摘要：

Various thermophilic actinomycetes were screened for their ability to degrade a high melting point, aliphatic polyester, poly(tetramethylene succinate) (PTMS), at 50 degreesC. By using the clear zone method, Microbispora rosea, Excellospora japonica and E. viridilutea were found to have PTMS-degrading activity. In a liquid culture with 100 mg PTMS film, M. rosea subsp. aerata IFO 14046 degraded about 50 mg film sample after 8 days. Degradation at the amorphous regions of the PTMS film was observed by scanning electron microscopy. This strain was also able to completely degrade poly(epsilon -caprolactone).
