title: [Production of stable Bacillus thuringiensis suspensions in an electromagnetic apparatus].
abstract: The experiment demonstrated the podibility of obtaining stable suspensions of B. subtilis, a microorganism used as an experimental model, in an electromagnetic apparatus with a bilateral inductor. The optimum conditions of obtaining such suspensions were chosen, these conditions excluding the inactivation of the bacteria used as a model in the course of the process. Suspensions containing 75% of culture fluid were shown to have the highest stability during prolonged storage. Suspensions on the basis of the crystal-forming bacteria B. thuringiensis sp. kurstaki, strain Z-52, used in the production of entomopathogenic preparations and characterized by high stability and good viability in the process of storage were prepared under the selected conditions. The apparatus used in these experiments was recommended for use in the technology of the production of biopreparations of the basis of the above-mentioned bacteria.
