Do anaerobic bacteria generally have longer lifespans than aerobic bacteria?

Since bacteria 'live' until they divide into two daughter cells, you can restate the question as "Do anaerobic bacteria have longer times between division?" The answer to this is yes. Anaerobic growth is less energetic because most alternative electron acceptors (since oxygen isn't an option) have less reduction potential. So, less cellular energy is available to undergo

Is rhizobium aerobic or anaerobic bacteria?

Rhizobium is aerobic, which has a lot to do with the fact that Nitrogen fixation is an energy intensive process which requires large amounts of energy that could not be produced reasonably through anaerobic pathways.However, Nitrogenase is irreversibly damaged by exposure to Oxygen, so oxygen exclusion is a necessary pre-requisite for Nitrogen fixation. These two facts lead

Is the bacteria on washed clothes aerobic or anaerobic?

Yes, they are aerobic. Most public water supplies are fairly well aerated, with quite a lot of oxygen from a bacterium's perspective. Regardless, the water in a washing machine is oxygen-saturated by all the splashing around.Unless you have a front-loading washer, though, the washer is not airtight, and

What are some examples of aerobic bacteria and anaerobic bacteria?

Mention bacteria and nearly all of us assume them to be disease-causing microbes. However, not many of us know that bacteria play a major role in the overall functioning of our ecosystem. Believe it or not, a major biomass of the earth is contributed by minute

What are some examples of aerobic bacteria?

Bacteria can be divided into following types on the basis of use of oxygen:Aerobic: which require oxygen for their growth they can be:      a. Obligate Aerobic: survive only if oxygen is present example;                          Mycobacterium tuberculosis       b. Microaerophile: That require lower amount of oxygen i.e. 2 to

What are the differences between facultative and obligate anaerobe?

Facultative : occurring optionally in response to circumstances rather than by natureObligate: require; restricted to a particular function or mode of lifeA facultative anaerobe does not require oxygen for respiration i.e. can make ATP by aerobic respiration in the presence of oxygen, but can

What are the examples of aerobic and anaerobic bacteria?

Aerobic bacteria are those which utilize oxygen to oxidise the substrate during cellular respiration. Some examples of aerobic bacteria include: Bacillus, Pseudomonas aeruginosa, Mycobacterium tuberculosis, Nocardia etc.Anaerobic bacteria are bacteria that do not live or grow when oxygen is present. Some examples include Actinomyces, Bacteroides, Clostridium, Fusobacterium, Peptostreptococcus, Porphyromonas, Prevotella, Propionibacterium, Veillonella etc.

What is a facultative anaerobe?

A facultative anaerobe is, simply speaking, an organism which possesses the ability to survive in an environment containing oxygen while growing even more efficiently in an environment without oxygen. Facultative anaerobes can optionally function without oxygen by two main mechanisms; fermentation and alternate terminal electron acceptors. In fermentation, glycolysis is performed and pyruvate is

What Is facultative anaerobic bacteria?

Okay, imagine that you ended up in an environment where there was no oxygen.You'd die, right?Except...you can also breathe carbon dioxide (well, technically, you already do that, and you have to if you want to live), but the carbon dioxide does not function as efficiently in releasing energy for your cells as the

What is rhizobium bacteria?

Rhizobium is a bacterium ( sing. Of bacteria) which can convert atmospheric nitrogen into usable form for plants . It cannot make its own food . So, it often lives in the root of some lugumes and provides them with nitrogen. In return, the plants provide food and

Ammonification by ammonifying bacteria takes place in which condition, aerobic or anaerobic?

It is an anaerobic process. Ammo is step of Nitrogen cycle.Step 1- Nitrogen Fixation : special bacteria called Diazotrophs, eg. Azotobacter, Rhizobium which have Nitrogenase Enzyme that convert Nitrogen to Ammonia to be used by plants.Step 2- Ammonification : Organic Nitrogen is converted to Ammonium ion. Enzymes involved are GS, GOGAT, GDH etc.Step 3- Nitrification : Ammonium ions

Are there any predatory type organisms that attack virus or bacteria?

