Abstract excerpt
Ultraviolet and HNO2 were selected as the mutagens to perform the single factor and multi-factor induction mutation towards Candida utilis CR-001. Six mutant strains which possessed high heavy metal removal efficiency and high resistance to Cr6+ were obtained through combined induction with UV and HNO2. After they were subcultured for 10 generations, the diameter of bacteriostatic circle of CRC2811-1 and CRC7-2...
