lactis产生的具有抑菌活性的多肽类化合物，早已进行商业化生产，因而较易获得，现已被许多国家和地区批准作为食品防腐剂用于食品生产中。

This study has discussed that Lactic acid bacteria are isolated from 752 samples of milk and other dairy products, collected from 500 household in pastoral areas in Inner mongolia, and its biological properties are analyzed and studied.765 strains of lactic acid bacteria, including 28 species of Lactobacellus,2 species strains of Bifidobacterium, 9 species strains of Enterococcus, 3 species strains of Lactococcus, 1 specie of Streptococcus, 6 species of Leuconostoc,1 specie of Pediococcus , are identified.

从代表内蒙古牧区不同地域特点和独特生态环境的9个盟市18个牧业旗500多户牧民家庭，以目的采样和层次分类随机采样相结合的方法，共采集鲜乳及乳制品样品752份，分离到947株乳酸菌，并用形态、染色、培养特性及生化反应等实验对其进行了鉴定，有765株实验菌株分别归于7个属50个种和亚种，其中归于乳杆菌属的有28个种和亚种；归于双歧杆菌属的有2个种；归于肠球菌属的有9个种；归于链球菌属的有1个种；归于乳球菌属的有3个种和亚种；归于明串珠菌属的有6个种和亚种；归于片球菌属的有1个种。

The combined bioreactor, which consists of a bacteria zone and a fungi zone, can overcome the shortcoming of the traditional bioreactor. Both hydrophilic and hydrophobic volatile organic compounds and mephitic compounds in the odor gas can be removed effectively by the synergistic reaction of the bacteria and fungi in the combined bioreactor.

It has generally accepted that the predominant bacteria used in wastewater treatment are mesophilic bacteria, which highly effective and active in normal temperature.

但是在我国北方地区，冬季污水温度一般为5～10℃，此时，污泥中的中温菌代谢活性降低甚至丧失活性，对污水中有机物的降解能力大大下降，造成污水处理效率低下，出水无法达标。

In this research, we consider that the predominant bacteria in low temperature wastewater treatment in winter were cold-adapted microorganisms, the number of which increased as the temperature dropped more and more, but rarely high up to the number of mesophilic bacteria in normal temperature due to its low growth rate and the restriction of ecological factors, so that the total number and activity level of microorganism in activated sludge decreased.

随着污水温度的降低，污泥中冷适应微生物的数量逐渐增加，但由于冷适应微生物的生长速率相对较低，且容易受到各种生态因子的抑制作用，其数量无法达到常温下中温微生物的水平，使得污泥中微生物的总体数量和活性降低。

Sulfate-Reducing Bacteria was the most important bacteria in microbiologically influenced corrosion,the corrosion cause by SRB was about 10 percent of total corrosion.

硫酸盐还原菌是微生物腐蚀中最为重要的菌种，其引起的腐蚀约占所有腐蚀总量的10%。

The pathogenic bacterium of prepartum and intrapartum infectious pneumonia mostly were G- bacilli,the pathogenic bacterium of postpartum infectious pneumonia mostly were G- bacilli and staphylococcus aureus.6.The drug resistant rates of G- bacteria to penicillins,cephalosporins,and monocyclicβ-lactam antibiotic were high,However,their compound of addingβ-lactamase inhibitor agents was relatively low resistance,and all G- bacteria were sensitive to carbapenem antibiotics.

产前及产时感染性肺炎的病原菌以G-杆菌多见，而产后感染性肺炎的病原菌主要为G-杆菌和金葡菌。6.G-菌对青霉素类、头孢菌素类及单环类的β内酰胺类抗生素耐药率高，但对其添加β内酰胺酶抑制剂的复合制剂耐药率较低，对碳青霉烯类抗生素均敏感；金葡菌对苯唑西林耐药率低，对万古霉素均敏感。7。

"You just put the peptide drug together with the bacteria and it sticks to the bacteria," Sean Nair, who worked on the study, said in a telephone interview.

&你刚才放多肽药物与细菌在一起并且粘它到细菌上，&从事研究的Sean Nair在电话采访中说。

The growth of pathogenic bacteria during storage and their D10 values by irradiation in short necked clam were evaluated. The results showed that the D10 values of the total bacteria count, E.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
