培养基:DSM Medium 110: CHOPPED MEAT MEDIUM WITH CARBOHYDRATES
Ground beef (fat free) 500g
Distilled water 1000ml
NaOH 1 N 25ml
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:
Casitone 30g
Yeast extract 5g
K2HPO4 5g
Na-resazurin solution (0.1% w/v) 0.5ml
D-Glucose 4g
Cellobiose 1g
Maltose 1g
Starch (soluble) 1g
To make medium anoxic boil it, cool under 100% N2 gas atmosphere, add 0.5 g/l Lcysteine 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 121C for 30 min. For agar slants use 15.0 g agar per 1000.0 ml medium.
In some cases (as indicated in the catalogue) the addition of Haemin and Vitamin K1 or Vitamin K3 is necessary. Add to 1000.0 ml of medium after autoclaving:
Haemin solution (see below) 10ml
Vitamin K1 or Vitamin K3 solution (see below) 10ml
Haemin solution:
Dissolve 50 mg haemin in 1 ml 1 N NaOH; make up to 100 ml with distilled water and filter sterilize. Store refrigerated.
Vitamin K1 solution:
Dissolve 0.1 ml of vitamin K1 in 20 ml 95% ethanol and filter sterilize. Store refrigerated in a brown bottle.
Vitamin K3 solution:
Dissolve 5 mg/ml of vitamin K3 in 95% ethanol, dilute to 0.05 mg/ml in water and filter sterilize. Store refrigerated in a brown bottle.
For DSM 22787 supplement medium after autoclaving with 50 ml/l of anoxic sterile horse serum.
For DSM 100320 adjust pH of medium to 7.5–8.0.
For DSM 103060 adjust pH of complete medium to 7.5.
