archaeoglobus_mcr_medium (CultureMech:002362)

Overview

External ontology

mediadive.medium:J1195 (source link unavailable) — ARCHAEOGLOBUS MCR MEDIUM

Applications

Microbial cultivation

Notes

JCM Medium J1195 is a supplemented parent-medium cross-reference: one liter of JCM Medium J1194 Methanothermococcus HHB Medium supplemented with 2.8 g/L Na2SO4. CultureMech recovered the J1195 row from the source-equivalent TOGO M1280 snapshot and keeps the J1194 base as a CultureMech parent-media link instead of flattening it into this record.
