The influence of few-layer graphene on the physiological activity of spores of the rhizosphere culture B. subtilis sp.

The article presents the results of a study of the effect of few-layer graphene obtained under conditions of self-propagating high-temperature synthesis from cellulose on the physiological activity of the rhizosphere spore culture of B. Subtilis sp. It was found that few-layer graphene, as well as a dextrin/few-layer graphene composite, have a beneficial effect on the physiological activity of the rhizosphere spore culture of B. Subtilis sp. After 270 days of cultivation, the number of viable cells of Bacillus subtilis sp. increased 4-fold in the presence of few-layer graphene, and 5-fold in the presence of a dextrin/few-layer graphene composite compared to the initial concentration. The obtained data indicate the promise of using few-layer graphene to stimulate the physiological activity of bacterial cultures, which can make few-layer graphene a useful modifying additive to agricultural soil.
