Abstract

In this study, we investigated the interaction of submicron-sized bioplastics with environmentally and clinically important bacteria under seawater and sediment conditions. To examine the relationship between submicron-sized bioplastics and bacteria in seawater and sediment, we focused on the bacterial activation and their biochemical key events toward the protein, carbohydrate, lipid, and antioxidant response. In addition, culture-dependent biofilm formation on submicron-sized bioplastics and their characterization was performed. The results indicated that selected bacteria increased their viability both in seawater and sediment with the submicron-sized bioplastics in that the bioplastics decreased their mass at the level of 10–23%. However, the activation level and mechanism affected the polymer type, bacteria, and environmental media, and submicron-sized bioplastics promoted biofilm formation with enhancing basophilic characteristics of biofilms.

摘要

在这项研究中，我们研究了亚微米尺寸生物塑料与海水和沉积物条件下对环境和临床具有重要意义的细菌之间的相互作用。为了检查亚微米尺寸生物塑料与海水和沉积物中细菌之间的关系，我们集中于细菌活化及其对蛋白质，碳水化合物，脂质和抗氧化剂反应的生化关键事件。另外，进行了亚微米尺寸生物塑料上依赖于培养物的生物膜形成及其表征。结果表明，选定的细菌在亚微米级生物塑料中增加了在海水和沉积物中的生存力，因为生物塑料的质量降低了10％至23％。但是，激活水平和机制会影响聚合物的类型，细菌和环境介质，
