[Biotransformation of lignocellulse by the fungi Pleurotus floridae (Fries) Kummer and Phellinus igniarius (Linnearus:Fries) Quelet--the pathogens of white rot in trees].
The peculiarities of lignocellulose biotransformation by white-rot fungi Pleurotus floridae and Phellinus igniarius during their solid-state fermentation of wastes of oil-bearing crops processing has been studied. The dynamics of oil-bearing crops processing wastes bioconversion has been studied. It has been marked that P. floridae utilized 20% cellulose and lignin during 9 weeks and 40% lignin and 30% cellulose during all period of fermentation (19 weeks). The fungus P. igniarius utilized mainly cellulose (40% cellulose and 24% lignin in 19 weeks). Lignin-degradative capacity of P. floridae (KL = 0.57) and P. igniarius (KL = 0.34) has been quantitatively estimated. The degradation of plant biopolimers corresponded to the production of ligninolytic (laccase, Mn(2+)-dependent peroxidase,) and cellulolytic (CMC-cellulase) enzymes. The component and isoenzyme content of ligninolytic enzyme complex of fungi Pleurotus floridae and Phellinus igniarius has been determined.
