Abstract EN
Various culture parameters were optimised for laccase synthesis by Trametes pubescens MB89, including pH, carbon source, nitrogen source, lignocellulosic supplements, and reported inducers.
Glucose, in conjunction with a complex nitrogen source at pH 5.0, resulted in the highest laccase yield.
Adding ethanol, copper, or 2,5-xylidine prior to inoculation further improved laccase concentrations.
The addition of 2,5-xylidine was further investigated with multiple additions applied at varying times.
This novel application substantially improved laccase production when applied regularly from inoculation and during the growth phase, and also countered glucose repression of laccase synthesis.
Single and multiple factor changes were studied in three distillery wastewaters and a wine lees.
A synergistic increase in laccase synthesis was observed with the addition of glucose, copper, and 2,5-xylidine.
Single addition of 2,5-xylidine proved most beneficial with distillery wastewaters, while copper addition was most beneficial when using the wine lees as a culture medium.
