[Soy hydrolysate-based nutrient media: development and study of biological properties].

By using the designed soy hydrolysate, the authors developed dry nutrient media that were analogues of trypticase soy broth, trypticase soy agar, and Eugon agar. The media showed a high sensitivity and a significant accumulative activity against test strains that belonged to different taxonomy groups and they were as good as the known Merck media in these parameters and in the number, size, and shape of colonies.
