Recipes
We experimented with several types of growth media for Shewanella growth, both aerobically and anaerobically. The most effective growth media recipes are listed as follows.
Orianna's growth media
- 50 mM K-PIPES 18.925 g/L
- 7.5 mM NaOH 7.5 mL/L
- 28 mM NH4Cl 1.5 g/L
- 1.3 mM KCl 433 uL/L
- 4.3 mM NaH2PO4 0.59 g/L
- 100 mM NaCl 5.84 g/L
- 18 mM Lactate 1.62 g/L
- 10 mL Vitamin solution
- 10 mL Amino acid solution
- 10 mL Trace mineral solution
LML medium (for anaerobic Shewanella growth)
- 0.02% yeast extract
- 0.01% peptone
- 20 mM lactate
- 10 mM HEPES [pH 7.4]
LML agar (for Shewanella reduction test)
- LML medium
- 0.8% agar
- 2 mM MnO2- Mn(IV) oxide (turns from brown to clear upon reduction to Mn(II))
(LML recipes from [http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pubmed&pubmedid=9829939| Beliaev and Saffarini 1998])
Chamber media
- 5.844 g/L 100mM NaCl
- 15.1185 g/L 50mM PIPES (hydrogen)
7.0 pH
Phosphate buffer
- 2.918 g/L Monosodium phosphate, monohydrate
- 4.095 g/L Disodium phosphate, anhydrous
- 5.844 g/L 100mM NaCl
7.0 pH
Lactate solution
- 13.51 g/L Lactic acid
- neutralize to pH 7 with NaOH
