研究了白腐菌Phlebia brevispora TMIC33929单独培养和与其生长促进菌Enterbacter sp.共培养时的染料脱色能力。在不同pH值的低氮液体培养条件下，对TN3W-14菌株进行了评价。在pH值为4.5和7.0时，无菌真菌对刚果红和结晶紫的去除效果相似。在pH值为9.0时，细菌对结晶紫的脱色效果仅略好于真菌。与无菌真菌相比，共培养对混合染料中结晶紫的去除效果不明显，但对混合染料中结晶紫的去除效果较好，在pH值为9.0时混合染料脱色效果最好。与细菌在染料上的生长不同，染料在所有pH下都不抑制真菌菌丝的生长，但共培养的菌丝生长相对较高。
The dye decolorization potential of the white-rot fungus Phlebia brevispora TMIC33929 when grown alone or in coculture with its growth-promoting bacterium Enterobacter sp. TN3W-14 was evaluated in low nitrogen liquid medium at different pHs. Axenic fungus removed a similar amount of Congo red and crystal violet at pH 4.5 and 7.0, respectively. The bacterium alone achieved only slightly better decolorization of crystal violet than the fungus at pH 9.0. Compared with axenic fungus, cocultures provided no increased crystal violet removal but achieved higher removal of crystal violet in mixed dye at all pHs, and the best-mixed dye decolorization at pH 9.0. Unlike bacterial growth on dyes, growth of fungal mycelia was not inhibited by the dyes at all pH but the cocultures gave comparably higher mycelial growth.
