Dissolve ingredients except cellobiose, sparge medium with 80% N2 and 20% CO2 gas mixture for 30 ? 45 min to make it anoxic. Then adjust pH to 7.0 - 7.2, distribute under same gas atmosphere in anoxic Hungate-type tubes or serum vials and autoclave. Cellobiose is added to the sterile medium from an anoxic 10% (w/v) stock solution prepared under 100% N2 gas and sterilized by filtration. Some strains can be adapted to cellulose as substrate using 10.00 g/l cellulose (Avicel or MN 301, MACHEREY-NAGEL). Note: A white precipitate forms after mixing the ingredients of this medium, but this has no negative effect on growth. | ||
