Abstract
Lactobacillus and Streptococcus are cultured by special process steps to derive by controlled transmutation a strain of organisms having high tolerance to acidity above 1.5%, and are tolerant to metallic salts such as cobalt carbonate which tend to poison such organisms by limiting growth. The organisms are cultured in a transfer process from starter organisms that tend to clump in the presence of metallic ions to develop the improved strain which does not clump when cultured in the presence of metallic salts thereby permitting increased production. A characterizing feature of the resulting transmuted organisms therefore is the freedom of a tendency to clump in the presence of the cobalt ion, a feature uncharacteristic of the starting organisms. The organisms are useful for enhancing animal and plant growth.
