Simple Media | General Purpose Media and Supportive Media examples
Nutrient agar,
Nutrient broth, and
TSB
•Promote growth of a certain growth of bacteria from a mixture of organism
•Contain specific nutrients WITHOUT additional supplements; following growth, colonies are sub-cultured to isolate desired organism
Enrichment Media
Enrichment Media examples
Alkaline Peptone water,
Selenite
CONTAIN ADDITIONAL SUPPLEMENT to support growth of fastidious organisms (Blood, vitamins and etc)
Enriched Media
Enriched Media examples
BOTH are used to isolate fastidious organism
