Filtration,identification and physicochemical properties of fungus which produce red pigment
In this article,we choose 20 strains with filtration of basic culture medium,initial filtration and refiltration of those strains in order to find one high-yield strain which produces red pigment.We get GG-6j whose inside cell OD is 0.53,outside cell OD is 0.29,the highest cell OD of all the strains with the highest growth activity.It belongs to Fusarium by identification.Its properties indicate that the red pigment from GG-6j strain dissolves very easily in organic solvent,it can also endure high temperature.The maximum absorption wavelength in the range of visible light is 520 nm.
