Directions
Suspend 25.00 grams in 1000 ml purified/distilled water. Heat if necessary 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
HiVeg™ peptone is the principal source of organic nitrogen while HiVeg™ extract, solid provides carbohydrates, vitamins, organic nitrogen compounds and salts. Sodium chloride maintains osmolality of the medium.
H.S. Vaccine HiVeg™ Medium (Standard Nutrient HiVeg™ Broth) is prepared by using vegetable peptones in place of animal based peptones which make the media free of BSE/TSE risks.
Type of specimen
Isolated Microorganism.
