Application

The selective Lowenstein Jensen Medium is used for isolation of Mycobacteria sp. from contaminated specimens. Egg supplement enhances Mycobacteria growth. Malachite green, penicillin* and nalidixic acid* inhibit Gram-negative and Gram-positive bacteria. (* included in the Gruft Supplement)

Preparation Note

Suspend 37,2 g in 600 ml of purified water containing 12 ml of glycerol (Cat. No. 49769). Heat with frequent agitation and boil for one minute. Sterilize at 121°C for 15 minutes. Cool to 45-50°C and, aseptically, add 1 L of homogenised sterile eggs and if required 4 vials of Gruft Mycobacterial Supplement (Cat. No. 51803). Dispense into sterile culture tubes and coagulate at 85°C for 45 minutes in slant position.

Other Notes

We offer two media types: the superior granulated GranuCult® and the cost-efficient powdered NutriSelect® culture media, depending on your needs.
The designations basic, plus, or prime are added to indicate the quality control level, from basic quality control to standard QC plus to prime for full regulatory compliance.
