| 1 | Optimization of phenol degradation by Candida tropicalis Z-04 using Plackett-Burman design and response surface methodology显示文摘Statistical experimental designs were used to optimize the process of phenol degradation by Candida tropicalis Z-04,isolated from phenol-degrading aerobic granules.The most important factors influencing phenol degradation (p<0.05),as identified by a two-level Plackett-Burman design with 11 variables,were yeast extract,phenol,inoculum size,and temperature.Steepest ascent method was undertaken to determine the optimal regions of these four significant factors.Central composite design (CCD) and response surface analysis were adopted to further investigate the mutual interactions between these variables and to identify their optimal values that would generate maximum phenol degradation.The analysis results indicated that interactions between yeast extract and temperature,phenol and temperature,inoculum size and temperature affected the response variable (phenol degradation) significantly.The predicted results showed that the maximum removal efficiency of phenol (99.10%) could be obtained under the optimum conditions of yeast extract 0.41 g/L,phenol 1.03 g/L,inoculum size 1.43% (V/V) and temperature 30.04°C.These predicted values were further verified by validation experiments.The excellent correlation between predicted and experimental values confirmed the validity and practicability of this statistical optimum strategy.This study indicated the excellent ability of C.tropicalis Z-04 in degrading high-strength phenol.Optimal conditions obtained in this experiment laid a solid foundation for further use of this microorganism in the treatment of highstrength phenol effluents. | Jiangya Zhou Xiaojuan Yu Cong Ding Zhiping Wang Qianqian Zhou Hao Pao Weimin Ca | 2011 | Journal of Environmental Sciences2011，23，1： | 48 |

| 7 | Expression profile of CYP402C1 and its role in resistance to imidacloprid in the whitefly, Bemisia tabaci显示文摘Bemisia tabaci(Gennadius)(Hemiptera:Aleyrodidae)is a cosmopolitan insect pest causing serious damage to crop production.Cytochromes P450(CYPs)of B.tabaci are widely known to be involved in the metabolic resistance to a variety of insecticides,continuously increasing the difficulty in controlling this pest.In this study,four P450 genes(CYP6CMI,CYP6CXl,CYP6CX3,and CYP402CI)in B.tabaci exhibited correlations with the resistance to imidacloprid.We have focused on trying to understand the function and metabolism capacity of CYP402C1.The expression profiles of CYP402C1 were examined by reverse transcription quantitative real-time PCR and fluorescence in situ hybridizations.Its role in resistance to imidacloprid was investigated by RNA interference,transgenic Drosophila melanogaster,and heterologous expression.The results showed that CYP402CI was highly expressed in the active feeding stages of B.tabaci,such as nymphs and female adults.CYP402C1 was mainly expressed in midguts of nymphs and adults,especially in the filter chamber.Knockdown of CYP402CI significantly decreased the resistance of B.tabaci to imidacloprid by 3.96-fold(50%lethal concentration:186.46 versus 47.08 mg/L).Overexpression of CYP402CI in a transgenic D.melanogaster line(Gal4>UAS-CYP402CI)significantly increased the resistance to imidacloprid from 12.68-to 14.92-fold(129.01 and 151.80 mg/L versus 1925.14 mg/L).The heterologous expression of CYP402CI showed a metabolism ability of imidacloprid(imidacloprid decreased by 12.51%within 2 h).This study provides new insights for CYP402C1 function in B.tabaci and will help develop new strategies in B.tabaci control and its insecticide resistance. | Lei Guo Zhuang Zhang Wei Xu Jiangya Ma Ni Liang Changyou Li Dong Chu | 2023 | Insect Science2023，30，1： | 0 |
