Original name: JXT Medium

Overview

External ontology
TOGO:M217 — JXT Medium
Applications
  • Microbial cultivation
pH range
{'min': 7.0, 'max': 7.2}
Notes
TOGO M217 imports JCM Medium 224 as JXT Medium. JCM 224 lists 1 g Yeast extract from BD-Difco, 1 g Trypticase peptone from BD-BBL, 1 g Na2S2O3·5H2O, and 1 L seawater at pH 7.0-7.2. The source says to use filtrated natural seawater or artificial seawater such as Jamarin S from Jamarin Laboratory, and to autoclave media at 121 C for 15 min unless otherwise stated.