Eat bacteria? Yes, although whether it's predatory is debatable. Plenty of bacteria and protozoa feed on bacteria. The amoeba is a common example you can observe under a microscope.

Can anaerobic bacteria survive in space?

They can absolutely survive!Earth Bacteria Survive a 553-Day Space Exposure on the Exterior of the ISSAs for reproducing, I could not find any articles addressing it specifically, but I don't see why not.Edit (2013-11-08): There used

Do bacteria have bacteria?

Yes.We know that bacteria range in size from 0.2 ┬Ám to nearly a mm. That's more than a thousand-fold difference, easily enough to accommodate a small bacterium inside a larger one.Nothing forbids bacteria from invading other bacteria, and in biology, that which

Do bacteria have emotions?

Emotions as commonly understood and defined require a nervous system, which bacteria plainly don't have. That definition of emotions makes this an uninteresting question that really is not worth answering.But if we look beyond the machinery of emotions to their purpose (although inferring purpose is always dangerous in biology), we can fashion

Do bacteria have feelings?

Bacteria respond to chemical stimuli using a chemosensory system that works like a bacterial brain that communicates to the cell whether it should move towards a chemical attractant such as amino acids or away from toxic substances. A network of integral membrane chemoreceptor and signaling proteins work together by responding to chemical cues and

Do bacteria respire?

Not in the conventional sense that you might be familiar with.They get their energy (in the form of ATP) by cellular respiration. This may be either anaerobic or aerobic. Anaerobic basically means that they do not utilize oxygen. Whereas, in aerobic respiration, oxygen is utilized.Examples

Do you think we'll ever be in contact with another "advanced" species like ours? We're just apes that drive cars but honestly is there some like us out there or most likely bacteria or other lesser life

No, not unless we can radically improve our speed of travel in space or somehow develop faster than light communication.The nature of our Electro-Magnetic communications is that they are limited to light speed and mostly become undetectable outside of 100 light

Does a bacteria decompose the nitrogeneous present in the sewage? Does it multiply during this process?

Nitrogen can be fixed from air in specific bacterial species in certain vegetable plant roots as nitrate; N2 is an element, so can not be decomposed further.You probably wanted to know if nitrogenous materials in sewage (mud) can be decomposed by

Does E.coli rely on other organisms to live?

The vast majority of Escherichia coli are harmless commensals. A few strains have shown pathogenic or toxigenic characteristics, and these are known as Verotoxigenic (VTEC) strains. The most well-known is the enterohemorrhagic E. coli O157H7, which among other things, is resistant to pH down to 2.7, meaning that it

Does wine turn sour because of bacteria? If yes, is it aerobic or anaerobic bacteria which causes so?

Bacteria is a huge contributor in the souring of wine; ethanol rarely oxidizes easily by air; rather, the bacteria naturally present in the grapes can change the sugars in the grape juice or the alcohol in wine into acetic acid, giving it a vinegary taste. However, these bacteria need oxygen to grow, (meaning they're

Is bacteria an obligate parasite?

Is bacteria an obligate parasite?Obligate parasites are dependent on their host for their nutrition and completion of their life cycle. Most bacteria are free living but pathogenic bacteria are often obligate parasites and grow only within a living host cell.Of Terms in Biology: Obligate ParasiteExamples of obligate parasite bacteria include Rickettsia species,

Bacteria are microscopic unicellular organisms. They possess an outer capsule or alternatively a slime layer for adhesion and that confers virulence. They have a cell wall and a cell membrane around the cytoplasm. The cell wall is made of peptidoglycan.The cytoplasm has many

What are examples of obligate anaerobes?

Obligate anaerobes are microorganisms killed by normal atmospheric concentrations of oxygen (20.95% O2). Oxygen tolerance varies between species, some capable of surviving in up to 8% oxygen, others losing viability unless the oxygen concentration is less than 0.5%. An important distinction needs to be made here between the obligate anaerobes and the microaerophiles. Microaerophiles,

Rhizobium is a bacterium ( sing. Of bacteria) which can convert atmospheric nitrogen into usable form for plants . It cannot make its own food . So, it often lives in the root of some lugumes and provides them with nitrogen. In return, the plants provide food and shelter to the bacterium.

