[Breeding of arachidonic acid producting strain by ion implantation].
With ion implantation, a high-yield arachidonic acid producting strain(Mortierella alpina) I49-N18 was selected, whose biomass was 30.80 g/L. The lipid component of biomass was 25.8%, in which AA content was 45.37%. The results showed that selected high-yield strain was steady on 250 L fermentor, whose AA yield was 4.0 g/L.
