在相对湿度为97-99%的条件下，研究了白杨上的3种腐朽菌和石膏板上的2种软腐菌培养物的挥发性气体释放。培养箱中的空气样品分别用Tenax TA管和2，4-二硝基苯肼吸附柱吸附，用热脱附-气相色谱法和高效液相色谱法进行分析。挥发性代谢产物的组成在所研究的真菌物种之间差异显着。褐腐真菌的排放物包括蒎烯，丙烯醛和一些酮。另一方面，在生长的6-10周期间，来自白杨上的褐腐真菌培养物的醇的生产是差的。软腐菌主要释放酮类和醇类物质。还观察到真菌生长减少醛排放的显著能力。
Volatile emissions from the cultures of three decay fungi on aspen and two soft rot fungi on gypsum board were investigated at 97–99% relative humidity of air. Air samples from the incubation chambers were adsorbed on Tenax TA tubes and 2,4-dinitrophenylhydrazine cartridges, and analyzed by thermal desorption-gas chromatography and HPLC, respectively. The composition of volatile metabolites varied significantly between the fungal species studied. Emissions of the brown rot fungi included pinenes, acrolein and few ketones. On the other hand, the production of alcohols from brown rot fungal cultures on aspen was poor during the 6–10 weeks of growth. The soft rot fungi emitted mostly ketones and alcohols. A significant ability of fungal growth to decrease aldehyde emissions was also observed.
