As learned in class, Coliforms are a group of bacteria’s’ mostly found in the large intestines of humans and animals. Coliform bacteria can also be found in water and in soul. They are gram-negative bacteria’s, meaning that they have a peptidoglycan layer and another layer of the cell wall. These bacteria are also a rode shape now as bacilli. As we all know or should know by now, gram negative cells have a equine structure to their cell

In this experiment, we wanted to investigate which surfaces in the school had the most bacteria, and we thought that the surfaces used more would have the most bacteria. For this experiment we used agar plates, cotton swabs and distilled water in order to see how much bacteria was on each surface. Cotton swabs were wet with distilled water and then the swabbed ws wied on a 2 inch space of the surface and twisted to cover the entire swab.once we swabbed the surface, we wiped the swab on the plate

Most bacteria are harmless, or essential to life. Bacteria help keep the digestive tract working appropriately in the human body. There are also strands of bacteria that can cause hundreds of illnesses, they can do this in several ways. Bacteria can destroy tissue directly, or reproduce on such a large scale that the body cannot function as it should. Bacteria can rapid produce, dividing into two every twenty minutes if in the correct conditions. They reproduce by binary fission in which the single

The identification of bacteria is important in studies related to diseases. Identifying how bacteria responds to certain biochemical tests can give the experimenter valuable information such as the metabolic activity and morphology of an unknown bacteria. With this information, the scientific community can identify a bacterium and respond appropriately to disease outbreaks This information also helps doctors provide the appropriate diagnosis for patients afflicted with a bacterial disease. The objective

Often in prokaryotes like bacteria, they contain plasmids which are small double stranded rings of extra DNA. Most of these plasmids contain a small amount of genes which replicated by themselves rather than with the DNA in the cell. These plasmids could be beneficial or a detrimental to the bacteria. For the beneficial side, plasmids contain products for toxins that can go on to make their host immune to that of the toxin along with many infectious diseases have been cured by plasmids as antibiotic

There are many types of bacteria. Bacteria are a large group of unicellular microorganisms that have cells walls but lack organelles and an organized nucleus. Some bacteria can cause diseases that are becoming resistant to antibiotics. One of these bacteria is Escherichia coli. If garlic can prevent the growth of E. coli, a special of rod-shaped, facultative anaerobic bacteria in the large intestine of humans and other animals, it might prevent the growth of other bacteria (WebMD, 2010). E. coli

Microscopic single-celled organisms, such as bacteria, consist of a seemingly simple internal structure that lacks membrane-bound organelles, yet bacteria thrive in diverse nutritional environments. The significant ability of bacteria to adapt to a wide variety of nutritional environments reflects their use of overlapping regulatory systems that link gene expression to intracellular accumulation of a small number of key metabolites. Bacteria survive using a diverse array of carbon sources, especially

Microbiology is a study of small living organisms that are hard to be seen without using the microscope; such as bacteria, archaea, viruses, and protozoa. Fungi are different, a majority are big enough for us to see. They’re all have a long history of living on Earth, the scientist also believes they are the first living things that are existing way before mammals or human. Those microorganisms are everywhere around us, some are harmless and some can cause serious diseases. The condition and environment

UNKNOWN 65 Identifying bacteria is beneficial for several reasons. In the food industry, the discovery of bacteria and other microorganisms helped develop processes to prevent food spoilage, such as pasteurization, and bacteria is used to make certain foods, such as cheese, butter, vinegar, and alcohol (1). The discovery of bacteria that break down waste products is beneficial to the waste treatment industry, and the discovery of nitrifying, ammonifying, and nitrogen-fixating bacteria are important for

Glucokinase (glk A) is classified in bacteria based upon having ATP binding site and ROK motif, the sequence of glk A gene (JN645812) of S. aureus ATCC12600 showed presence of ATP binding site and ROK motif. We have earlier observed glk A of S. aureus has higher affinity towards the substrate compared to other bacterial glk A and under anaerobic condition with increased glucose concentration S. aureus exhibited higher rate of biofilm formation. To establish this, 3D structure of glk A was built using
