A Theoretical Base of the Upper Limit of Plate Counting Method
Bulletin of Japanese Society of Microbial Ecology
The upper limit of viable cell count by plate counting method was studied theoretically and experimentally. The probability which k-cfus make n-colonies, A(k, n), was expressed by the following equation: where p is the ratio of colonies' average area to plate area. From this equation it was indicated that as the values of p increased, fused colonies increased and the counts of colonies decreased. Similarly this phenomenon was also observed at the experiment and calculated values coincided withdoi:10.1264/microbes1986.3.1 fatcat:m2da7t6v7bbqvave3naww3zni4
