Intended Use

Luria Bertani HiVeg Agar, Miller is used for cultivation and maintenance of recombinant strains of Escherichia coli for genetic and molecular studies and may be used for routine cultivation of not particularly fastidious microorganisms.

Composition

Ingredients Gms/Litre
HiVeg hydrolysate 10.000
Yeast extract 5.000
Sodium chloride 10.000
Agar 15.000
Final pH (at 25°C) 7.5±0.2

Formula adjusted, standardized to suit performance parameters

Directions

Suspend 40 grams in 1000 ml distilled water. Heat to boiling to dissolve the medium completely. Sterilize by autoclaving at 15 lbs pressure (121°C) for 15 minutes.

Principle And Interpretation

Luria Bertani HiVeg Agar, Miller is prepared by replacing casein enzymic hydrolysate with HiVeg hydrolysate which is free of BSE/TSE risks. It is the modification of Luria Bertani Agar formulated by Lennox (1) for cultivation and maintenance of recombinant strains of Escherichia coli. Luria Bertani HiVeg Agar, like the conventional media (2) are slightly different with double amount of sodium chloride. The medium is nutritionally rich for the growth of pure cultures of recombinant strains. Strains which are generally derived from Escherichia coli K12 are deficient in Vitamin B synthesis which are further modified by specific mutation to create auxotrophic strains and are unable to grow on nutritionally deficient media. HiVeg hydrolysate provides nitrogen and carbon while Vitamin B complex is provided by yeast extract. Sodium chloride provides sodium ions for the membrane transport and maintains osmotic equilibrium of the medium.
