Bacteria

Streptococcus pneumoniae is a type of aerobic bacteria. It is found in the upper region of the pharynx, known as the nasopharynx. It usually does not cause any symptoms in healthy people, but can affect those with a compromised immune system.

Pseudomonas aeruginosa is a gram-negative bacterium. It appears pink or red in the Gram stain due to the structure of its cell wall, which does not retain the crystal violet stain in the Gram staining process.

Harmful bacteria that cause infections can come from many sources including soil, freshwater, seawater, animals, other people or fomites. They can gain access to our bodies in many ways including open wounds, ingestion, sexual intercourse, blood transfer, inhalation or direct contact on skin/mucous membranes.

C. Difficile is a species of bacteria. Its full name is Clostridium Difficile. This bug is responsible for a lot of hospital acquired gastrointestinal infections(usually diarrheal infections that can range from mild to bloody and very painful). C. Diff infections often occur in patients who are on strong antibiotics that kill off the normal flora of the gut (the regular bacteria that live in your small intestine/colon and help to digest/defend from other infections). A complication of a c. diff infection is pseudomembranous colitis, a condition where a membrane forms over the lumen(inner lining) of the colon. Treatment for c. diff includes stopping the antibiotics that killed off the normal flora, and adding antibiotics such as metronidazole or vancomycin which are good at killing of c. diff.

The bacteria in the intestines is beneficial. Acidophillus bacteria as in Yogurt is also beneficial .

Lactobacillus is used commercially in dairy industry widely.

Escherichia coli, an intestinal bacteria helps in digestion and absorption of food . Staphylococcus aurous, a bacteria present on our skin, aids it in immunity. It prevents the invasion of foreign microorganisms by releasing certain toxins.

Eubacteria are a diverse group of bacteria that play important roles in nutrient recycling, decomposition, nitrogen fixation, and some forms of fermentation. They can also be harmful pathogens causing diseases in humans, animals, and plants.

Yes, bacteria have a cell wall. It helps to maintain their shape and provides protection from the external environment. The cell wall of bacteria is made of peptidoglycan.

There are 3 Main Things: Moisture, Warmth, and a source of food

some good things about bacteria is that bacteria may get you sick but bacteria is also what some people use in medicines that can cure what you might have from bacteria for example bacteria is used in germ-x and hand sanitizers so when you get bacteria and you go to take care of it your just getting good bacteria to kill the bad bacteria it's like a war.

Chemosynthetic bacteria means bacteria that can make chemical things (synthetic). Basically any bacteria are chemosynthetic - they all product different chemicals as part of their metabolism. There are methanogens that produce methane gas, there are photosynthetic organisms that produce oxygen (like plants, and the ancestry of plants), others can produce nitrogen gas, like those bacteria that live in nodules on legume plants. Other bacteria can produce acids from fermentation like proprionic acid which gives Swiss cheese its nutty flavor. So lots and lots of bacteria are chemosynthetic. It just depends on what you want to produce.

Thermophile bacteria thrive at higher temperatures, between 45 and 80 °C and some even higher than that (hyperthermophile). No limit is known, and new species are discovered, but at 150°C the DNA is destroyed, so any imaginary bacteria that could resisting such temperature must have an unknown constitution. A variety of bacterialike Pyrolobus fumarii is found to reproduce at 121 °C and survive until 130 °C. Some genuine bacteria resist temperature above 100°C, and 121°C is needed to kill Clostridium botulinum.

Some do some don't. Plants that grow near the equator experience very little change in seasons and do just fine. While many deciduos trees in higher lattitudes cannot survive without a change in season.

Thermophiles like temperatures above 45 °C. The bacterialike Pyrolobus fumarii likes heat above 110°C and Strain 121 is found to reproduce at 121 °C and survive until 130 °C. Some genuine bacteria resist temperature above 100°C, and 121°C is needed to kill Clostridium botulinum. At 150°C the DNA is destroyed, so any imaginary bacteria that could resisting such temperature must have an unknown constitution. So, 45 to 100°C is the temperature that the thermophile bacteria like.

Previous answer:

Well one person says 800 degrees celsius, the other says 200, and the other says 500 degrees. I have done some amateur research and my guess is anywhere from 100 degrees to 800. It really depends on what bacteria it is! This web site:

Says that Heat-loving bacteria flourish at temperatures at and above the boiling point of water, which leads me to believe that they can live in any water that is above 100 degrees celsius.

Food and chemicals

There are two kingdoms of bacteria. The two kingdoms of bacteria are Archaebacteria and Eubacteria. This is taught in biology.

If the counter is left unclean for the same lengthof time as the toilet the counter which is most commonly used more then the toilet will harvest more bacteria. If one is preparing chicken or some kind of meat and some is left on the counter that sample will cultivate millions of colonies and spread it throughout the table.

Pili or fimbriae are hair-like structures on the surface of bacteria that can help with adherence to surfaces or other cells. Some bacteria can also move using a gliding mechanism, which does not involve flagella but rather a smooth movement across a surface. Additionally, some bacteria can move using structures called axial filaments or periplasmic flagella.

They can wiggle and squirm around like worms, make use of liquid to move from one point to another; most have flagella around their cell walls which help them move around. The flagella can be very short and populous all around the outside of their "skin," or one big "tail" that acts as a rudder to steer them around.

Bacteria can grow almost anywhere that provides them with enough moisture, nutrients, and a suitable temperature. Common places where bacteria grow include soil, water, and various surfaces like countertops, skin, and within the human body. Depending on the species, bacteria can thrive in a wide range of environments, from extreme heat to cold temperatures.

Despite their relative simplicity, bacteria carry out most of the key chemical changes of carbon, nitrogen, and sulfur in the living world. The eukaryotes, like us humans, perform relatively small changes to their molecules. Benefits of bacteria include: * Bacteria are the only living things which can fix nitrogen. They are therefore essential to all other life on Earth. * Some plants such as beans keep nitrogen fixing bacteria as symbionts in nodules on their root. * Bacteria are the major decomposers of dead plants and animals, so freeing their atoms to be re-used by other living things. * Cows and other animals keep bacteria in their stomachs, as only bacteria can break down the tough cell walls of plants. * People use bacteria to turn wine into vinegar and milk into cheese and yogurt. * They are increasingly used in biotechnology to manufacture proteins.

Bacteria form and reproduce in most cases in warm, moist sugar and organic matter rich environments. Bacteria growth is most effective in temperatures similar to body temperature and where oxygen is present. A neutral Ph is also effective for bacteria growth.

Bacteria range in size, but all are microscopic. They cannot be seen by the unaided, naked human eye. They are measured in micrometers; usually a decimal placed answer.... Many are super small

In the early development of human life on earth, three important steps that were taken are as follows: First, the development of tools enabled human beings more effective control over their environments. Second, the formation of a recognizable and intentional social and political structure served as a powerful stabilizing force for humankind. Third, agriculture provided still more stability for human societies while also ensuring (to a great, if not complete, extent) future growth and additional civilizational developments.
