Preparation

  1. Make up to <span class='amount' data-volume='1000'>1000</span> ml with natural sea water (Helgolandwasser).
  2. Autoclave at 121 °C for 20 min.
  3. After cooling, add the following filter sterilized components:
  4. Fill 300ml garden soil in a 1 l laboratory flask and fill up with H2Odist to 700 ml (The soil should not contain too much humus and not too much clay – avoid soil contaminated with fertilizers, herbicides or fungicides)
  5. Shake vigorously
  6. Autoclave for 1 h at 121 °C and let cool down
  7. After 24 h autoclave for a second time (for 1 h at 121 °C)
  8. Remove bigger particles and debris by centrifugation
  9. Filter through Whatmanfilter 595 (1/2, 320 mm) to remove residual particles
  10. Filter sterilize (PES membrane, pore size 0,22 µm)
  11. Store at 4°C – 10°C
  12. Make up to <span class='amount' data-volume='1000'>1000</span> ml with Milli Q water.
  13. Prepare aliquots and store them at -20 °C.
