Biodegradation of polyethylene glycols (PEGs) of up to 13,000 to 14,000 molecular weight has been shown to be performed by a river water bacterial isolate (strain JA1001) identified as Pseudomonas stutzeri. A pure culture of strain JA1001 grew on PEG 1000 or PEG 10000 at 0.2% (wt/vol) as a sole source of carbon and energy with a doubling time of 135 or 150 min, respectively. Cultures metabolized 2 g of polymer per liter in less than 24 h and 10 g/liter in less than 72 h. The limit of 13,500… CONTINUE READING
