Changes in the quantitative and functional characteristics of bacterioplankton under the influence of aqueous unmodified fullerene dispersions С60

The effect of aqueous unmodified fullerene C 60 dispersions (AFD) at a concentration of 5 mg/l on the total number and metabolic activity of heterotrophic river bacteroplankton has been 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 decreases the bactericidal activity of antibiotics. The stimulating effect of fullerene on the natural heterotrophic bacterioplankton, which we found out, casts doubt on the expediency of using AFD as a bacteriostatic agent.
