The results of the comparative study of different substrates prepared from foodstuffs and inedible raw materials and intended for use as the nutrient base of a medium for cultivating the organisms of the genera Bacteroides and Fusobacterium have demonstrated that commonly used nutrient bases prepared from meat, fish, casein and inedible animal blood (blood substitutes) are suitable for this purpose. The dried nutrient base prepared from the mixture of outdated blood substitutes (hydrolysin and casein hydrolysate) (see text for Russian letters) has been found to ensure the optimum growth of Bacteroides and Fusobacterium.
