두 Streptomyces Strains 에 의한 다핵 방향족 탄화수소화합물의 분해

Abstract

The purpose of this study was to investigate the degradation abilities of polynuclear aromatic hydrocarbon (PAHs; anthracene, phenanthrene, benzo(a)pyrene) compounds using Streptomyces hals- tedii scabies SAI-36, Streptomyces avendulas SA2-14, and Streptomyces badius (ATCC 39117, con- trol group). Benzo(a)pyrene and anthracene showed a the degradation ability of 99.5% and 99.2% respectively by Streptomyces lavendulas SA2-14. Benzo(a)pyrene showed the degradation ability of 98.0% by Streptomyces halstedii scabies SAl-36. Anthracene showed the lowest degradation ability of 47.7% by Streptomyces badius(ATCC 39117). Benzo(a)pyrene and phenanthren showed the highest degradation abilities of 71.7% and 78.8% respectively. The results suggested that two experimental strains denionstrated superior abilities above the control group in degradation of PAHs compounds and Streptomyces lavendulas SA2-14 was the superior strain between the two experimental strains. The results also proposed the possibility of the use of actinomycetes in the degradation of non-degradable materials. These results were consistent with previous research results that Streptomyces lavendulas SA2-14 was the best strain in degradation ability of lignin, decoloration abilities of different dyes, different enzyme production abilities and degradation abilities of phenol compounds. It is suggested that more basic research is needed for actinomycetes to be used as a biological degradation.
