[Development of growth medium from meat processing waste products and assessment of its properties].

New growth medium based on inedible substrate - meat processing waste products of slaughterhouses - was developed. New medium was characterized by physical, chemical, and biological properties using exacting and non-exacting microorganisms, as well as by periodical cultivation of Corynebacterium diphtheriae strain and obtaining the preparation of its antigens. The experimental medium provided the growth of chosen test-strains with typical properties.

[Properties of Corynebacterium diphtheriae cultivated in the medium prepared from inedible raw materials].

A nutrient medium for the cultivation of C. diphtheriae toxigenic strain was developed on the basis of raw materials unsuitable for use as foodstuffs and its main physico-chemical and cultivation properties were studied. The morphological, cultural, biochemical and toxigenic properties of C.
