Interactions of extracellular DNA with aromatized biochar and protection against degradation by DNase I
Abstract
The adsorption of eDNA on aromatized biochar was irreversible. π-π interaction was involved in eDNA adsorption. Increasing solution ionic strength significantly increased eDNA adsorption. Biochar-bound eDNA could be partly degraded by nuclease. Biochar-bound nuclease almost lost the degradability to eDNA.
