This study was conducted to compare the VOCs of white-rot fungi, Ganoderma lingzhi, Irpex lacteus, and Phlebiopsis pilatii, according to dextrin concentration. Each strain was cultured under PDB (Con), PDB + Dextrin 1% (Dex1), PDB + Dextrin 5% (Dex5), and PDB + Dextrin 10% (Dex10) conditions, and VOCs were analyzed by HS-SPME GC-MS in comparison with uninoculated media, including PDB, PDB + Dextrin 1% (BDex1), PDB + Dextrin 5% (BDex5), and PDB + Dextrin 10% (BDex10). As a result of GC-MS analysis, a total of 9 VOCs were detected in the uninoculated media, which belonged to alcohols, aldehydes, esters, phenolic compounds, and hydrocarbons. In G. lingzhi, a total of 14 VOCs were detected, belonging to alcohols, aldehydes, esters, terpenes, and phenolic compounds. In I. lacteus, a total of 9 VOCs were detected, belonging to alcohols, esters, ketones, nitrogen-containing compounds, and furans. In P. pilatii, a total of 7 VOCs were detected, belonging to alcohols, esters, nitrogen-containing compounds, terpenes, phenolic compounds, and carboxylic acids. Among them, alcohols and terpenes in G. lingzhi, nitrogen-containing compounds and furans in I. lacteus, and nitrogen-containing compounds and carboxylic acids in P. pilatii were newly detected compared to the uninoculated media. These results indicate that different VOC production patterns were observed among strains even under the same carbon source conditions, confirming differences in metabolic characteristics among white-rot fungi. These findings are expected to serve as fundamental data for the production of functional metabolites and the design of bioprocesses based on the understanding of strain-specific metabolic characteristics.
