Abstract The research objective of this study was to verify the effectiveness of selected rhizosphere strains in accelerating the biodegradation of plastics in cultivated soil. The study was a continuation of experiments conducted in compost soil. The experiments confirmed the ability of the two bacteria and fungi strains in biodegradation of polylactide (PLA) and polyethylene terephthalate (PET). The combination of these microorganisms with some tested plant species increased the microbial population in the soil and, at the same time, degradation of the plastic films. The presence of the microorganisms in soil together with PLA reduced the soil pH value. The significant degradation changes of polymers were observed in the presence of S. plymuthica in both compost and cultivated soil. The presence of 155 genes related to xenobiotics biodegradation and removal was demonstrated after sequencing of the genome of this bacterium. These results can be used to develop an effective method for remediating plastic wastes in soils and landfills.

在微生物和植物的参与下，塑料 PLA 和 PET 在栽培土壤中的生物降解

摘要 本研究的研究目的是验证选定的根际菌株在加速栽培土壤中塑料生物降解方面的有效性。该研究是在堆肥土壤中进行的实验的延续。实验证实了这两种细菌和真菌菌株在生物降解聚丙交酯 (PLA) 和聚对苯二甲酸乙二醇酯 (PET) 方面的能力。这些微生物与一些经过测试的植物物种的结合增加了土壤中的微生物数量，同时增加了塑料薄膜的降解。土壤中微生物与 PLA 一起存在降低了土壤 pH 值。在堆肥和栽培土壤中，在 S. plymuthica 存在下观察到聚合物的显着降解变化。在对该细菌的基因组进行测序后，证实存在 155 个与异生物质生物降解和去除相关的基因。这些结果可用于开发一种有效的方法来修复土壤和垃圾填埋场中的塑料废物。
