The influence of controlled thermophilic composting of PLA bio-composites on bacterial community
Original language description
Polylactic acid (PLA) is one of the most widespread industrial-scale products of biodegrad- able polymers with fast growing commercial applications. In this study, we assessed the bio- degradation of PLA and modified PLA films with eco-friendly plasticizers acetyl tributyl citrate (PLA-ATBC), calcium carbonate (CaCO3, i.e., PLA-ATBC@CaCO3), and lignin-coated cel- lulose nanocrystals (LCNC, PLA-ATBC@LCNC) under controlled thermophilic aerobic condi- tions. The biodegradation of PLA films was evaluated according to the standard method by analysis of evolved carbon dioxide. The bacterial communities attached on different PLA films were characterized by 16S rRNA sequencing. After two months, the PLA-ATBC@CaCO3 film was 100% degraded, which corresponded to the highest bacterial abundance in bioreactors com- pared to PLA, PLA-ATBC and PLA-ATBC@LCNC films. The abundance of bacterial populations (>0.01) showed minor changes over 3 months, whereas Thermogemmatispora, Thermoflavifilum and Acidicaldus (not in PLA-ATBC-CaCO3) were highly abundant in all treatments. The bacterial populations of low-abundance (<0.001) dynamically changed in PLA-ATBC@CaCO3 samples, Geobacillus found potential PLA degrader and others, Thermobispora, Rhodoplanes, Thermoleophilum, Filomicrobium and Roseisolibacter.
