| 1 | 磁性纳米颗粒固定化细菌纤维素酶的活性和稳定性(英文)显示文摘在氨水溶液中进行Fe^(+2)和Fe^(+3)离子共沉淀并水热处理后制得磁性纳米颗粒Fe_3O_4,通过戊二醛活化将纤维素酶固定于其上.采用基于响应面法的Box-Behnken法(BBD)优化了制备条件,如磁性纳米颗粒浓度、戊二醛浓度、酶浓度和交联时间.BBD分析结果表明,用实验数据可合理调节二次模型.利用生成的基于统计数据的等高线评价了响应面的变化,以理解纳米颗粒和酶活性之间的关系.运用扫描电镜、X射线衍射和红外光谱表征了纳米颗粒上酶的尺寸、结构、形貌和结合情况.采用诸如pH值、温度、重复使用性和存储能力分析了固定化纤维素酶的活性和稳定性.发现固定后的纤维素酶表现出更好的稳定性和活性. | Kandasamy Selvam Muthusamy Govarthanan Duraisamy Senbagam Seralathan Kamala-Kannan Balakrishnan Senthilkumar Thangasamy Selvankumar | 2016 | Chinese Journal of Catalysis2016，37，11： | 1 |

| 3 | Screening,phylogenetic analysis and antibiotic sensitivity pattern of Salmonella enterica serovar Typhi isolates from typhoid asymptomatic carriers显示文摘Objective:To isolate the Salmonella enterica serovar Typhi(S.typhi) from asymptomatic typhoid carriers in the local population.To assess the antibiotic sensitivity and resistant pattern of S.typhi isolates against viable antibiotics and phylogenetic analysis of S.typhi isolates on the basis of 16S rDNA gene.Methods:S.typhi was isolated and identified based on the cultural characteristics on BSA(Bismuth Sulphite Agar),MacConkey agar,agglutination test with specific antiserum and phylogenetic analysis.5.typhi isolates were tested for sensitivity and resistant pattern with a number of viable antibiotics by disc diffusion method.Result:A total of 15 bile samples were collected from the food handlers to screen the typhoid asymptomatic carriers.Positive result was yielded for 3 out of 15 samples.S.typhi isolates showed resistant to amphicillin(100%), tetracyclin(100%),rifampicin(66.5%),ofloxacin(33.5%),cloxacillin(33.5%) and susceptibility to gentamycin(100%),amikacin(100%),chloramphenicol(100%),streptomycin(100%),kanamycin (100%),cprofloxacin(100%),amoxycillin(66.5%) and ofloxacin(66.5%).Conclusions:This study demonstrates the outbreak of typhoid fever occurs through asymptomatic carrier.In addition,this study also reveals the occurrence of considerable drug resistant among the S.typhi isolates. | Balaji Chandrasekaran Senthilkumar Balakrishnan | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，10： | 0 |
