Breeding of Arachidonic Acid Producting Strain by Ion Implantation
离子注入花生四烯酸产生菌诱变选育

With ion implantation,a high-yield arachidonic acid producting strain(Mortierella alpina)I49-N18 was selected,whose biomass was 30.80g/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 250L fermentor,whose AA yield was 4.0g/L.
