Suspend 43.41 gms. of B276 in 1000 ml. distilled water. Boil with frequent agitation to dissolve the medium completely. Add 0.02-0.2% agar in broth if desired. Sterilize by autoclaving at 15 lbs pressure (121°C) for 15 minutes. Cool and add 5% sterile defibrinated blood if desired. Mix well before dispensing. Avoid overheating and photooxidation of the medium, as it will retard the growth of bacteria.
