Changes in the Quantitative and Functional Characteristics of Bacterioplankton under the Influence of Aqueous Unmodified Fullerene С60 Dispersions

Resumo

The effect of aqueous unmodified fullerene C₆₀ dispersions (AFD) at a concentration of 5 mg/L on the total number and metabolic activity of heterotrophic river bacteroplankton was investigated. The stimulating effect of AFD on the number of bacterioplankton and on the activity of electron transport chains in its cells is shown. It is established that, in the presence of AFD, the bactericidal activity of antibiotics decreases. The stimulating effect of fullerene on the natural heterotrophic bacterioplankton, which we discovered, casts doubt on the expediency of using AFD as a bacteriostatic agent.
