| Microorganisms capable of degrading poly(butylene succinate-co-butylene adipate) (PBSA) were isolated from 40 soil samples such as landfill site soil, cultivating soil and activated sludge soil from 20 different sites in Korea by using the enrichment culture and the clear zone test at $37^{circ}C$. Based on the 16S rDNA sequences, the isolated bacterium was identified to be Streptomyces sp. PBSA-1. Morphological and cultural characteristics were employed for the identification of the isolated fungi and they were proved to be Aspergillus fumigatus PBSA-2 and Aspergillus fumigatus PBSA-3. The PBSA degradation activity of the isolated microorganisms was enhanced through the serial acclimation in PBSA plate medium. The PBSA degrading microorganisms appeared to be highly active for the PBSA degradation in that 83% of PBSA was degraded by Streptomyces sp. PBSA-l, and 65% and 75% of PBSA was mineralized by A. fumigatus PBSA2 and A. fumigatus PBSA-3 respectively during 40 days of the modified Sturm test. |