What is the application of anaerobic bacteria?

Anaerobic bacteria are used for wastewater treatment because they digest organic matter which otherwise be destined to be dumped at sea or dumped in landfills.Methane and power produced in anaerobic digestion can be used to replace energy derived from fossil fuels, and hence reduce emissions of greenhouse gases- the

What is the difference between anaerobic respiration and fermentation?

In anaerobic respiration, as in aerobic respiration, electrons are accepted by the substance being oxidized, but the reduced compounds that accepted the electrons are ultimately not themselves oxidized by oxygen, but some other source of oxidizing potential.In fermentation, the substance being fermented disproportionates, undergoing an

What is the difference between rhizobium bacteria and bean plants?

What is the difference between rhizobium bacteria and bean plants?Short answer: Same as the difference between cyanobacteria and bananas - I.e., bacteria (like rhizobia and cyanobacteria) are prokaryotes, while bean plants (and bananas) are eukaryotes.That answer is not very helpful ... so instead I answer this: What is the relationship between rhizobium (bacteria) and

Bacteria and Fungi are very different and filogenetically distant groups. Differencies are numeorus but similarities are the following:Both fungi and bacteria have cell walls (although quite different in structure and composition)Most bacteria and all fungi obtain energy from aerobic respiration (respiration in Bacteria is a bit different than in Eukaryotes

What is the symbiotic relationship between rhizobium bacteria and legumes?

Rhizobia sp. bacteria can be found in the root nodules of legumes. These are swellings (clusters of cells) that can be found along the roots. The Rhizobia carry out the process known as nitrogen fixation. Plants need nitrogen to produce protein but they can't

What would happen if all bacteria and viruses disappeared suddenly?

We would be in troubleWhatever the reason that causes the bacteria and viruses cease to exist would effect all the other living-organisms as well.you cannot have any more fermented products like dairy,bakery,alcohol etc.There would be no decomposition/degradation/bio-remediation, would have added to the growing garbage/waste problem taking up our limited living space,recycling of waste/minerals back to the earth will

What would most improve your prognosis for surving an E. coli infection?

Surviving an E-coli infection may requirea Doctor visit.Escherichia coli (E. coli) bacteria normally live in the intestines of healthy people and animals. Most varieties of E. coli are harmless or cause relatively brief diarrhea. But a few particularly nasty strains, such as E. coli O157:H7, can cause severe abdominal cramps, bloody diarrhea and vomiting (source 1).Symptoms (source

Few bacteria are useful to us they are:LactobacillusThere are more than 80 species of the Lactobacillus genus of probiotics. One of these species, acidophilus, is the most frequently used good bacterium, according to the University of Maryland Medical Center. Lactobacillus acidophilus, also called L. acidophilus, resides in the intestines

Why is E.coli a model for bacterial genetics?

While not the simplest organism in terms of genetic simplicity (that honor goes to Carsonella ruddii with only 182 genes encoded by its 159,662 base pair genome), E. coli is a model organism because it's easily able to grow in the lab due

How do antibiotic resistant bacteria resist antibiotics?

Antibiotic resistance is caused by several mechanisms that could be either intrinsic i.e. changes in antibiotic target or acquired i.e by acquiring genes for resistance from other bacteria. Second mechanism is more dangerous as it makes bacteria resistant to antibiotics that could be shared among other bacteria. New

If warm water kills germs why can't cold water kill them off as well?

The reason warm water kills bacteria is because they are living your skin, which means the environment is around 95 degrees Fahrenheit, or 36 degrees Celsius. The sudden increase of heat really just means that molecules start moving faster. The bacteria can't handle this. However,

Does any online virus mimic its spread like a real world virus or bacteria?

It depends on how far you want to stretch your definition of
