- Notes
- TOGO M2176 imports ATCC Medium 1108 as Renibacterium KDM-2 medium. ATCC 1108 lists 1.0% w/v peptone, 0.05% w/v yeast extract, 0.1% w/v L-Cysteine . HCl, 1.5% w/v agar, and 20.0% fetal bovine serum. The ATCC preparation dissolves peptone, yeast extract, and cysteine in 80% final-volume distilled water, adjusts to pH 6.5 with NaOH, adds agar with heat, autoclaves for 15 minutes at 121 C, cools to 45 C, and adds serum at 45 C.
