Directions

Suspend 31.0 grams in 1000 ml purified/distilled water. Heat to boiling to dissolve the medium completely. Dispense into tubes or flasks as desired. Sterilize by autoclaving at 15 lbs pressure (121°C) for 15 minutes.

Principle And Interpretation

Soyabean Casein Digest Medium with 0.1% Agar is used for culturing organisms especially anaerobes from root canals, blood and other clinical samples. Inclusion of agar to this medium is useful for isolating anaerobic oral Vibrio's (1) and also anaerobic organisms causing nasal sinusitis (2).

Soyabean HiVeg™ Medium w/ 0.1% Agar is prepared by using vegetable peptones in place of animal based peptones which make the media free of BSE/TSE risks. HiVeg™ hydrolysate and soya peptone supplies nitrogenous and carbonaceous compounds, trace minerals etc. Dextrose serves as a source of fermentable carbohydrate for the energy production. Sodium chloride maintains osmotic balance while Dipotassium phosphate provides buffering capacity. Small percentage of agar helps in creating moderately anaerobic condition in the depth of the medium.
