The secretome of Pleurotus sapidus.
Due to their unique capability to attack lignified biopolymers, extracellular enzymes of white-rot fungi enjoy an increasing interest in various fields of white biotechnology. The edible fungus Pleurotus sapidus was selected as a model organism for the analysis of the secretome by means of 2-DE. For enzyme production, the fungus was grown in submerged cultures either on peanut shells or on glass wool as a carrier material. Identification of the secreted enzymes was performed by tryptic digestion, ESI-MS/MS ab initio sequencing, and homology searches against public databases. The spectrum of secreted enzymes comprised various types of hydrolases and lignolytic enzymes of the manganese peroxidase/versatile peroxidase family. While peptidases were secreted mainly by the cultures grown on peanut shells, versatile peroxidase type enzymes dominated in the cultures grown on glass wool.
