[Ion beam implantation in breeding efficient degradation bacteria].
Sphingomonas sp. AN1 was mutagenized and breeded by N+ implantation, mutants capable of degrading anthrancene was obtained. The research review that the degrading rate increased by 29.3% and 36.2% while the mutagenized rate was 80% - 100% and 60% - 80%. In addition, the maximum concentration of enduring anthracene reached 300mg/L and 400mg/L. Their heritance stability were examined for fifteen transfers. Among these strains, two strains,AN815-3 and AN315-5S,showed predominant character of survival ability and degrading activity. Their rate of degrading anthrancene reached 73% and 75% respectively. Effect of positive mutagenesis is evident.
