Abstract
Abstract Laccase production by the strain Pycnoporus cinnabarinus ss3 was studied in a solid-state culture on sugar-cane bagasse using chemical compounds as inducers (ethanol, methanol, veratryl alcohol and ferulic acid). Laccase productions were about 5- to 8.5-fold higher than non-induced cultures. Liquid-culture experiments with 14C-labeled ethanol were conducted. Ninety-eight percent of the initial amount of 14C from ethanol was recovered as 14CO2, 14C-biomass and soluble 14C-compounds (mainly ethanol). The amount of 14C in the biomass was only 6.8% of the total carbon consumed by P. cinnabarinus, in absence of maltose, representing only 2.8% of added ethano...
