Clothes and fishing nets that are made of nylon often end up in landfill or dumped in oceans, but a new way to break down the ...

Led by Dr Neil Dixon, the team utilised the bacterium Pseudomonas putida, renowned for its resilience and adaptability, to process complex waste streams into bioplastics and even therapeutic proteins.

Nylon is a common plastic, but it is difficult to recycle. A genetically modified bacterium is supposed to make it possible.

将化学水解与生物催化相结合，有望实现 PA 复杂水解产物的代谢汇集，并转化为高附加值产品，避免繁琐的纯化步骤。但目前缺乏能将 PA 水解产物转化为高附加值产品的微生物宿主，虽然部分微生物能代谢 PA 相关单体或低聚物，但大多局限于特定底物，且未与产品形成关联。恶臭假单胞菌 P. putida KT2440 虽能代谢多种塑料单体并生产高附加值化合物，但无法代谢 PA 相关底物，限制了其在 PA ...
