摘要
从自然界中采集 ,经分离、纯化获得在愈创木酚培养基平板上产生变色圈 ,且菌落直径与变色圈直径的比值小于 1的 12株真菌。将 12株真菌接种到桉木粉无机盐培养基中 30℃培养 15d,测定其选择性指数 (SF) ,获得两株木素降解能力较高的菌株 F1、F7,SF值分别为 3.0 8和 2 .70。将12株菌株接种于含 2、4—二氯酚的漂白废水中 39℃培养 7d,获得两株高效降解 2、4—氯酚的菌株 F7、F9,其降解率分别为 87.58%和 89.6 5%。
WT5”BZ]12 fungi which showed color zone in the guaiacols medium were obtained from the nature by isolation and purification for several times.The ratio of the diameter of mycelium and that of colored zone was less than one.12 fungi were inoculated in the medium which contained eucalyptu wood powder and miners,and incubated at 39 ℃ for 15 days.The Selection Factors were determined.Two strains (F1,F7) had high capacity for deligification and SF values were 3.08 and 2.70 respectively.The bio degradation of 2、4—dichlorophenol by these fungi was studied.12 fungi were inoculated in the bleach effluent medium which was added with 2、4—dichlorophenol,and incubated at 39 ℃ for 7 days.Two strains (F7,F9) had high capacity for bio degradation of 2、4—dichlorophenol.The rates of degradation were 87.58 % and 89.65 % respectively.
