6.6-10 Culturing Microorganisms Microbiology

6.6 Microbial Growth Binary Fission Asexual reproduction One cell splits into two identical clones.

6.6 Microbial Growth Generation Time How long it takes the population to double during the exponential phase of growth.

6.6 Microbial Growth Growth Rate is usually determined by conditions such as temperature, pH, available resources and space.
