Composition of Medium
- 100 mg Naphthenic acids /L
(Modified Bushnell-Has medium)
- 1000 mg KH2PO4 /L
- 1000 mg Na2HPO4 /L
- 500 mg NH4NO3 /L
- 500 mg (NH4)2SO4 /L
- 200 mg MgSO4 ∙ 7H2O /L
- 20 mg CaCl2 ∙ 2H2O /L
- 2 mg FeCl3 /L
- 2 mg MnSO4 ∙ 2H2O /L
pH of Bushnell-Has Medium: 7.0
Protocol
Prepare naphthenic acids stock
- Mix 1 g naphthenic acid /L in dilute NaOH.
- Adjust pH of the solution to 10-11 to dissolve naphthenic acids into the solution as sodium salts
Making the Growing Broth
- Mix 20 ml naphthenic acid stock with 170 ml sterilized water in 500 ml erlenmeyer flask.
- Prepare 10 ml Bushnell-Has medium in vial
- Mix arbitrary amount of pseudomonas strain in B-H medium
- Transfer medium to erlenmeyer flask
- Incubation (aerobic conditions)
- Incubate stock at room temperature (20 °C) on a shaker at 200 rpm.
