Based on long-term data from operation of a new-style oxidation ditch process at Zhuji Feida-hongyu wastewater treatment plant in Zhejiang Province, we propose a new principle for the interaction of Tubificidae and microorganisms and obtained a mathematical description of pollutant input and output over time in this system. Then a transmission function for interaction system of Tubificidae was constructed to simultaneously simulate the pollutant removal by Tubificidae during wastewater treatment and sludge degradation.

PCR-DGGE technology is a very important analytical tool with the development of molecular biology. Comparing with the traditional identification methods, PCR-DGGE technique is fast and easy to operate. The technology can also achieve the effect of separation for Unculturable microorganisms. Thus, the technology is widespread concern and attention in microbial ecology.

PCR-DGGE技术是随着现代分子生物学发展起来的一种很重要的分析手段，与传统的种群鉴定方法相比，PCR-DGGE技术具有快速和操作简便等优点，对于不可培养的微生物也能达到分离的效果，因而在微生物生态学中受到普遍关注与重视。

METHODS: The suspected pathogens and unculturable phylotypes in subgingival oral flora from chronic periodontitis sufferer were detected by PCR based on species-specific ribosomal 16S rRNA gene. A KAPPA calculation was used to analyze the relationship between any two bacterial species.

使用基于16S rRNA基因检测的PCR法，对慢性牙周炎患者龈下菌斑中牙周可疑致病微生物和代表性未获培养微生物进行检测，通过KAPPA检验分析任意两种细菌对间的关系。

Objective:The koji, production process and product index of North of Hunan unhusked rice wine and Middle Hunan rice wine were studied to give evidence for industrial production of unhusked rice wine; Methods: Glucoamylase activity, alcoholic fermentation activity, alcoholicity, all ester and the number of microbe were examined with ordinary ways; Results:The number of microbe and Rhiz.

目的：对湘北谷酒与湘中米酒酒曲、生产工艺以及成品酒指标进行比较，为谷酒的产业化生产提供依据；方法：采用常规方法测定、比较糖化力、酒化力、酒精度、总酯、微生物含量；结果：谷酒酒曲的微生物总数、根霉菌数糖化力与湘中米酒酒曲基本相同，但酵母数、酒化力略高于米酒酒曲；湘北谷酒的酒度、出酒率和总酯均高于湘中米酒，高级醇含量基本持平，感官指标优于湘中米酒；结论：谷酒较米酒的发酵工艺更合理，蒸馏方式更科学，产品质量更稳定；谷酒比米酒更适合大规模产业化。

The results showed that pH of the irradiated sediment core is higher than the unsterilized one,and microorganisms could have an effect on the pH of sediments.All the four sediments are in the strong reductive environment at the depth of 7～30 cm,and the values of Eh are quite closer,the main factor that affect the redox environment may be the compaction of the sediment.All the sediments had a cumulation of phosphorus at the surface layer,and the total phosphorus of the sediments at the depth of 4～10 cm are lower than the average.It is indicated that phosphorus had been redistributed at the suface layer.

本研究采集太湖梅梁湾沉积物，通过印Co.y射线辐照、添加可溶性淀粉等处理研究微生物活性对太湖沉积物pH，Eh及总磷分布影响，以揭示微生物在湖泊沉积物中的沉积后作用，为探索富营养化湖泊表层沉积物磷的归趋提供理论基础。1 材料与方法1.1 样品采集和处理2005年1 1月，采用自制的柱状采泥器采集太湖梅梁湾沉积物，采样位点为31.30.306 N.120.13.370 E，采集后立即带回实验室，其理化性质见表1。

Institute of Microbiology and Epidemicology, Academy of Military medical Science, Beijing,100071,China The performance of BL3 safety laboratory in preventing experimental aerosol diffusion and sterilizing microbe aerosols through high efficiency filter in a ventilation system was tasted.Aerosols of uranin, vibrio phage and Bacillus subtilis var. niger spores were used for the test.

P3级微生物安全实验室防气溶胶扩散性能的检测胡庆轩车凤翔摘要：采用荧光素钠、弧菌噬菌体和枯草芽胞杆菌气溶胶对P3级微生物安全实验室防气溶胶扩散性能及其排风系统中高效过滤器滤除气溶胶的效果进行了检测。

Growing sweet corn in summer could absorb redundant nutritional ingredients largely in the soil, but the number of fungi was high and the ratio of B/F is not obvious compared with CK. On the contrary, planting leafy vegetables had no obvious effect on the composing of soil microbe and the decruce of the number of pathogen of cucumber, although it could reduce the content of salty in the soil. The crop green manure of villose vetch could reduce the content of salty in the degree, but the sum of microbe in the soil reduced a little.

夏季休闲期间种植甜玉米可大量吸收土壤中多余的营养成分，但真菌数量偏高，B/F值与对照相比相差不大；种植速生叶菜虽然能降低土壤盐分含量，但对降低黄瓜致病菌数量和改善微生物区系组成方面无显著效果；豆科作物毛苕子在一定程度上降低了土壤盐分含量，但土壤微生物总量有所减少。
