if you have a dense laboratory culture of bacteria in a petridish, what is the best measure to report its density?
- Standard plate count/Colony forming units (CFUs): Manual Colony count upto 30, afterwards will be mentioned as Too numerous to count (TNTC)
- Serial dilution with standard suspension(made up of McFarland Turbidity Standards)
- Direct microscopic count
- Turbidimetric Measurement: Measurement of cell concentration in suspension by optical density
