Source: https://togomedium.org/medium/M159 Original source: JCM - JCM_M168 Original URL: https://www.jcm.riken.jp/cgi-bin/jcm/jcm_grmd?GRMD=168 Source preparation excerpts: "Add components to distilled water and bring volume to 1.0 L."; "Unless otherwise stated, sterilize media by autoclaving at 121°C for 15 min.". These instructions are not converted into an inferred step ordering. Separate JCM168 excerpts: "Adjust pH to 7.0-7.2."; "For preparation of solid medium, add 20.0 g/L agar.". The agar option is selected only for M160; liquid formulations remain unchanged.
