Since enzyme secretion is strongly modulated by environmental factors, evaluation of growth conditions is of utmost importance to achieve optimal enzyme production. In this work, a nonsequenced wood-rotting fungus, Lentinus crinitus, was used for secretome analysis by enzymatic assays and a proteomics approach. Enzyme production was assessed after the fungus was cultured in seven different carbon sources and three nitrogen-containing compounds. The biomass yields and secreted protein arrays differed drastically among growing conditions. A mixture of secreted extracts derived from solid and liquid cultures was inspected by shotgun mass spectrometry and two-dimensional gel electrophoresis (2-DE) prior to analysis via LC–MS/MS. Proteins were identified using mass spectrometry (MS)-driven BLAST. The spectrum of secreted proteins comprised CAZymes, oxidase/reductases, proteases, and lipase/esterases. Although preseparation by 2-DE improved the number of identifications (162) compared with the shotgun approach (98 identifications), the two strategies revealed similar protein patterns. Culture media with reduced water content stimulated the expression of oxidases/reductases, while hydrolases were induced during submerged fermentation. The diversity of proteins observed within both the CAZyme and oxidoreductase groups revealed in this fungus a powerful arsenal of enzymes dedicated to the breakdown and consumption of lignocellulose. %I ACS Publications
