Fusarium wilt is a common fungal disease in sesame caused by Fusarium oxysporum ***(FOS).To determine the toxin production profiles of the FOS isolates with different pathogenicity levels under various culture conditions,we assessed the content variation of fusaric acid(FA)and 9,10-dehydrofusaric acid(9,10-DFA)produced by the four representative FOS *** indicated that the concentration of FA reached to a maximum of 2848.66μg/mL in Czapek medium,while 9,10-DFA was mainly produced in Richard and Lowcarbon Richard *** concentration of 9,10-DFA on Richard culture medium varied from 0μg/mL to 716.89μg/*** the five culture media used in this study,Czapek culture medium was the most conductive to produce *** production was significantly affected by culture medium,culture time,and their *** suggest that there is no correlation between toxin production and pathogenicity level of FOS *** findings provide key information for the mechanism analysis of FOS-sesame interaction and pathogen control.

The problems of robust H-infinity fault tolerant control with time-delays are studied for a class of nonlinear networked control systems. The T-S fuzzy model is employed to describe nonlinear plant. By established actuator fault model, the state feedback controller is designed. A sufficient condition for the asymptotic stability of closed-loop system is given based on Lyapunov stability theory and linear matrix inequality method, which can guarantee robust stability of network control system with actuator faults and disturbances.

由尖孢镰刀菌芝麻专化型(Fusarium oxysporum ***,FOS)侵染引起的芝麻枯萎病是芝麻生产上的重要真菌病害。为筛选出能够应用于芝麻枯萎病生物防治的拮抗微生物,利用采自我国不同省份(区)的芝麻、荩草和紫花地丁根际土壤样品进行微生物的分离、纯化及尖孢镰刀菌拮抗作用测定,并通过室内盆栽试验验证重要拮抗菌对芝麻苗期枯萎病的防控效果;进一步结合形态学观察、生理生化特性测定以及16S rDNA序列分析,开展了拮抗菌的分类鉴定。结果表明,在来源于我国6个省份(区)的33份土壤样品中,共分离获得细菌1077株、真菌515株、放线菌554株,筛选出对尖孢镰刀菌具有拮抗作用的细菌17株、真菌10株、放线菌51株。其中,细菌菌株SF3-33和SF4-11的拮抗作用最为显著,对尖孢镰刀菌的最大抑菌带均为1.0 cm;且其对由强致病性FOS菌株引起的芝麻苗期枯萎病的最大防效分别达到83.74%和63.13%。SF3-33和SF4-11菌株分别被鉴定为地衣芽孢杆菌(Bacillus licheniformis)和皮奥显亚类芽孢杆菌(Paenibacillus peoriae)。综上,筛选出了大量拮抗尖孢镰刀菌菌丝生长的根际微生物,其中细菌菌株SF3-33和SF4-11能够显著减弱芝麻苗期枯萎病的发生,为进一步探索芝麻枯萎病生物防治技术提供了具有较好应用潜力的研究材料。

载药微针可以实现一次性快速药物递送,无需二次药物涂敷与输送过程,但其不佳的载药量与刺入率造成了给药效率差的问题。研发了一种基于数字光处理(DLP)3D打印技术的高给药效率微针(HDMN)制备工艺。通过在载药微针上构建锯齿状针体结构与阶梯状载药结构来提高载药微针的刺入率与载药量,进而提高给药效率。实验结果表明使用环氧丙烯酸酯(EA)打印微针时,当曝光时间为700 ms、打印层厚为30μm时,打印出的微针实际尺寸与理论尺寸平均误差最小为9.2%。利用旋涂法在微针表面交联聚乙二醇二丙烯酸酯(PEGDA)以改善微针生物相容性。显微镜观察发现,当交联层数为1层时,PEGDA均匀地覆盖在微针表面。石蜡膜穿刺实验结果表明,HDMN穿透了2层石蜡膜,而相同实验条件下的传统载药微针仅穿透了1层。药物释放实验结果表明,HDMN相对于传统载药微针在猪皮内留下的模拟药物浓度提升了61%。该研究为后续通过改善微针结构来优化微针性能研究提供了有益借鉴。
