Description

Mutagenic effects, such as mortality, colony morphology, culture characteristic of Rhizopus oryzae irradiated by synchrotron soft X-ray, were studied preliminarily. The results show that the mutagenic effects of synchronous radiation soft-X ray on Rhizopus oryzae AS 3.3461 strain were obvious. Mortality curve appeared 'addle' shape and the lowest lethal rate was shown with dose of 0.72 kGy. Difference of colony morphology from original strain was observed. Lag phase of inocula shortened by 3h. Quantity of L-lactic acid and LDH specific activity increased by 25.6% and 95.8%, respectively, whereas ADH specific activity reduced 77.7%. (authors)
