pH 6.5 ± 0.2 at 25°C
Substrate Solution:
Composition per 50.0mL:
Substrate........................................................................................0.1g
Preparation of Substrate Solution: Add substrate to distilled/de-
ionized water and bring volume to 50.0mL. Use gelatin, aliphatic acids,
or any alkalogenic carbon source. Mix thoroughly. Filter sterilize.
Preparation of Medium: Add components, except substrate solu-
tion, to distilled/deionized water and bring volume to 950.0mL. Mix
thoroughly. Gently heat and bring to boiling. Adjust pH to 6.5. Distrib-
ute into screw-capped tubes in 3.0mL volumes. Autoclave for 15 min
at 15 psi pressure–121°C. Cool to 45°–50°C. Aseptically add 0.15mL
of sterile substrate solution to each tube. Mix thoroughly. Allow tubes
to cool in a slanted position.
Use: For the cultivation and differentiation of microorganisms based
on their ability to utilize a variety of carbon sources such as gelatin, ali-
phatic acids, and other alkalophilic substrates.
