聚己内酯（PCL），聚（乙烯醇）（PVAl）和它们的共混物已经在从工业堆肥的生活垃圾中分离的微生物的纯菌株的存在下培养。在这项工作中使用的条件下，纯聚己内酯（PCL）薄膜完全吸收超过600-800小时的时间。纯PVAl即使暴露时间长得多也不会降解。出乎意料的是，在这些微生物的存在下，即使富含PCL的共混物也没有改变（重量损失、氧吸收也没有微生物生长）。已经表明，PVAl不会使菌株失活，也不是导致这种失活的原因。PVAl即使在孵育介质中少量存在时，也吸附在PCL或共混物膜的表面上; PCL然后不可接近微生物。
Polycaprolactone (PCL), poly(vinylalcohol) (PVAl) and their blends have been incubated in the presence of a pure strain of micro-organisms isolated from an industrial compost for house-hold refuse. In the conditions used in this work, pure polycaprolactone (PCL) films are completely assimilated over periods of 600–800 h. Pure PVAl is not degraded even for much longer exposure times. Unexpectedly, the blends, even PCL rich, are not altered (neither weight loss, oxygen uptake nor micro-organism growth) in the presence of these micro-organisms. It has been shown that inactivation of the strain by PVAl does not occur and is not responsible for this. PVAl, even when present in small amounts in the incubation medium, adsorbs on the surface of PCL or blend films; PCL is then inaccessible to micro-organisms.
