| Popis: | This study evaluated the raw materials for spawning Perenniporia fraxinea, to eliminate urushiol. The growth rates of spawns on grains of millet, brown rice, and wheat were 4.92±0.05, 2.20±0.03, and 1.93±0.03 mm/day, respectively, and the laccase activity was 0.86±0.02, 0.04±0.01, and 0.01±0.00 U/mL, respectively. These observations revealed millet as the most appropriate grain for spawn production in terms of growth rate and enzyme activity. inoculation of lacquer tree (Rhus verniciflua Stokes) stem bark with millet spawns of P. fraxinea resulted in a reduction of its urushiol contents, up to 86.6% on the third day and up to 98.5% on the seventh day. The optimal period of cultivation to eliminate urushiol was three days with 68% of residual flavonoids and 42% of phenolic components. When compared to the product cultivated from liquid spawn, the millet spawn reduced the cultivation period from 10 days to 3 days for eliminating urushiol. |
