Phellinus robustus produced both laccase (700-4,000 U l(-1)) and manganese peroxidase (MnP) (1,000-11,300 U l(-1)) in fermentation of nine food wastes, whereas Ganoderma adspersum produced only laccase (600-34,000 U l(-1)). Glucose provided high laccase and MnP activity of P. robustus but repressed enzyme production by G. adspersum. Ammonium sulphate and ammonium tartrate increased the P. robustus laccase yield (3-fold), whereas the accumulation of MnP was not enhanced by additional nitrogen.
