how fast does pseudomonas grow in vivo?

Generally the speed of this depends on the weakness of the immune system and age.  Could go very rapidly in very aged.\n\nAlso in immune compromised such as HIV/AIDS.\n\nSometimes very old people acquire a pneumonia and die in a very few days.\n\nAntibiotics work best in healthy people.  But not everyone is saved.

mould or any microorganisms require  various  enzymes to carry out difernt unction and these enzymes work best at a perticuklar temperatour if the temperatur goeslower or above the growh is hampered and thus wen the mould is kept in fridge their enzymes dont wrk to the maximum capacity their ability to wrk gets weeker and thus the grown is also slow...... i gess u  got the reuired explanaion

Bacteria is constantly mutating. Sooner or later it'll mutate into a strain that is resistant to antibiotics

Well, apparently, they grow quite well on certain caterpillars ...\n\n:-P\n\n... but, seriously, AFAIK the bacterium is not too fussy, or (as we microbiologists generally call it) "fastidious" about its growth requirements.  I assume it will grow on any "minimal" medium, that is, maybe a bit of Yeast Exatract, + / or tryptone or meat extract, with or without addition of agar.  You did not say whether you wanted a liquid or solid growth medium.\n\nWe find Bacillus species as reasonably - common contaminants from the environment.  Our media are designed to isolate bacteria important to human health, so they are more nutritious than Bacillus thuringiensis would need (AFAIK).\n\nIf you do grow it, be careful with it; many members of this genus produce toxins.  I suspect that Bt toxin might not be very good for humans, too.  IMO, it is probably unwise to try to grow bacteria, unless you have appropriate training and laboratory equipment.  For example, you need to sterilise media and equipment, and properly dispose of wastes, in a safe fashion, and according to local bylaws etc.\n\nI am a microbiologist.

Most of the bacteria that can be cultured represent only a tiny fraction of what's out there. Bacteria exist in practically every niche observable but in general, the best way to cultivate bacteria is to simulate their natural environment. That's why many infectious bacteria are grown on agar (a sugar similar to the ones found in our body) and incubated at 37 degrees celsius (the temperature of the human body)

The population can be modelled using the following equation.\nP(t) = P(initial) * 2^(t/10)\n\nYou know P(90) = 90000:\nSo plug this in:\nP(90) = 90000 = P(initial) * 2^(90/10)\n\n90000 = P(initial) * 2^9\n\nSolve for P(initial):\nP(initial) = 90000 / 512\nP(initial) = 175.78125\n\nHere are the details:\nP(0) = 175.78125\nP(10) = 351.5625\nP(20) = 703.125\nP(30) = 1,406.25\nP(40) = 2,812.5\nP(50) = 5,625\nP(60) = 11,250\nP(70) = 22,500\nP(80) = 45,000\nP(90) = 90,000\n\nYou can also do this working backwards, just dividing by 2.  So at time t = 80, you have half the population (45,000) at t = 70 you have half of that (22,500), etc.  Until you get to t = 0.\n\nSo the answer is:\nInitial population = 175.78125 ≈ 176 bacteria

Bacteria does not grow at freezing temperatures, but the temperature does not kill it. Heat  will kill bacteria if it is hot enough, but there is a range where bacteria like to grow. In food microbiology, we are told not to keep food between 40 and 140 F because that is where bacteria will grow.\nAs far as ice gathering bacteria, if it is open to the air, the temperature makes no difference.

It depends on the bacterium. For E. coli (common lab bacteria) 20-30 minutes is an average doubling time, but different strains vary.\n\nI heard something somewhere about a weird form of bacteria that lives miles underground in granite formations and only divides once every ten thousand years, or something crazy like that. I can't give you a source, it's just a freaky thing off the top of my head that I haven't gone to the trouble to confirm. My contention is that if reincarnation is true, that would be the *worst* thing to come back as. So mind your karma.\n\nPart of the reason it would be the worst is that bacteria reproduce by one cell dividing into two, so as long as there are any of that strain still alive, it hasn't really died.\n\nThey can die though. In a liquid culture you can tell because of a lot of turbidity (cloudiness) some of which is from cells and some from debris from dead cells. Or, you could have agar plates that get really nasty and dried up, and most of those bacteria are probably dead. Or you could tell because they look really crappy under a microscope. If you try to streak it and grow it on a plate and it doesn't grow, it's probably dead.

Hi there, \n\nMany types of bacteria undergo cell division by a procedure called 'Binary Fission'\nYeast does not undergo cell division, however, it reproduces through 'Budding'\n\nHope this helps. If not, I'd be glad to assist you further. Bye!!\n\nrule wid style n luv@vinny

Here is a short answer for you.  :)\n\nGram negative bacteria have a lipopolysaccharide (LPS) molecule attached to their outer cell membrane.  LPS is an endotoxin that triggers an immune response in the form of fever and eventually shock as the toxin accumulates in the bloodstream.  \n\nGram positive bacteria do not have LPS.\n\nP.S.  There is no such species as Pseudomonas aureus  :)

Depends on the media in which it propagates. The temperature and the pressure also slightly affect the speed. In air it's about 330 m/s.

Well, if you want to measure their growth in milk you need:\n\nPure culture of the bacteria in question, sterile milk, sterile glass tubes and a spectrophotometer.  This will measure the density of the bacteria in liquid culture.  I don't know what equipment you have access too (pipetts, tubes, a spectrophotometer etc).\n\nIf you've isolated the bacteria from milk and want to just measure their growth in "whatever", you can use any sterile growth medium that supports the growth of the isolated bacteria.  Again, measuring growth is most easily accomplished by use of a spectrophotometer.  \n\nGrowing bacteria on a plate to decide which grows faster is fairly insane, unless they have significant differences in growth.  I mean, are you going to stare at an agar plate for 24 hours just to see that at 14 hours 5 minutes a tiny pinpoint on plate A was visible, but it took 15 hours and 22 minutes for a colony of the same size on plate B?  No, of course you're not, it's not even plausible.\n\nWith liquid culture, you can take readings every hour for 8 hours and at 24 hours or something.\n\nYou can also dilute and spread-plate the bacteria from liquid cultures onto agar plates if you have your heart set on using them and achieving an exact count for bacterial populations.  But use of a spec still allows for comparisons between species, even without an exact population number.

well, there are many factors that led to the growth of bacteria..first, the temperature. Temperature affects the growth of bacteria. Like for instance, there are several bacteria that thrive in room temperature, and there are those that thrive in very cold or very hot temperatures. Second, the pH affects the growth of bacteria also. For example, there are micro organisms that thrive in very acidic env't (ex. Candida albicans which causes Candidiasis), also there are those that thrive in alkaline env't.Third, there are special micro organisms that thrive in extreme environment. For instance, there are those that thrive in very saline env't, called extreme halophiles. There are also that thrive in methane- rich env't.\nThere are other factors that lead to the growth of micro organisms but one thing is for sure...micro organisms are everywhere even in the place where no other living things can thrive...

the Pseudomonas protein may be interacting with another Pseudomonas-specific protein and forming the larger molecular weight complex.  does the loading buffer have a reducing agent like DTT to reduce disulfide bonds?
