棒曲霉毒素在出口浓缩苹果汁中普遍存在，特别是在榨季的中后期原料苹果的腐烂率较高时其质量分数超标的风险很大，在HACCP食品安全管理体系审核实践中，发现浓缩苹果汁生产过程中，控制棒曲霉毒素的方法和途径有多种，但不论哪一种或多种组合应用都应关注原料果的品种、生产季节和储存温度，因为这些因素是降低棒曲霉毒素质量分数和生产成本的关键因素。

After the cells were treated by high concentration toxin for 4d, the content of nitrate-nitrogen in cells were lower markedly than the contrast, after the cells were treated by middle and low concentration toxin for 7d, the content of nitrate-nitrogen in cells were lowered. 3 groups of toxin treating all lowered the total phosphorus content. At the end of test, the phosphorus contently of low, middle, high concentration treating groups were 74.98%, 76.47% and 84.00% of the contrast respectively. The ACP activity of 3 treating groups compared with the contrast appeared the tendency of first lowering then raising.

高浓度毒素处理细胞4d后，细胞内硝态氮含量显著低于对照；中、低浓度毒素处理细胞7d后降低了胞内硝态氮含量。3组毒素处理均降低了胞内总磷含量，到实验结束时，低、中、高浓度处理组的胞内磷含量分别为对照的74.98%、76.47%和84.00%。3组处理组ACP活力与对照相比呈现先降低后升高的趋势。

Under the selection pressure of crude toxin filtration, three kinds of treatment methods and four kinds of phytotoxin concentrations were used to screen the blast-resistant callus phenylalanine, The result indicated that the crude toxin filtration inhibited evidently the callus induction, subculture and differentiation, with the increasing of the toxin concentration, the inhibiting getting enhanced.

以稻瘟病病原菌粗毒素提取液为选择压，对水稻进行抗病性筛选，结果表明：粗毒素提取液对水稻愈伤组织诱导、继代及分化有明显的抑制作用，抑制程度随毒素浓度提高而增强，且品种间差异显著。

To obtain the tervalent fusion toxin gene, three toxin gene fragments from three species of Vibrio parahaemolyticus, Vibrio vulnificus and Vibrio mimicus were connected with the flexible linker using overlap extension PCR. The three toxin gene fragments respectively encode the mature proteins of the thermostable direct hemolysin of V. parahaemolyticus, the cytotoxin of V. vulnificus and the heat-labile hemolysin of V.

采用柔性Linker和重叠延伸PCR方法将三个毒素基因，即副溶血性弧菌的耐热型直接溶血素基因tdh、创伤弧菌的溶细胞毒素基因vvhA和拟态弧菌的热不稳定型溶血素基因vmhA的成熟蛋白基因片段进行串联，得到三联融合毒素基因tdh-vvhA-vmhA。

In this experiment, a new method was used to purify the toxin protein produced by Verticillium dahliae. The supernatant of fungus culture was frozen and dried with Lyophilizer first, and then dialysed by Dialysis Membranes (MWCO 1000) after dissolved in distilled water. This method can eliminate the salt and sucrose in culture medium and reserve the protein component almost completely. VD-toxin were analysed using sodium dodecyl sulfate polyacrylamide gel analysis. The results indicated that the protein components were very complex, and included glycoprotein within 35.8kDa-83.2kDa. Furthermore, treatments on glycoproteins with high temperature, conA and proteinase alleviated, not abolished, their activities.NO and H_2O_2 production were assayed in two cultivars of cotton cells which were treated with VD-toxin.
