토양에서 분리된 Cocobacilli B-17균의 Plasmid가 결정하는 Cadmium내성

Plasmid-Determined Cadmium Resistance in Cocobacilli Strain B-17 Isolated from Soil.

Cadmium resistant cocobacillus B-17 from soil was tolerated up to 1600ug/ml of cadmium at agar plate and the strain B-17 was able to grow at 600ug/ml of cadmium at liquid medium after the lag phase being prolonged with lengthening culture time. Optimal pH of the strain was shown at pH7.0. The elimination frequency of cadmium resistance by 10ug/ml of acriflavin was 28%, and by 20ug/ml of ethidium bromide was 47%, respectively.
