RESUMO
AIMS: We report the identification of the bisphenol A (BPA) biodegradability in Streptomyces sp. strain isolated from river water. METHODS AND RESULTS: The water samples spiked with BPA (1 mg l(-1)) and the culture solution of Streptomyces sp. strain were placed at 30 degrees C for 10 days and were analysed by high-performance liquid chromatography. A half-life for BPA degradation was between 3 and 4 days. The removal rate of BPA was >90% for 10 days. CONCLUSIONS: These results show that the Streptomyces sp. strain isolated from river water has high BPA degradability. SIGNIFICANCE AND IMPACT OF THE STUDY: To our knowledge, this is the first report of BPA degradation by Streptomyces sp. strain.

A 39-year-old male was admitted to our ICU following traffic accident. The major symptoms were short breathness and unconsciousness due to cerebral hemorrhage. He was treated by mechanical ventilation which delayed the diagnosis of traumatic diaphragmatic hernia. On the 6 day after traffic accident we performed thoracotomy and repaired ruptured diaphragm. It was difficult to diagnose the patient as diaphragmatic hernia who was treated by mechanical ventilation.
