What is the differences between a streak plate technique and a serial dilution technique?
what is serial dilution and spread plate technique
Is gram-positive cell wall sensitive to lysozyme?
While lysozyme will break down the cell membrane of some gram positive bacteira, it does not affect all gram positives therefore it is not a suitable means of separating the two. Serial dilution would be a much more effective method.
What is the major disadvantage of microbial counts performed by methods other than the serial dilution-agar plate procedure?
The total count includes dead cells as well as living cells.
Why is saline used in bacterial serial dilution?
Because the osmotic pressure of "plain" water can be too much for bacteria, causing them to pop, and throw off your colony counts during your serial dilutions. A buffered saline solution keeps the bacteria at their usual osmotic pressure. Typical saline is 0.85%.
Common mistake in dilution streak?

What are the method of estimating microbial population in soil?
Serial Dilution Plate Technique is the method to estimate soil microbial population by Dhinga & Sinclair in 1993.

What test is used to further identify unknown gram negative?
Serial dilution technique
What is the purpose of serial?
A common design for estimating the concentrations of compounds in biological samples is the serial dilution assay, in which measurements are taken at several different dilutions of a sample, giving several opportunities for an accurate measurement. Curren tly, serial dilution is a standard tool in the fields of toxicology and immunology.Serial dilution helps to choose a dilution which is relevant to our experiment.Often the standard which is given to you in the lab is far to strong for the experiment and it needs to be diluted. But equally the equipment has a detection limit so we can't dilute it to much, or if it is too diluted the experiment might not work.
What are the advantages and disadvantages of the serial dilution agar plate procedure?
Both force you to read your lab manual.
What is a ten fold serial dilution?
Serial dilution is usually 1/10 dilution. Therefore after a series of dilutions, you have a logarithmic curve of concentration (log10). Basically, if diluting 1/10 and starting off with 1 molar solution, first dilution = 0.1M, 2nd = 0.01M, 3rd = 0.001M. If making a 0.001M solution involved weighing out 0.005g of a salt for example, the error in making this solution out would be very large in comparison to weighing out 5g (1M) and diluting it 3 times by serial dilution. The benefit of it is mainly accuracy.
Who invented the traditional method in math?
Eisner Hewer invented traditional method in math
A colormertric method calls for the use of 0.1ml serum 5ml of reagent and 4.9ml of water what is the final dilution?
1:5
What are some advantages and disadvantages of the serial dilution agar plate technique?
the total count includes dead as well as living cells
How can you prepare solution 0.2 ppm from 1000 ppm?
dilute it 1 in 5000. likely best done with a serial or step dilution

Henry Ford invented the assembly-line method of production
