海洋沉积物中测定的胞外DNA降解速率远高于水体中的降解速率。然而，由于沉积物DNA含量高，周转时间在海水中要短得多。这里报道的结果提供了新的见解在海洋生态系统中的P循环细胞外DNA的作用。
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.
