What is the name of the excretory product of bacteria?

Bacteria excrete many things depending on which biological process is being carried out. Such things include but are not limited to carbon dioxide, various toxins, proteins engineered into their genomes if there are any, and substances used in population control and quorum sensing. As far as I know there isn't one specific term to cover all of that, even if you limit to just the waste products. You may wish to narrow your search a little bit.

What is it called when feces are placed in a growth medium for bacterial analysis?

This process is called fecal culture or stool culture, where feces are placed in a specific growth medium to allow bacteria to grow and be identified.

What is the name of the bacteria in the leguminous plants?

The bacteria in leguminous plants that form a symbiotic relationship with the plant are called rhizobia. These bacteria help the plant fix nitrogen from the air into a form that can be used by the plant for growth, and in return, the plant provides sugars to the bacteria.

What common illnesses and infections are caused by bacteria virusus fungi and parasites?

Bacterial infections: strep throat, urinary tract infections Viral infections: common cold, flu Fungal infections: athlete's foot, yeast infections Parasitic infections: malaria, giardiasis

How does bacteria relate to science concepts?

Bacteria are a fundamental part of many scientific concepts such as microbiology, ecology, and molecular biology. They are used in research to understand basic biological processes, study diseases, and develop new applications in biotechnology. Bacteria play a crucial role in nutrient cycling, food production, and disease prevention, making them a key focus in various branches of science.

Are bacteria that cause diseases such as syphilis or cholera?

Yes, bacteria such as Treponema pallidum (causes syphilis) and Vibrio cholerae (causes cholera) can cause infectious diseases in humans. These bacteria enter the body through various routes and can lead to a range of symptoms and complications if not treated promptly.

How do you stop compulsive hand washing?

To stop compulsive hand washing, it's important to seek help from a mental health professional who can provide therapy, such as cognitive-behavioral therapy (CBT), to address the underlying anxiety and obsessive thoughts driving the behavior. Additionally, practicing mindfulness techniques and gradually reducing the frequency of hand washing can also be helpful in overcoming the compulsion.

At an old gas station gasoline leaks from an underground storage link is this Toxic sediment nutrient or bacterial pollution?

Gasoline leaking from an underground storage tank at an old gas station is considered toxic pollution. Gasoline contains harmful chemicals such as benzene, toluene, and xylene, which can contaminate soil, water, and air, posing health risks to humans and wildlife. Cleaning up and containing gasoline leaks is essential to prevent further environmental damage.

Does 0 degrees celsius kill bacteria?

No, 0 degrees Celsius does not kill bacteria. It can slow down their growth and reproduction, but many bacteria are capable of surviving freezing temperatures and can remain dormant until conditions are more favorable for growth.

What general type of stain is used to separate types of bacteria based on their cellular structures?

Gram staining is a general type of stain used to separate types of bacteria based on their cellular structures. This technique classifies bacteria into Gram-positive (purple) and Gram-negative (pink) based on differences in their cell wall composition.

What is the color of phaeophytin?

Pheophytin or phaeophytin (abbreviated Pheo) is a chemical compound that serves as the firstelectron carrier intermediate in the electron transfer pathway of photosystem II (PS II) inplants, and the photosynthetic reaction center (RC P870) found in purple bacteria. In both PS II and RC P870, light drives electrons from the reaction center through pheophytin, which then passes the electrons to a quinone (QA) in RC P870 and RC P680. The overall mechanisms, roles, and purposes of the pheophytin molecules in the two transport chains are analogous to each other.

What is the scientific name for proteobacteria?

The scientific name for Protococcus is Protococcus viridius Agardh. The classification of protoccocus is: Plantae, Viridaeplantae, chlorophyta, clorophytina, trebouxiophyceae, chlorellales, ctenocladaceae.

Is the tsetse fly born with the bacteria it carries?

No it is not it gets it from a special type of plant or the animals it bites into.

What is Parvo Bacteria?

Parvobacterium are small, gram negative coccobacilli. they require blood or blood products for their growth in vitro.

the genera include,

  1. Haemophilus
  2. Bordetella
  3. Brucella
  4. Pasteurella
  5. Franciscella
  6. Actinobacillus
  7. Gardnerella

How can bacteriophage contribute to the host genome?

