Influence of Trace Elements on Ligninolytic Enzyme Activity of Pleurotus ostreatus and P. pulmonarius
Trace elements, at tolerable concentrations, are either part of the active site or act as an activity modulator of ligninolytic enzymes of white-rot mushrooms. They are usually in plant raw materials in a non-toxic amount or non-available and extractable forms. This study evaluated the effects of Fe, Zn, and Se on the activity of laccase and Mn-oxidizing peroxidases of P. ostreatus and P. pulmo...
متن کاملInfluence 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 کاملMechanism of peroxidase inactivation in liquid cultures of the ligninolytic fungus pleurotus pulmonarius
It has recently been reported that Pleurotus pulmonarius secretes a versatile peroxidase that oxidizes Mn2+, as well as different phenolic and nonphenolic aromatic compounds; this enzyme has also been detected in other Pleurotus species and in Bjerkandera species. During culture production of the enzyme, the activity of the main peak was as high as 1,000 U/liter (measured on the basis of the Mn...
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 کاملIn vitro antileishmanial activity and apoptosis induction of Pleurotus ostreatus alcoholic extract on Leishmania major
Background and objectives: Leishmaniasis is caused by the genus Leishmania. Medications such as antimony compounds for the treatment of the disease are associated with limitations along with several side effects and disease recurrence; thus, evaluation of natural compounds with history of antimicrobial properties such as Pleurotus ostreatus, is of a great im...
