18 distinct modifications were found.
Change amount of pyruvate to 2.20 g/l and add 0.10 g/l yeast extract.
Naphthalene dissolved in heptamethylnonane can be used as substrate instead of pyruvate.
Replace pyruvate with 0.30 g/l p-hydroxybenzoate.
Replace pyruvate with 0.50 g/l yeast extract and 0.68 g/l sodium formate.
Replace pyruvate with 0.70 g/l Na-butyrate, 0.30 g/l Na-caproate, and 0.15 g/l sodium octanoate.
Replace pyruvate with 0.90 ml/l 1-butanol.
Replace pyruvate with 1.00 g/l valeric acid.
Replace pyruvate with 1.00 g/l betaine.
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.
Replace pyruvate with 1.00 g/l Na-glycolate sterilized by filtration.
Replace pyruvate with 1.10 g/l Na-butyrate and 1.10 g/l caproic acid.
Replace pyruvate with 1.90 g/l sodium glutamate monohydrate and 1.00 g/l yeast extract.
Replace pyruvate with 2.00 g/l malonic acid.
Replace pyruvate with 3.00 g/l Casamino acids.
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.
Replace pyurvate with resorcinol. During growth the culture is fed once with the same amount of resorcinol.
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.

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.
