【 摘 要 】

It is known that the immobilization of microorganisms on carriers of various natures increases their safety. The inorganic matrices used were sodium carboxymethyl cellulose, technical brand “KMC 85/500;” colloidal silicon dioxide in the form of a commercial preparation, “Polysorb;” and the sodium form of montmorillonite from the Podgorenskoye deposit in the Voronezh region. Bacterial cells were immobilized by adding Lysobacter sp. solid sterile carrier with constant mechanical stirring in a “carrier/biomass” ratio equal to 1: (2–4). During the experiment, it was found that the mineral montmorillonite is a promising material for the immobilization of bacterial cells in order to obtain biocompositions based on them, since a positive trend in the preservation of bacterial cells was revealed.
