EFFECTS OF ULTRAVIOLET LIGHT AND NUCLEIC ACID DERIVATIVES ON THE REPRODUCTIVE RATE OF AZOTOBACTER

Azotobacter의 증진율에 미치는 자외선 및 nucleic acid derivatives의 영향

Azotobacter is isolated from soil and its purified species is identified as A. chroococcum. The survival rate of Azotobacter irradiated with UV light is measured, and the reproductive rates of the survivals are calculated. In general, not only the survival rate, but also the length of the generation time of the survival progeny is inversely proportional to the irradiated dose of UV light. The reproduvtive rate of Azotobacter is increased with the exogeneous treatment of nucleic acid derivatives.
