采用多孔陶瓷作为苯酚降解菌的载体，在紫外辐射下对苯酚进行生物降解。结果表明，紫外辐射没有影响微生物的生物活性。相比单一的生物降解，在紫外辐射下苯酚生物降解时，苯酚矿化程度可以提高2.1倍。通过分子生物学分析证明，在多孔陶瓷内部的生物膜群落与没有经过紫外辐射的微生物群落几乎一致。这表明多孔陶瓷可以保护微生物群落不受紫外辐射的影响。

Porous ceramics were used as carriers of phenol degrading bacteria for phenol biodegradation. Experimental results suggest that the biodegradability of the phenol degrading bacteria exposed to UV irradiation was the same as that of the unexposed bacteria. But their phenol mineralization degree was increased by 2.1 times when UV irradiation was coupled with biodegradation compared with biodegradation alone. Molecular biological analysis documents that the microbiological community inside macro-pores exposed to UV irradiation was consistent with the one unexposed to UV irradiation. Survival of bacteria inside macro-pores demonstrated that being in a microbiological community inside the porous ceramic carriers protected the bacteria from UV-light toxicity.