Scientists had already reached the milestone of fully sequencing their first genome that of the FX174 bacteriophage, whose 5,375 nucleotides had been determined in 1977 (Sanger et al., [ 1977b) but this endeavor proved much easier than sequencing the genomes of more complex life forms. Indeed, the prospect of sequencing the 1 million base pairs of the E. coli genome or the 3 billion nucleotides of the human genome seemed close to impossible. ..............

Will bleach kill cyanobacteria?

Yes, bleach can be effective in killing cyanobacteria. However, caution should be exercised as bleach can also harm aquatic life and disrupt the balance of the ecosystem. It is recommended to use alternative methods to control cyanobacteria growth in natural bodies of water.

Which bacteria on exposures to desiccation experience least likely water loss?

Bacteria that produce endospores, such as Bacillus and Clostridium species, are able to survive desiccation with minimal water loss. These endospores are highly resistant structures that protect the bacterial genome from environmental stresses like desiccation.

What are round or spherical arranged in clusters?

Bacteria that are round are called cocci. Those in strings like a strand of pearls are called streptococci. Those in clusters are called staphylococci.

Why can't you take all of your antibiotics at once?

Because it doesn't work that way. The bacteria and stuff may be scattered through the body, or it is in different stages of development. The medication has to stay in the body long enough to make sure everything is completely killed.

Here is an example of why this might be the case. What if the stuff only renders the bacteria unable to reproduce as long as it is given? Then medication would have to be given until the bacteria die naturally.

How do viruses differ from bacteria fungi and parasites?

Viruses aren't as "living" as the other three that you mentioned. The only thing viruses have in common with them is that they move. Viruses do not eat, breath, grow, or reproduce. They do reproduce, but not independently.

Instead of taking over the host right away, many viruses go into a dormant stage, which means that they wait for the right time and climate (which could even take over a year, like most symptoms of HIV, for example) to do their job. Also, viruses do not attack until inside the cell wall. From there, the virus sends genetic material into the cell membrane, and the cell immediately goes to work reproducing the virus.

The only reason viruses care to survive is to reproduce, and we don't know why.

The first paragraph should have mainly answered your question, I just wanted to make sure you know the important facts--they help. Please give feedback! Thanks.

What are bacteria that live in or on plant and animal tissue without harming it called?

Bacteria that live in or on plant and animal tissue without harming it are called commensal bacteria. These bacteria benefit from the environment provided by the host without causing harm or benefiting the host in return.

Which bacteria would you most likely find in the human intestinal tract?

The most common bacteria found in the human intestinal tract are Bacteroides, Firmicutes, and Actinobacteria. These bacteria play important roles in digestion, nutrient absorption, and overall gut health.

Why are bacteria and other microorganism used to fight pollution?

Bacteria have an amazing ability to adapt to almost any food source. Scientists expose bacteria to soils rich in various pollutants and eventually one or more decide they can use it as food and multiply. The scientists culture this bacterial strain until they have marketable quantities then sow them into contaminated soil at a spill or other polluted site. The bacteria eat at the contamination until it is all gone.

In sewage treatment plants bacteria have been eating waste water contaminants for years, Normal bacteria eat sewage but in industrial waste there are often organic poisons that would kill normal microbes. They adapt however and eventually are happily eating phenols and oils. Refineries often swap bacterial colonies to meet start-up colonization of their treatment systems.

How does staphylococcus epidermidis obtain its energy?

Staphylococcus epidermidis is a facultative anaerobe, meaning it can switch between using oxygen and fermentation for energy production. It primarily obtains its energy through fermentation of carbohydrates, such as glucose, to produce ATP for cell processes. This bacterium can also utilize other nutrients like amino acids and lipids for energy production when carbohydrates are not available.

How does lactobacillus acidophilus reproduce?

Lactobacillus acidophilus reproduces by a process called binary fission, where the bacterial cell divides into two identical daughter cells. This type of reproduction allows the bacteria to rapidly multiply and increase its population.
