Preparation of Medium: Add agar, peptone, NaCl, and yeast extract
to distilled/deionized water and bring volume to 1.0L. Mix thoroughly.
Adjust pH to 8.0. Autoclave for 20 min at 15 psi pressure–121°C. Cool
to 45°–50°C. Filter sterilize separately the lactose solution, Bromthymol
Blue solution, sodium thiosulfate solution, glucose solution, and maranil
solution. To the cooled, sterile agar solution aseptically add 27.0mL of
sterile lactose solution, 10.0mL of sterile Bromthymol Blue solution,
2.0mL of sterile sodium thiosulfate solution, 1.2mL of sterile glucose so-
lution, and 1.0mL of sterile maranil solution. Mix thoroughly. Adjust pH
