Base

Dispense 2.5 ml portions of base solution into 13 x 100 mm test tubes containing inverted 6 x 50 mm fermentation tubes. Autoclave 10 min at 121°C. Final pH, 7.0 ± 0.2.

Sterilize stock solutions of carbohydrates (50% w/v) separately by autoclaving or, preferably, by filtration (0.2 µm pore size). Add 0.278 ± 0.002 ml stock carbohydrate solution to 2.5 ml basal medium to give 5% w/v final carbohydrate concentration.

For use with halophilic Vibrio spp., add NaCl to a final concentration of 2-3%.
