General description

GranuCult® Nutrient agar is a universal culture media for cultivating less fastidious microorganisms. The peptone and beef extract provide sufficient nutrients for the growth of non-fastidious bacteria. Both are the sources of nitrogen, vitamins, carbon, and amino acids, while agar is the solidifying agent.

Application

GranuCult® Nutrient Agar is used for the cultivation of non-fastidious bacteria.
