Influence of the Cultivation Conditions on Ligninolytic Enzyme Production in Pleurotus Pulmonarius
The highest level of laccase activity (391 Ul–1), as well as significant Mn-oxidizing peroxidases production, were found in solid-state culture with grapevine sawdust as the carbon source. After purification of extracellular crude enzyme mixture of Pleurotus pulmonarius, grown in the medium with the best carbon source (grapevine sawdust), three peaks of laccase activity were noted. The results ...
متن کاملDynamics of Ligninolytic Enzyme Production in Ganoderma Applanatum Depending on Cultivation Type
Ganoderma applanatum belongs to the group of white-rot fungi, due to a well-developed ligninolytic enzyme system. White-rot fungi have attracted great scientific attention in recent years, especially with respect to their enzymatic potential for the bioremediation of persistent pollutants. Contrary to G. lucidum, which medicinal properties, as well as ligninolytic enzyme system have been extens...
متن کاملBioremediation of Direct Blue 14 and Extracellular Ligninolytic Enzyme Production by White Rot Fungi: Pleurotus Spp.
In the present investigation, four species of white rot fungi (Pleurotus), that is, P. flabellatus, P. florida, P. ostreatus and P. sajor-caju were used for decolorization of direct blue 14 (DB14). Among all four species of Pleurotus, P. flabellatus showed the fastest decolorization in petri plates on different concentration, that is, 200 mg/L, 400 mg/L, and 600 mg/L. All these four species wer...
متن کاملLigninolytic enzyme activities alternate with mushroom produc- tion during industrial cultivation of Pleurotus ostreatus on wheat- straw-based substrate
Two commercial Pleurotus ostreatus strains (030 and K12) were cultivated under industrial conditions on wheat straw blocks 1718 kg in weight. Within 10 weeks of cultivation, three flushes of fruiting body production were obtained with total yields of 4.2 and 4.1 kg mushrooms/substrate block and a biological efficiency (BE = total yield of fresh mushrooms per dry weight of substrate) of about 95...
متن کاملThe use of spent brewery grains for Pleurotus ostreatus cultivation and enzyme production.
In the brewing industry, spent brewery grains (SBGs) are byproducts with a low economic value. The potential use of this leftover as a substrate ingredient for Pleurotus ostreatus fruiting body cultivation and enzyme production was evaluated. The best substrate mixture for P. ostreatus mycelium growth comprised 30% wheat bran (WB), 68% beech sawdust (BS) and 2% CaCO3. On the substrates containi...
