不同白腐真菌复配方式对产酶的影响 总被引:1,自引:0,他引:1
通过对1株和由多株白腐真菌复配共同参与下的复合菌产酶量和达到最高酶活所需时间进行比较,筛选出白腐真菌最佳产酶的复配方式.结果表明,青顶拟多孔菌和糙皮侧耳菌两株菌相互发生协同作用,促进漆酶的分泌,产酶量为50.45U·mL-1;青顶拟多孔菌、糙皮侧耳菌和偏肿拟栓菌这3株菌在分泌过程中促进作用大于抑制作用,产酶量最高为75.98U·mL-1;青顶拟多孔菌、糙皮侧耳菌和血红密孔菌三者相互之间出现拮抗作用,产酶量最低为2.91 U·mL-1;实验证明,在白腐真菌之间既存在拮抗作用,也存在协同作用,因此达到最高酶活所用时间也不同. 相似文献

Natural and synthetic estrogens from sewage treatment systems are suspected to influence the reproductive health of the animals in the rivers.In this article we investigated the enzymatic treatment of three estrogens (estrone,17β-estradiol,and 17α-ethynyletstradiol) by a fungal laccase which oxidize phenolic compounds with dissolved oxygen.The elimination of the estrogenic activities by enzymatic oxidation was demonstrated by medaka vitellogenin assay.In addition,we developed an enzymatic treatment system comprised of β-D-glucuronidase and the laccase for 17β-estradiol 3-(β-D-glucuronide) degradation.The two enzymes eliminated 17β-estradiol 3-(β-D-glucuronide) and the intermediate,17β-estradiol,efficiently. 相似文献
