๐Ÿ“š Microbiology Concepts Explained
๐Ÿ“ˆ Growth Rate
r = (ln(Nโ‚œ/Nโ‚€)) / t
Where Nโ‚€ = initial cells, Nโ‚œ = final cells, t = time
โฑ๏ธ Doubling Time
Tโ‚ = ln(2) / r
Time for population to double at growth rate r
๐Ÿงด Dilution Factor
DF = Vโ‚ / Vโ‚‚
Ratio of initial volume to final volume
๐Ÿงซ CFU Calculation
CFU/mL = (colonies ร— dilution factor) / volume plated
