Nutrient Broth is used for the cultivation of many species of nonfastidious microorganisms.
Nutrient Broth has the formula originally designed for use in the Standard Methods for Examination of Water and Wastewater. It is not a recommended bacteriological medium in later editions of this publication. It is one of several nonselective media useful in routine cultivation of microorganisms.
This relatively simple formulation supports the growth of nonfastidious microorganisms due to its content of peptone and beef extract.
