The standard plate count is performed so that the number of microorganisms found in a single gram of food can be determined. To be considered standard, there needs to be a minimum of 25 colonies on the plate.
this method is suitable for non aggregated cultures but the nature of the reaction must not be mycelial .
Chemical and physical requirements are determined by media and incubation
Requires incubation time
Cells may form aggregates
determines the number of viable cells
30-300
No. The standard plate count method is an indirect measurement of cell density of only viable bacterial cells. Optical density counting measure entire bacterial sample, the living as well as the dead bacterial cells.
it is used to count the colonies
I think disinfection, probably with chlorine
Because a colony on plate could be formed by more than one cell.
30-300
It is referring to heterotrophic plate numbers in water samples.
no
hehehe
go ask your mom
No. The standard plate count method is an indirect measurement of cell density of only viable bacterial cells. Optical density counting measure entire bacterial sample, the living as well as the dead bacterial cells.
the total count includes dead as well as living cells
write it properly here
Usually hundreds of colonies (>300) is considered as a high plate count.
what are the advantages of a metal plate
it is used to count the colonies
