Colonies, dilution and volume plated to CFU.
Note
Count = 56 × 10⁶ / 0.1 mL = 5.60 × 10^8 CFU per g or mL.
Reference: Standard plate count calculation. Always follow your approved SOP and current pharmacopoeia.
CFU = colonies × 10ⁿ / volume plated
56 colonies at 10⁻⁶, 0.1 mL → 5.6 × 10⁸ CFU/mL
Count plates in the countable range (often 30–300).
