Selectively isolate and cultivate Mycobacterium spp. using Lowenstein-Jensen (L-J) Medium, L-J Gruft, and L-J Mycobactocel.
• Selective– Antibiotics in the medium make the medium selective forMycobacteriumwhile inhibiting contaminating bacteria.
• Ready to use– Convenience of prepared media.L-J Medium is a glycerated egg-potato medium. The glycerol and egg mixture provide fatty acids and protein required for the metabolism of mycobacteria. L-J Medium was modified by Gruft by adding ribonucleic acid as a growth stimulant and penicillin and nalidixic acid as selective inhibitors of contaminating bacteria^5. Ribonucleic acid increases the percentage of positive cultures over the standard L-J Medium. The selectivity of L-J Medium was increased by incorporating cycloheximide, lincomycin, and nalidixic acid and was formulated by Petran and Vera^6.
