Laccase and Manganese Peroxidase Activities of Phellinus Robustus and Ganoderma Adspersum Grown on Food Industry Wastes in Submerged Fermentation

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.
