PCBs를 분해하는 Pseudomonas sp. P20 균주의 pcbC gene이 재조합 된 E. coli CK1092 균주를 이용하여 2,3-dihydroxybiphenyl dioxygenase 생산에 미치는 배양조건을 검토하였다. E. coli CK1092를 2% sucrose가 포함된 LB 배지를 기본배지로 하여 질소원, 금속이온 등의 영향을 조사한 결과,
To obtain higher yield of 2,3-dihydroxybiphenyl(2,3-DHBP) dioxygenase by recombinant E. coli CK1092 carrying pcbC gene of Pseudomonas sp. P20, the environmental and physiological factors were investigated and the cultural conditions using jar fermentor were studied. E. coli CKl092 was grown in LB medium supplemented with 2% sucrose, as a basal medium. The effect of various metal ions on the enzyme production was investigated. In particular, the enzyme production increased in the presence of
