title: Degradation and turnover of extracellular DNA in marine sediments: ecological and methodological considerations.
abstract: Degradation rates of extracellular DNA determined in marine sediments were much higher than those in the water column. However, due to the high sediment DNA content, turnover times were much shorter in seawater. Results reported here provide new insights into the role of extracellular DNA in P cycling in marine ecosystems.
