Terrific Broth is rich nutritional medium developed by Tartoff and Hobbs supporting luxurious high density growth of E.coli and a higher yield of plasmid DNA compared to LB type media. Recombinant E. coli cells have an extended growth phase in Terrific medium.
Terrific Broth medium is used with glycerol as a carbon source. Unlike glucose, glycerol is not fermented to acetic acid.
Tryptone and Yeast are present in the medium in elevated concentrations and provide nitrogen, vitamins and cofactors for a luxurious growth.
Potassium phosphate is present in Terrific broth buffered to balance the pH and subsequently prevent cell death due to a drop in pH.
