摘要

在这里，我们证明了微生物合成的聚[45 mol%乳酸(LA)-co-3-羟基丁酸盐（3HB）] （LAHB）在海水中的良好分解，这被认为是塑料生物降解的一个严峻条件。这提供了LAHB在海洋不可生物降解聚乳酸（PLA）上的生态友好效用。因此，LAHB可以被认为是一种先进的版本，共享可生物降解的3hb -均聚物和广泛使用的PLA的有益性能。

Seawater biodegradation of a microbial lactate-based polyester (LAHB) as an advanced version of non-degradable polylactide.

Here, we have demonstrated the good decomposition of microbially synthesized poly[45 mol% lactate (LA)-co-3-hydroxybutyrate (3HB)] (LAHB) in seawater, considered as a severe condition for plastic biodegradation. This provides the ecofriendly utility of LAHB over marine non-biodegradable polylactide (PLA). Accordingly, LAHB can be recognized as an advanced version sharing the beneficial properties of the biodegradable 3HB homopolymer and the widely used PLA.
