Abstract

The contamination of wastewater by microplastic particles (MPs) is anunresolved environmental problem. In order to resolve this problem, aconcept is developed for the microbial remediation of MPs. To realize thisconcept, degradable block copolymers are required, which adhere on MPsurfaces and contain segments of carbohydrate moieties (here galactose) forthe attraction of degrading microbes and accelerated biofilm formation.Therefore, in this study, a versatile synthesis route for amphiphiliccarbohydrate block copolymers from poly(d,l-lactic acid) (PLA) and galactosemoieties is presented. The properties of the block copolymers are investigatedby thermal analysis, as well as regarding their colloidal properties, theiradhesion behavior on MP surfaces, and their potential for support ofmicrobial growth (usingLacticaseibacillus zeae).
