Selection of Pycnoporus cinnabarinus strains for laccase production.
A comparison of Pycnoporus cinnabarinus strains for laccase production was carried out. A dikaryotic strain, I-937 strain, producing a high level of laccase (9500 U l(-1)) was selected. The study of the life cycle in vitro of this dikaryotic strain led to isolation of monokaryons. Forty-eight monokaryotic strains were isolated and screened for laccase production. One of these strains, ss3, produced a higher level of laccase than the parental strain I-937. The maximum production reached 29000 U l(-1) in medium supplemented with ferulic acid.
