What is a 1 10 serial dilution?
To complete a tenfold dilution, the ratio must be 1:10.
The 1 represents the amount of sample added.
The 10 represents the total size of the final sample.
For example, a sample size of 1 ml is added to 9 ml of diluent to equal a total of 10 ml.
1:10000 usually means 1 part to 10000 parts.
So in your case 1 part gel red to 10000 parts molten agarose.
Some people also use it to mean a dilution of 1 in 10000 (so 1 part gel red to 9999 parts agarose).

How do you calculate serial dilutions in microbiology?

Dilution factor = amount of specimen transferred divided by the total volume after transfer[amount of specimen transferred + amount of diluent already in tube].
Determine the dilution factor for each tube in the dilution series.
Multiply the individual dilution factor for the tube and all previous tubes._{30 sept. 2005}

What is the formula for CFU in serial dilution?

CFU/ml is equal to the total number of colonies multiplied by the dilution factor and this is divided by the volume of the culture plate.
CFU/ml – (Number of colonies*dilution factor) / volume of culture plate.
Bacteria/ml = 130*(10^6) which would be equal to 1.3*10^8 which can also be written as 130,000,000.
