For the 5 thousand bacteria case, 0 would have done the trick.
For example, you could put one cup of cold press coffee into a pot and add 9 cups of water.Basically, it s awfully hard to divide something into teeny-tiny pieces unless you first blow that something up and make it huge.The worried nurse hands you a vial of 10 mLs of Frank s blood.5000 bacteria: the diluted sample will contain ON average.5 CFUs - meaning that any given sample will probably contain either 0 or 1 CFU.Or even 42,100,000 cells.In the table below, click on the button corresponding to the plate that should be wwe raw game full version for pc softonic used to estimate the original pm65 to pdf converter concentration of bacteria: dilution factor,000 0,000 1:1,000,000,000,000 count answer Pretty straightforward, right.Hint: this applet previews the module on bacterial growth rates a bit.Below, you can practice a couple more times.Of course, lots of things can be diluted, not just blood samples So let s see what the process of diluting looks like.In the case of wimpy coffee, it was 1/50,.02.
In fact, even with our absolutely flawless technique, the best we can say is turns one way game that there are between 41,500,000 and 42,500,000 cells.
So, we re going to take a little bit of our culture, put it on a plate, and grow.
Voila, soup with only 90,000 peas per liter.
We want your opinion!
It doesn t really matter how much stock you start with, the important thing is to take out the right fraction of it a tenth, a hundredth and then add enough water to get back to the initial volume.
Luckily, the kingdom measured in metric only.You might not be able to do this in your sleep, but at least work at it until it makes sense Design some dilutions You have a stock with an estimated 40,000 CFUs per mL, and you need to dilute to an estimated 500 CFUs.Of course, we don t want to have to draw pictures every time we do a dilution, so we could simply write: 1 cup coffee 9 cups water - 1/10th as strong as the original.It s the over part of one over eleven.And, if you roll over the image, you will see the plate counts I expect if my original guess 42 million was approximately correct.Great, it didn t work the first time, so now we re going to do it again.The answer of course is 2100 2 approximately 4200.Ideally, therefore, we would like to get 100 bacteria on the plate that we count.Talk about far-reaching applications of mathematical concepts.So we might do 5 dilutions and grow up 5 plates.Take 1 mL of that and put it in 49 mLs of water.And all that matters is that we get the ratio right hmm let s say we started with a hundredth of a pot of the old soup and added 99 hundredths of a pot of water.And clearly, this module is going to pick that method apart and pound it into the figurative whiteboard.Take 1 mL of that and put it in 999 mLs of water.
