Abstract: 谢瓦氏曲霉间型变种Aspergillus chevalieri var. intermedius俗称“金花菌”,是茯砖茶发酵中的优势菌种,该菌在不同的渗透压胁迫下产生不同类型的孢子。采用抑制性差减杂交技术(suppression subtractive hybridization,SSH),以低渗条件下产生的子囊孢子和高渗条件下产生的分生孢子为材料分别与营养菌丝体构建两个正反向文库。每个库随机挑选400个阳性克隆进行测序。然后将所得到的基因片段在GenBank进行BLASTx和BLASTn同源比对,筛选出的差异表达的基因涉及蛋白质代谢、细胞代谢、转录调控等多个方面,其中可能参与有性产孢调控的基因有13条,可能参与无性产孢调控的基因有10条。

Abstract: Two isolates of Paecilomyces gunnii, anamorph of Cordyceps gunnii, with and without producing analgesic activity, were tested by using proteomic analysis in order to find the correlation between protein differential expression and analgesic activity. The results showed that expression of 51 protein spots significantly increased in the active isolate HZJ-1. Among the spots, structures of 39 proteins with various functions were identified. Most of the proteins were related to metabolism, and the NADP-specific glutamate dehydrogenase might mediate long-term depression of synaptic transmission and reduce pain. The functions of several conserved hypothetical proteins have not been reported, and are needed for further studies.

Abstract: The symbiotic seed germination of Pleione bulbocodioides (Franch.) Rolfe, a traditional Chinese medicine, was investigated. The results showed that the mycorrhizal fungi isolated from pleione bulbocodioides, GN21, GN23 and GN24 promoted the seed germination evidently, and the germination rate of GN21 was up to 84.6%, much better than the others and control. However, the fungal species isolated from the same species of orchid, even if belonging to the same genus, could not be always to stimulate the seed germination, some species even became pathogens under the circumstances of poor nutrition.

Abstract: High-yielding strain TM 11 of Mortierella alpina producing gamma-linolenic acid was selected by use of UV and LiCl. The yield of ?-linolenic acid was about 3 times that of its start strain SM96. In this research, some work about selecting optimum fermentation conditions was done. With orthogonal design, the optimum medium formula for the production of ?-linolenic acid was obtained, which contained MgSO47H2O1.0g, VB6 150mg/L, yeast extract 6g/L, glucose100g/L, nutritional salt solution1mL/L, K2HPO42g/L.The TM11 had a biomass of18.0213 g/L and 10.8128 g/L oil and 668mg/LGLA in this medium.

Abstract: A bottom-up PM emission model was developed based on the production technologies and PM emission control devices in Chinese cement industry. Through analyzing the historical distribution of technologies in cement producing and the impact of standards on PM emission control from cement industry, emission factors of cement industry in China during 1990-2004 were generated by this technology-based model, and emission inventories were developed thereby. Emission factor decreased from 27.9 kg x t(-1) cement in 1990 to 8.05 kg x t(-1) cement in 2004. Emissions of PM from cement industry in China reached the peak value in 1997, with 1044 x 10(4) t of TSP, 716 x 10(4) t of PM10, 436 x 10(4) t of PM2.5 emitted, then decreased until 2001, and increased slowly again during 2001-2004. The distribution of PM emissions among provinces is uneven. Shandong, Guangdong, Hebei, Jiangsu, Zhejiang, and Henan contribute more than 50% of emissions of China. Rapid spread of pre-calcining kilns in China and implementation of Emission Standard of Air Pollutants for Cement Industry in 2004 will probably decrease PM emissions from cement industry to a large extent, leading to obvious variation on PM pollution characteristics in China.

Abstract: 研究了电极材料(Pt/Ti)对铁电PLZT(7.5/65/35)陶瓷薄膜结构和性能的影响.认为在Pt层厚度一定时,Ti层的厚度对铁电薄膜的结构和性能有显著影响.当Ti层过厚或过薄时,铁电薄膜的结构较差;而当Ti层的厚度适中时,则铁电薄膜的显向下微结构均匀,电性能较好,典型的剩余极化强度和矫顽场分别为27.8μC·cm-2和65.1kV·cm-1.

Abstract: 应用来源于美国、阿根廷的我国对外检疫性有害生物大豆猝死综合症病菌枝状镰孢Fusarium virguliforme共8个菌株,分别在43℃至47℃ 5个温度梯度下水浴处理1min至5min 5个时间梯度,荧光染色后,经单细胞微量分析系统进行活性检测分析,设置传统萌发试验作为对照,结果表明:该病菌在47℃水浴处理4min即全部失活,SPSS统计分析得出该病菌的活性检测值与处理温度呈极显著负相关,而与处理时间(除菌株2-1和22825呈显著负相关外)均呈极显著负相关;所设置的孢子萌发率与处理温度和处理时间之间也呈极显著负相关;活性检测值与萌发率两者之间具有极显著的正相关性.本研究表明活性检测可以替代传统的孢子萌发方法,从而大幅度缩短该病菌活性检测时间,明显提高检测效率.
