Mixed plastics were collected from Catalina Harbor on Catalina Island, CA. After sorting, polyethylenes were catalytically degraded into carboxylic diacids. These diacids are then upgraded by engineered strains of Aspergillus nidulans into structurally diverse secondary metabolites. Phase contrast micrographs show ample asperbenzaldehyde crystals in liquid culture medium containing polyethylene digest.

聚乙烯转化为真菌次级代谢产物

混合塑料是从加利福尼亚州卡塔利娜岛的卡塔利娜港收集的。分选后，聚乙烯被催化降解为羧酸二酸。然后，这些二酸被Aspergillus nidulans的工程菌株升级为结构多样的次级代谢产物。相差显微照片显示在含有聚乙烯消化物的液体培养基中有大量的曲霉苯甲醛晶体。
