| 中文摘要 |
| 研究了黄孢原毛平革菌对聚丙烯酰胺(PAM)的生物降解,从葡萄糖的加入量、pH、N浓度、Mn2+浓度和降解时间5个方面考察了对PAM降解的影响.结果表明,黄孢原毛平革菌对聚丙烯酰胺具有特殊的酶催化降解的能力,降解率可达50%,限氮条件(NH4+=0.2g/L)和Mn2+浓度(Mn2+=0.017 5g/L)是菌株产聚丙烯酰胺降解酶的最佳条件. |
| 英文摘要 |
| Phanerochaete chrysosporium was introduced into biodegradation of polyacrylamide(PAM),and effects of glucose amount,pH,N concentration,Mn2+ concentration and biodegradation time on biodegradation of PAM were studied.Results show that Phanerochaete chrysosporium has special abilities of enzyme catalysis biodegradation of PAM.And the removal rate of PAM is 50%.Nitrogen limitation(NH4+=0.2g/L) and Mn2+ concentration(Mn2+=(0.0175)g/L) are optima of producing PAM biodegradation enzyme. |
