Six different water bodies of different salinities and bacteria were set up to study the effects of microorganisms and salts on the degradation process of biodegradable polycaprolactone (PCL) spline. The experimental data for a 52-week period consistently indicate that both microorganisms and salts have an impact on the degradation process. PCL shows slow bulk hydrolysis in aseptic water and relatively rapid interfacial enzymatic degradation in bacteria-containing water however. The degradation rate of PCL in lab-prepared high-salinity seawater was noticeably higher than that in distilled water and low-salinity seawater, indicating a salt-driven acceleration of PCL hydrolysis. Because of the combined effects of factors such as the presence of bacteria, salinity, and external forces in the sea, PCL degrades fastest in natural seawater, losing 29.8% of its original weight in 52 weeks.

建立了六个不同盐度和细菌的不同水体，以研究微生物和盐对可生物降解的聚己内酯（PCL）花键降解过程的影响。52周的实验数据始终表明，微生物和盐都对降解过程有影响。然而，PCL在无菌水中显示缓慢的整体水解，而在含细菌的水中则显示相对较快的界面酶促降解。实验室制备的高盐度海水中PCL的降解速率明显高于蒸馏水和低盐度海水中的PCL降解速率，表明盐驱使PCL水解加速。由于海洋中细菌的存在，盐度和外力等因素的综合作用，PCL在天然海水中降解最快，损失29。
