Calculating the Chi Squared Value from Bacterial Enumerations
A Poisson Distribution is used to describe count data that is distributed randomly. Examples of random counts are radioactive disintegrations per minute, numbers of moths found per tree, and ot
Enumerating Bacterial Culture by Spread Plate Method
Questions: 1) What do microorganisms need to grow?
2) What does counting colonies tell us about the bacterial populations? Why does counting colonies work?
3) What are the limitations of a direct count
Aseptic technique refers to a procedure that is performed under sterile conditions. This includes medical and laboratory techniques, such as with microbiological cultures. The purpose of aseptic technique is to prevent the culture that i
