本研究以一株新分离的里氏木霉F21为研究对象，研究了其对极性[茜素红S(ARS)]和非极性[奎尼沙林绿SS(QGSS)]的生物还原作用。在培养7d内，李氏木霉F21对ARS和QGSS的生物修复效果分别为77.78%和98.31%。在pH为4、温度为27℃的条件下，葡萄糖和酵母膏的生物吸附率最高(ARS=33.7%，QGSS=74.7%)，酶生物降解率最高(ARS=44.1%，QGSS=23.6%)。李氏木霉F21产生的漆酶和邻苯二酚1，2-双加氧酶参与了ARS和QGSS向酚类和羧酸类化合物的分子转化，而不产生有毒的芳香胺。这项研究表明，利氏木霉F21可能是一个很好的候选生物修复的工业废水污染的蒽醌染料。
In this study, a newly isolated ascomycete fungus Trichoderma lixii F21 was explored to bioremediate the polar [Alizarin Red S (ARS)] and non-polar [Quinizarine Green SS (QGSS)] anthraquinone dyes. The bioremediation of ARS and QGSS by T. lixii F21 was found to be 77.78 and 98.31 %, respectively, via biosorption and enzymatic processes within 7 days of incubation. The maximum biosorption (ARS = 33.7 % and QGSS = 74.7 %) and enzymatic biodegradation (ARS = 44.1 % and QGSS = 23.6 %) were observed at pH 4 and 27 A degrees C in the presence of glucose and yeast extract. The laccase and catechol 1,2-dioxygenase produced by T. lixii F21 were involved in the molecular conversions of ARS and QGSS to phenolic and carboxylic acid compounds, without the formation of toxic aromatic amines. This study suggests that T. lixii F21 may be a good candidate for the bioremediation of industrial effluents contaminated with anthraquinone dyes.
