Overview

External ontology

TOGO:M148 — Eubacterium Medium

Applications

Microbial cultivation

Notes

TOGO M148 imports JCM_M157 as Eubacterium Medium and lists 1 L distilled water, 10 g yeast extract, 1.3 g sodium thioglycolate, 0.3 g beef brain powder, and 29.5 g Fluid thioglycolate (BD-BBL). MediaDive J157 preserves the same JCM formula as 1000 ml water with the same four dry-component amounts. The JCM GRMD=157 URL named by TOGO and MediaDive no longer returns the recipe; no pH, incubation condition, or preparation steps are available from these accessible source records.

Ingredients (5)

#	Ingredient	Concentration	Ontology	Notes
1	Beef brain powder	0.3 G_PER_L		TOGO M148 and MediaDive J157 list 0.3 g/L Beef brain powder; this undefined biological powder is retained as an opaque complex component.
2	Sodium thioglycolate C2H3O2S.Na 114.101 g/mol	1.3 G_PER_L	CHEBI:86481 sodium thioglycolate	TOGO M148 / MediaDive J157 lists 1.3 g/L Sodium thioglycolate.
3	Yeast extract	10.0 G_PER_L	FOODON:03315426 yeast extract	TOGO M148 / MediaDive J157 lists 10.0 g/L Yeast extract.
4	Fluid thioglycolate (BD-BBL)	29.5 G_PER_L		TOGO M148 lists 29.5 g/L Fluid thioglycolate (BD-BBL), corresponding to MediaDive J157's BD-BBL fluid Thioglycolate row; this is a commercial medium product, not a single thioglycolate ion.
5	Distilled water H2O 18.015 g/mol	1.0 L	CHEBI:15377 water	TOGO M148 lists 1 L distilled water, matching MediaDive J157's 1000 ml water basis.
