Bacteria

Bacteria eat the parts of the food in the large intestine that are edible to them and they release bi-products when they digest it, specifically gases. These bacteria also produce B complex vitamins and vitamin K.

No, bacteria must have certain things to survive such as food and a certain temperature, which would explain why boiling water purifies it of bacteria; most bacteria can't survive it. Also, bacteria can't grow in some deserts nor at the North and South poles; not enough food, awful temperatures. But...bacteria is very resourceful stuff, and you can find one species of it or another surviving *almost* anywhere.

Filtration methods like reverse osmosis or activated carbon filters are effective at removing particles and impurities from water but they may not necessarily kill bacteria. Ultraviolet (UV) light or ozone treatment are disinfection methods that can kill bacteria without using chemicals.

Bacterial capsules are composed of high-molecular-weight polysaccharides and/or polypeptides, and are associated with virulence and biofilm formation. Unfortunately, capsules do not stain well with crystal violet, methylene blue, or other simple stains. This unit describes two methods of capsule staining. The first is a wet-mount method using India ink; the capsule is visualized as a refractile zone surrounding a cell. The second is a direct-staining dry-mount method that precipitates copper sulfate and leaves the capsule as a pale blue zone. Both methods are easily performed within approximately 5 min.

No, bacteria and parasites are different types of organisms. Bacteria are single-celled microorganisms that can be beneficial or harmful, while parasites are organisms that live on or inside another organism (the host) and rely on the host for nutrients and shelter. Parasites can be bacteria, but not all bacteria are parasites.

Yes, some bacteria possess enzymes that can break down cellulose into simpler sugar molecules through a process called cellulolysis. These bacteria play an essential role in the decomposition of plant material in the environment.

Pasteurizat­ion is a compromise. If you boil a food, you can kill all bacteria and make the food sterile, but you often significantly affect the taste and nutritional value of the food. When you pasteurize a food (almost always a liquid), what you are doing is heating it to a high enough temperature to kill certain (but not all) bacteria and to disable certain enzymes, and in return you are minimizing the effects on taste as much as you can. Milk can be pasteurized by heating to 145 degrees F (62.8 degrees C) for half an hour or 163 degrees F (72.8 degrees C) for 15 seconds.

Bacteria can thrive in a wide range of environments, from hot springs to ice-cold waters, and from acidic to alkaline conditions. Some bacteria prefer environments with abundant nutrients, while others can survive in extreme conditions such as high salt concentrations or low oxygen levels. Overall, bacteria are highly adaptive and can be found in almost every possible habitat on Earth.

Yes Bacteria is everywhere. There is Bacteria in your bed, seat, on your TV and even in your mouth! So if you worry about being harmed from touching Bacteria, you actually aren't scared, because it is everywhere and you are always touching Bacteria. I hope that answered your question.

Common media used to determine motility and growth patterns of bacteria include agar-based media such as nutrient agar, motility agar, or semisolid agar. These media allow for observing colony morphology, motility (through diffusion in semisolid agar), and growth patterns (e.g., pellicle formation). Additionally, specialized media like SIM (sulfide-indole-motility) agar can be used to detect hydrogen sulfide production, indole production, and motility of specific bacteria.

Bacteria are single-celled organisms that can reproduce independently, while viruses are not cells and require a host cell to replicate. Bacteria are larger and can be treated with antibiotics, whereas viruses are much smaller and are typically treated with antiviral medications.

Between 63 degrees and 37 degrees Fahrenheit, most bacteria will either become inactive or grow at a slower rate. The growth of bacteria is significantly reduced at lower temperatures, helping to prevent spoilage and foodborne illnesses. Refrigeration at temperatures below 40 degrees Fahrenheit is commonly used to slow bacterial growth and preserve food.

Yes, Serratia marcescens typically tests negative for citrate utilization in citrate utilization tests. This bacterium lacks the enzyme citrate-permease needed to import citrate into the cell, resulting in a negative citrate test.

Extra chromosomal DNA - plasmids- are useful to bacteria as they possess favourable genes conferring resistance to certain toxins/antibiotics and/or assist with the survival of the bacteria through metabolic benefits. The extra chromosomal DNA is only maintained if it has a purpose so a plasmid conferring antibiotic resistance will not be maintained by a bacterium in an antibiotic free environment...

Cryptosporidium is not a bacteria; it is a protozoan parasite. It can cause gastrointestinal illness in humans and animals through contaminated food or water sources.

It's neither.. its considered apart of the protist kingdom. Fungi have their own kingdom as does bacteria, animals, archaea and plants.

Plants, Animals, Fungi and Protists are all called Eukaryotes because they all are similar in that they all have a nucleus and things called "membrane bound organelles". They are generally considered more complex then Archaea and Bacteria.

The amazing thing about Eukaryotes is that originally they were once bacteria as well. However millions of years ago a bacteria engulfed another bacteria which kept living inside the other bacteria and released nutrients from inside the bacteria which actually helped it survive. That original bacteria turned into the "membrane bound organelles" we find in eukaryotes today!!!!!! The nucleus of the eukaryotes (which bacteria and archaea dont have) may have arisen from an engulfed virus but we still dont know if that is correct. :S

Some Protists can cause infection while most don't.

The medical term for a highly contagious bacterial skin infection characterized by skin pus is "impetigo." It is commonly caused by Staphylococcus aureus or Streptococcus pyogenes bacteria and is more common in children. Treatment typically involves antibiotics and keeping the affected area clean.

Typhoid or Typhoid fever is an infection that causes diarrhea and a rash -- most commonly due to a type of bacteria called Salmonella typhi.

Sometimes confused with Typhus, which is caused by one of two types of bacteria: Rickettsia typhi or Rickettsia prowazekii.

Many ancient phototrophic and heterotrophic bacteria that lived in colonial associations are known as cyanobacteria. These bacteria played a crucial role in shaping Earth's early environment through oxygen production and carbon fixation. Collectively, they are sometimes referred to as blue-green algae due to their photosynthetic capabilities.

One way to plan an experiment would be to introduce a known amount of bacteria near the pollen grains and observe if there is movement of the pollen grains. A control group without bacteria could also be set up for comparison. Additionally, samples could be taken at different time points to track the movement of pollen grains and determine if it correlates with the presence of bacteria.

Streptococcus pyogenes, also known as Group A Streptococcus, is the bacterial organism responsible for causing rheumatic fever.

viruses are a type of microbe, although they are not meant to be referred to that term because they do not exceed all the seven life processes

A halophile would be an organism that thrives in (or requires a) very salty environments. A halotolerant organism would be able to survive in a salty enviroment, but can also live outside of this environment.
