Medium for Clostridium estertheticum subsp. laramiense DSM 14864

This strain uses the standard medium without modifications.

Growth conditions: more than 14 days anaerobic 10 °C

Equipment needed: Autoclave Hungate tubes Filter
Compound Amount Unit Conc. [g/L] Conc. [mM]
Ground beef

1 Use lean beef or horse meat. Remove fat and connective tissue before grinding. Mix meat, water and NaOH, then boil for 15 min with stirring. Cool to room temperature, skim fat off surface, and filter, retaining both meat particles and filtrate. To the filtrate add water to a final volume of 1000 ml, and then add:

L-Cysteine HCl , add to make medium anoxic 0.5 g 0.5 3.172
Agar , if required 15.0 g 15 44.599
2 In some cases (as indicated in the catalogue) the addition of Haemin and Vitamin K1 or Vitamin K3 is necessary. Add to 1000 ml of medium after autoclaving: and either or
Haemin solution 10.0 ml - -
Vitamin K1 solution , alternative 10.0 ml - -
Vitamin K3 solution 10.0 ml - -
3 To make medium anoxic boil it, cool under 100% N2 gas atmosphere, add 0.5 g/l L-cysteine hydrochloride and adjust pH to 7.0. Dispense under same gas atmosphere 7 ml medium into Hungate-type tubes (for strains demanding meat particles put those first into the tube (use 1 part meat particles to 4 or 5 parts fluid)). Autoclave at 121°C for 30 min. For agar slants use 15.0 g agar per 1000.0 ml medium.
