研究了白腐真菌木黄孢、栓菌、黄孢原毛平革菌和陆地石霉矿化3,4-二氯苯胺、狄氏剂和菲的能力。 hirsutum 没有矿化任何测试化合物，但其他菌株不同程度地部分矿化它们。单位生物量的相对降解率为T。杂色>C.木质>P。金孢子虫。获得了水溶性代谢中间体产生的证据，但没有尝试表征这些中间体。结果发现，添加微量矿物质营养素、维生素和1.5 mm3,4-二甲氧基苯甲醇（藜芦醇）的矿物盐-葡萄糖培养基的矿化率最高。在这些实验中，从未检测到细胞外木质素酶（木质素过氧化物酶）活性。
The abilities of the white-rot fungiChrysosporium lignorum, Trametes versicolor, Phanerochaete chrysosporiumandStereum hirsutumto mineralize 3,4-dichloroaniline, dieldrin and phenanthrene were investigated.S. hirsutumdid not mineralize any of the test compounds but the other strains partly mineralized them all to varying degrees. The relative degradation rates per unit biomass wereT. versicolor>C. lignorum>P. chrysosporium. Evidence was obtained for the production of water-soluble metabolic intermediates but no attempt was made to characterize these. It was found that mineral salts-glucose medium supplemented with trace mineral nutrients, vitamins and 1.5 mm3,4-dimethoxybenzyl alcohol (veratryl alcohol) resulted in the highest mineralization rate. At no time in these experiments was there detectable extracellular ligninase (lignin peroxidase) activity.
