特殊说明
383: DESULFOBACTERIUM MEDIUM
1. Solution A is sparged with 80% N2 and 20% CO2 gas mixture to reach a pH below 6 (at
least 30 min), then distributed in anoxic cultivation vials and autoclaved under the same
gas atmosphere. Solution B is autoclaved separately under 80% N2 and 20% CO2 gas
atmosphere. Solutions C and D are prepared under 100% N2 gas and filter-sterilized.
Solution E is autoclaved under 100% N2 gas. To complete the medium appropriate
amounts of solutions B to E are added to the sterile solution A in the sequence as
indicated. Final pH of the medium should be 7.0 – 7.2.
2. Note: Addition of 10 - 20 mg sodium dithionite per liter (e.g. from 5% (w/v) solution
freshly prepared under N2 and filter-sterilized) may stimulate growth of some strains at the
beginning. For transfers use 5 - 10% inoculum. Incubate all strains in the dark.
For DSM 2056: Replace pyruvate with 0.70 g/l Na-butyrate, 0.30 g/l Na-caproate, and 0.15
g/l sodium octanoate.
For DSM 3383: Replace pyruvate with indole as substrate. Dissolve 0.30 g of indole in 90
ml water by heating and shaking in a closed bottle under 100% N2 gas atmosphere,
autoclave, then add 7.00 ml of a sterile anoxic stock solution of NaCl (30% w/v) and 0.70
ml of a sterile anoxic stock solution of MgCl2 x 6 H2O (40% w/v). Store the indole-salt
solution in the dark. Reheat and shake before use. Add to sterile medium 30.00 ml/l of the
indole-salt solution in the beginning, and 2 x 30.00 ml/l during growth.
For DSM 3384: The vitamin solution of medium 120 is replaced with 1.00 ml/l of seven
vitamins solution of medium 503. Replace pyruvate with 0.40 g/l Na-benzoate and add
10.00 ml/l clarified rumen fluid (see medium 1310) as growth supplement. Initiation of
growth requires addition of freshly prepared sodium dithionite.
For DSM 4661: Replace pyurvate with resorcinol. During growth the culture is fed once
with the same amount of resorcinol.
For DSM 5091, DSM 9788: Replace pyruvate with 2.00 g/l malonic acid.
For DSM 7044, DSM 7120, DSM 7467, DSM 12567, DSM 13228, DSM 23484: Supplement
medium with 1.00 ml/l seven vitamins solution (see medium 503). Replace pyruvate with
0.40 g/l benzoate and 0.10 g/l yeast extract sterilized separately by filtration and add to
the autoclaved medium from anoxic stock solutions.
For DSM 8540: Replace pyruvate with 0.30 g/l p-hydroxybenzoate.
For DSM 9705: Replace pyruvate with 1.00 g/l Na-glycolate sterilized by filtration.
For DSM 12861, DSM 12883: Replace pyruvate with 1.00 g/l valeric acid.
For DSM 12888: Replace pyruvate with 1.10 g/l Na-butyrate and 1.10 g/l caproic acid.
For DSM 13036: Replace pyruvate with 1.00 g/l betaine.
For DSM 14454: Naphthalene dissolved in heptamethylnonane can be used as substrate
instead of pyruvate.
For DSM 15576, DSM 16219: Replace pyruvate with 1.00 g/l Na-caprylate and supplement
medium with 1.00 ml/l seven vitamins solution (see medium 503) added to the autoclaved
medium from an anoxic stock solution sterilized by filtration.
For DSM 17291: Replace pyruvate with 3.00 g/l Casamino acids.
For DSM 17477: Replace pyruvate with 1.90 g/l sodium glutamate monohydrate and 1.00
g/l yeast extract.
For DSM 21856: Replace pyruvate with 0.90 ml/l 1-butanol.
For DSM 28890: Replace pyruvate with 0.50 g/l yeast extract and 0.68 g/l sodium formate.
For DSM 100305, DSM 105015: Change amount of pyruvate to 2.20 g/l and add 0.10 g/l
yeast extract.
