| Abstract | The removing copper from CCA, CCFZ treated wood were tested with Tyromyces palustris. The shacking culture, solid culture, and stationary culture methods were tested to removal of copper in CCA, CCFZ treated wood. The steam pressure method and oxalic acid method were tested as pretreatment. To investigate of copper removal mechanism, the oxalic acid that produced by T. palustris and combination with copper was examined on stationary culture that contained CCA and CCFZ treated wood chips. Oxalic acid increased copper removing rate of T. palustris as pretreatment. Stationary culture had most removal effectiveness among the culturing methods. The removal rate of copper on bioreactor was 61% on 7 days. Copper-oxalate was detected on liquid culture, which show the oxalate from liquid of culture combined with copper from treated wood. It would be related to the removal of copper from treated wood by T. palustris. 갈색부후균 Tyromyces palustris를 이용하여 CCA, CCFZ처리 목재에서 구리를 제거하였다. 균에 의한 구리의 제거효율을 높이기 위한 전처리 방법으로서 증기압처리와 수산처리를 검토하였으며, 적정 배양 방법을 찾기 위하여 진탕배양, 고체배양, 정치배양에서 구리 제거율을 비교하였다. 전처리 방법에서, 증기압 처리만으로는 효과적인 구리제거가 불가능하였으며, 수산처리는 구리제거율은 낮았으나 수산처리 후 균처리를 하면 제거율이 향상되었다. 배양 방법에서는 정치 배양의 구리 제거효율이 높게 나타났다. 대량 배양을 위한 공기부양식 생물반응기에 의한 구리의 제거율은 7일 배양 이후 61%의 제거율을 보였다. T. palustris에 의한 구리제거기작을 탐색하기 위하여 배양액 중에 생성된 물질을 LC/Mass 분석 결과 T. palustris에서 분비되어진 수산과 방부처리 목재 중의 구리가 결합된 수산구리 착염체의 형성이 배양액 중에 존재함이 확인됨으로 균체 외 수산의 작용이 처리재의 구리제거에 크게 관여함이 밝혀졌다. |
