<Features>

 

JM Medium is optimized for gut microbial culture which universially supports the growth of gut microbes.

 

By using JM medium, we were able to construct a gut microbe library consistin of more than 2,200 species.

 

Research has proven that JM media has dramatically stimulated gut microbe's growth.

 

An overnight culture on JM agar medium can take sufficient for colony counting.

 

Through JM medium, You can also discover newly gut microbes.

 

 

 

<Constitution and Function>

 

  • Base powder : Composed of factors that support intestinal microbial culture.

 

  • JM supplement : Mixture consisting of 19 plants to the basal medium dramatically stimulated the growth of gut microbes. 

(* JM Supplement is an "insoluble" component, so it is normal not to dissolve in water.)
