Abstract

Coriolopsis gallica and Phanerochaete chrysosporium were selected for their potential ability to degrade five dyes in an artificial effluent. Degradation experiments were carried out in N-rich (C:N ratio 11.6:1) and N-limited (116:1) conditions at an effluent concentration of 100 mg l(-1). P. chrysosporium decolourised 53.6% of the effluent in N-rich conditions and 48% in N-limited conditions. C. gallica decolourised 80.7% in N-rich conditions and 86.9% in N-limited conditions. Nitrogen supplementation improved enzyme activities and dye decolourisation for P. chrysosporium. Additional nitrogen increased enzyme activities for C. gallica but did not improve decolourisation. The results highlight the potential of C. gallica for textile dye degradation.

摘要

选用毛栓菌和黄孢原毛平革菌，研究它们对人工废水中五种染料的降解能力。在废水浓度为100 mg l(-1)的富氮（碳氮比11.6:1）和氮限制（116:1）条件下进行降解实验。在富氮条件下，黄孢原毛平革菌使废水脱色53.6%，在氮限制条件下为48%。在富氮条件下，毛栓菌使废水脱色80.7%，在氮限制条件下为86.9%。补充氮提高了黄孢原毛平革菌的酶活性和染料脱色率。额外的氮增加了毛栓菌的酶活性，但没有提高脱色率。结果突出了毛栓菌在纺织染料降解方面的潜力。
