Microbial Degradation of Anionic Synthetic Detergents

음이온계 합성세제의 미생물분해

A microbial strain capable of degrading ABS (alkyl benzene sulfonate) was isolated and identified as Pseudomonas caryophylli. During the incubation of the isolated bacterium in a synthetic effluent containing 10 ppm of ABS, the extents of removal of ABS, BOD and COD were 40％, 89％ and 71％, respectively. The degradability of ABS by pure culture with the isolated strain was twice higher than that of mixed culture with natural microflora. The biodegradability of some commercial detergents in Korea by the isolated organism was as follows: Hiti 46.2％, Kleenup 37.5％, No.1 29％, and OK 27.9％.

음이온계 합성세제인 ABS (alkyl benzene sulfonate)의 분해능이 우수한 균주를 자연계에서 분리하여 Pseudomonas caryophylli로 동정하였다. ABS 10 ppm을 함유한 인공폐수에서 분리균주를 배양시 ABS는 40％ 이상, BOD는 89％, COD는 71％ 감소되었으며 ABS분해능은 자연미생물군에 의한 혼합배양시의 2배 이상이었다. 분리균주에 의한 시판 합성세제의 분해율은 Hiti 46.2％, Kleenup 37.5％, No.1 29％, OK 27.8％이었다.
