Current Protocol for 100mL of Media
Adopted From Supplemental Information In [http://www.sciencemag.org/content/329/5991/559.full Microbial Biosynthesis of Alkanes Science Report]
Long Term Stocks to Prepare
Store at room temperature unless otherwise noted
- 1L of 1M Bis‐Tris (pH 7.25)
- 10mL of 1mg/mL Thiamine (store at -20 in 1mL aliquots)
- 10mL of 10% Triton X-100
- 1M MgSO4
- 0.1M FeCl3-6H2O
100mL M9 minGlucose Media Prep
ADD IN ORDER, make sure you have a sterilized Erlenmeyer flask for the initial mixing and a sterilized bottle to sterile filter into
Constantly mix using a stir bar
- 75mL ddiH2O
- 3g glucose (Final 3%, 100% = 1g/mL)
- 0.6g Na2HPO4
- 0.3g KH2PO4
- 0.05g NaCl
- 0.2g NH4Cl
- 20mL of 1M Bis-Tris (pH 7.25)
- 1mL of 10% Triton
- 100uL of 1mg/mL thiamine
- 100uL of FeCl3-6H2O
- 100uL of MgSO4
Once media is prepared sterile filter into a pre-sterilized glass bottle
General Production Protocol
- Grow 5mL of cells in Terrific Broth with Antibiotics overnight to saturation in 14mL culture tube
- Measure OD (should be roughly 1.5)
- Spin down cells at 4000rpm for 10 minutes
- Resuspend in 1mL of sterile ddiH2O and transfer to a 1.5mL Eppendorf tube
- Spin down cells at 4000rpm for 10 minutes
- Resuspend in 1mL of sterile ddiH2O and transfer to a 1.5mL Eppendorf tube
- Spin down cells at 4000rpm for 10 minutes
- Resuspend in 0.7mL of Production Media with Antibiotic
- Transfer to a 24mL 13x250
- Seal the top with alluminum foil and grow at 37degC for 48 hours
- Extract by adding 0.7mL of EthylAcetate, vortex, transfer to an Eppendorf tube, and spin at max speed for 1minute.
- Remove 200uL of the top Ethyl Acetate layer into a glass vial with insert
- Run sample on GC-MS and identify Alkanes
