Step by step
Solved in 2 steps
- What is the difference between a mixed culture and a contaminated culture if they both contain more than one type of organism ?What is the purpose of the pour plate technique? If a pure culture is used to inoculate the plate, why are some colonies bigger than others?Why go to the trouble of creating a master plate (why not simply plate the initial culture on both nutrient agar and glucose-salts agar)?
