Summary Introduction
To answer:
Three indirect methods used for counting microorganisms.
Introduction:
The microbial growth refers to an increase in the number of cells, not the cell’s size. Binary fission is the mode by which the bacteria divide and grow. The counting methods of bacteria are categorized into two broad methods, namely direct method and indirect method.
