Introduction to Microbiology (CP4089) - Experiment 4: Colony Count Methods: Viable Cell Number of Commercial Active Dried Yeasts

Summary This purpose of this experiment was for students to do the colony count methods, estimating the viable cell number of commercial active dried yeasts (ADY). This experiment allowed the students to perform the plate count technique by serial dilution and two common methods, spread plate and pour plate to determine the colony forming unit (CFU) of yeasts A ten-fold dilution is used in this experiment, the sample is diluted until it reached the 10-9 …
