我们调查了淡水样品中生物降解塑料上生物膜的形成。聚（3-羟基丁酸酯-co-3-羟基己酸酯）（PHBH）在淡水样品中孵育后被生物膜覆盖。对PHBH膜上形成的生物膜的细菌群落的下一代测序分析揭示了伯克霍尔德菌目的优势。此外，大多数生物膜中的优势菌属为嗜酸菌属和Undibacterium属。28株PHBH降解菌中有25株归属于嗜酸菌属，另外3株归属于Undibacterium和Chitinimonas属。这些结果表明，在生物膜中的伯克霍尔德菌作为PHBH膜的降解剂的功能。
We investigated biofilm formation on biodegradable plastics in freshwater samples. Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH) was covered by a biofilm after an incubation in freshwater samples. A next generation sequencing analysis of the bacterial communities of biofilms that formed on PHBH films revealed the dominance of the order Burkholderiales. Furthermore, Acidovorax and Undibacterium were the predominant genera in most biofilms. Twenty-five out of 28 PHBH-degrading isolates were assigned to the genus Acidovorax, while the other three were assigned to the genera Undibacterium and Chitinimonas. These results demonstrated that the order Burkholderiales in biofilms functions as a degrader of PHBH films.
