Just as the expert in photomicrography amuses himself with diatoms, or the zoologist with insects, shells, and birds of gorgeous plumage, the bibliophile takes pleasure in reading the newest book or monograph that is "highly important and thought-provoking" but that no one else can seem to find a copy of.

如果他是地质学家的话，他会完完全全沉醉在岩石的切片里，把这些岩石的切片放到偏极光显微镜下面，就可以看到各式各样的颜色，变化万千。如果他是细菌学家，那他就会很高兴地收集产生各种颜色的细菌，甚至产生磷光的菌。

Eijkman thought his germ theory was confirmed when he noticed the chickens in the hospital yard, which were fed on leftovers from the patients' plates, were also showing signs of the disease.

当Eijkma看到医院院子里面的吃病人剩下的东西的鸡也出现病症的时候，他觉得他的细菌理论得到证实。他尝试隔离细菌。

"The rate of tularemia or 'rabbit feer' infection has significantly declined since the 1940s. Howeer, the bacteria would be ery deadly as an aerosolized terrorist weapon -- inhaling as few as 10 bacteria could be potentially deadly," said Allen, who also is a staff researcher with the eterans Affairs Iowa City Health Care System.

"野兔病和'兔热病'的感染几率自从1940s以来明显的下降，但是，这种细菌可以成为一种具有强致死性的雾化器恐怖武器—只要吸入10个细菌就可能致死，"Allen说，他也是一位艾奥瓦城的退伍军人卫生保健系统的医学研究员。

So in our test aantagonistic germ was isolated from ginger soil and was studied. 108 strains of germs were isolated by tube dilution assay from the soil of gingerin Qingmu town,Bazhong city. Q6 strain was screened from these strains of germsthough the first screened and rescreened double with deck agar method andimproved aperture-strikeing method.

本实验从巴中市青木镇堆放腐烂姜并且又长出健康姜苗的根际土中分离出106株细菌，在涂布有姜瘟病原菌青枯劳尔氏菌的肉汤培养基上进行初筛，得到6株对青枯劳尔氏菌有较强拮抗作用的细菌，通过摇瓶发酵后利用发酵液，采用改良的琼脂孔扩散实验复筛，获得一株具有强拮抗作用的菌株，命名为Q6号。

Rep-PCR method was used to conduct cluster analysis to the 39 bacterial isolates. rep-PCR analysis revealed that the 39 bacterial isolates could be divided into 12 clusters at the 0.9 dissimilarity percentage level. The 39 bacterial isolates had their own specific band patterns, showing obvious genomic heterogenicity and rich genotypic polymorphism genetic diversity between each isolate.

采用rep-PCR技术对39个细菌分离株进行聚类分析，在rep-PCR图谱的相异百分数为0.9的水平上被聚类为12个类群，39个分离株各自具有独特的带型，说明各细菌分离株的基因组之间存在显著异质性，表现出丰富的基因型多态性。

With two methods, plate cultivation and the novel semi-solid in situ cultivation method, strains belong to Family Leptothrix were isolated. XRF showed that the amorphous iron and manganese were two major metal elements of the precipitation formed by one strain of Leptothrix spp..

研究发现，铁细菌2号培养基为合适的分离培养基；采用平板涂布法分离出的2株氧化铁和锰的细菌，经系统发育地位的分析确定为纤发菌属；对运动纤发菌的产物分析确定无定形铁和锰为其主要金属元素；形态观察确定霍氏纤发菌呈树枝状鞘结构，而运动纤发菌呈蛛网状鞘结构。

The myxobacteria have a life cycle that is dominated by social behavior. During vegetative growth, cells prey on other bacteria in large groups by gliding motility. When faced with starvation, cells form a macroscopic fruiting body containing thousands of resting myxospores.

粘细菌运动、发育相关基因的克隆及分析粘细菌以具有复杂的多细胞社会学行为著称，它们能够在营养丰富的条件下在固体表面上滑行运动；又能在饥饿的条件下聚集形成子实体结构以及抗逆性的粘孢子。

In wet state, the BC shows no X-ray diffraction and NMR of cellulose Ⅰ.

在干态下，细菌纤维素有较高的结晶指数和较高的纤维素Ⅰ；而湿态下的细菌纤维素没有显示出纤维素Ⅰ晶型的X射线衍射特征峰和核磁共振图谱，结晶指数和晶粒尺寸都相对较小。

The cellulose Iα and crystallinity index of the bacterial cellulose in dried state are very high compared with the other native cellulose such as cotton and Valonia.In wet state,the BC shows no X-ray diffraction and NMR of cellulos...

在干态下，细菌纤维素有较高的结晶指数和较高的纤维素Iα；而湿态下的细菌纤维素没有显示出纤维素I晶型的X射线衍射特征峰和核磁共振图谱，结晶指数和晶粒尺寸都相对较小。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
