| Add 900 mL of deionized water to 24 g of yeast extract, 20 g of tryptone, and 4 mL of glycerol. Shake or stir until the solutes
have dissolved and sterilize by autoclaving for 20 min at 15 psi (1.05 kg/cm2). Allow the solution to cool to ∼60°C and add 100 mL of sterile phosphate buffer. Store TB at room temperature; it will keep
for at least 1 yr.
