| Abstract: | The white rot fungus Ganoderma, lucidum Karst was treated by UV radiation and ultra high pressure respectively. The mutagenic effect caused by ultra high pressure was bigger than that of UV radiation. The highyielding mutants G1502 and G2001 were obtained by ultra high pressure treat and fermentation screening. The laccase activity of G1502 was increased 2.83 times than that of original strain, moreover the incubated time that it reached its largest enzyme activities was 1 d shorter. The largest enzyme activity of mutant G2001 was increased 0.89 times higher than that of original strain, and its incubated time was decreased 3 d. |
| Keywords: | UV radiation ultra high pressure laccase Ganoderma lucidum Karst |
