    质粒的方法就溶液123的方法就可以了 DNA可以参考提取动物、植物DNA的方法 更快速的方法可以参考我们做菌落pcr的方法,这个方法是采用少量的菌作为模板 然后加入pcr反应液,在pcr高温预变性的过程中菌细胞壁会裂解掉,dna和质粒都释放到溶液中作为模板参与扩增。 如果你有96孔深板(1-2ml)以及排枪Z好了,省事省时。牙签或者枪头挑菌挑一点点(只要沾到菌落就行,不要求大块,大块反而不好),96孔每孔加500ul培养液,挑96个,然后拿去摇菌,培养3-5小时,菌液就可以直接作为pcr的模板了。 只要引物好用,基本都可以扩出来的。我们鉴定阳性克隆都这样做, 你可以参考

Carbonnanomaterialsarenovelmanufacturedmaterials,havingwidespreadpotentialapplications.Adsorptionofhydrophobicorganiccompounds(HOCs)bycarbonnanomaterialsmayenhancetheirto... Carbon nanomaterials are novel manufactured materials, having widespread potential applications. Adsorption of hydrophobic organic compounds (HOCs) by carbon nanomaterials may enhance their toxicity and affect the fate, transformation, and transport of HOCs in the environment. In this research, adsorption of naphthalene, phenanthrene, and pyrene onto six carbon nanomaterials, including fullerenes, single-walled carbon nanotubes , and multiwalled carbon nanotubes was investigated, which is the first systematic study on polycyclic aromatic hydrocarbons (PAHs) sorption by various carbon nanomaterials. All adsorption isotherms were nonlinear and were fitted well by the Polanyi-Manes model (PMM). Through both isotherm modeling and constructing “characteristic curve”, Polanyi theory was useful to describe the adsorption process of PAHs by the carbon nanomaterials. The three fitted parameters (Q0, a, and b) of PMM depended on both PAH properties and the nature of carbon nanomaterials. For different PAHs, adsorption seems to relate with their molecular size, i.e., the larger the molecular size, the lower the adsorbed volume capacity (Q0), but higher a and b values. For different carbon nanomaterials, adsorption seems to relate with their surface area, micropore volume, and the volume ratios of mesopore to micropore. Quantitative relationships between these sorbent properties and the estimated parameters of PMM were obtained. These relationships may represent a first fundamental step toward establishing empirical equations for quantitative prediction of PAH adsorption by carbon nanomaterials and possibly other forms of carbonaceous (geo-) sorbents, and for evaluating their environmental impact. In addition, high adsorption capacity of PAHs by carbon nanotubes may add to their high environmental risks once released to the environment, and result in potential alteration of PAHs fate and bioavailability in the environment. 展开

Microbial mapping The intensity of resonance Raman spectra of Cyt c allows for integration times below one second. Microbial mapping of an area of 50×50 μm2 with a resolution of 500 nm/pixel (10,000 single spectra) can be performed in less than 3 h. A further reduction of the measuring duration by a factor of 10 can be achieved by utilisation of an EMCCD camera (Coates et al., 2004). Microbial mapping was done on granules from two different sequencing batch reactors (SBR) (Gaul et al., 2006). The SBRs are used to analyse control parameters for the anaerobic ammonium oxidation. Fig. 7 shows two different microbial colonies in the same granulum. A graphical analysis of the spectroscopic data at 750 cm-1 (dominant resonant Raman band of Cyt c) and 2900 cm-1 (CH stretching mode) differentiated the two colonies. One colony shows stronger Raman signals at 750 cm-1 (blue frame). Whereas the other microorganisms have more amount of methyl or methylene groups (yellow frame). After the graphical analysis above, an average spectrum was constructed for each colony. The resulting averaged spectra were transferred to our Raman database of wastewater bacteria created by OPUS. The software recognized the microorganisms Fig. 5. Time series of N. eutropha Nm 57 which is captured by optical tweezers. Time difference between spectra: 1 s; Laser power: 9 mW. The bleaching effect due to photo-dissociation caused by laser radiation is easy to see. Fig. 6. The spectral heterogeneity of hierarchical clusteringis strongly dependent to the integration time. Bacteria from the same strain are only groupedtogether if the exposure time was the same. 246 R.

Follow the system installation instructions carefully and in the specified order. The software must be installed on the computer before connecting the USB cable. 2.1 Facilities Requirements Facilities requirements for the alpha-SE system are listed in Table 2-1 and the system dimensions are given in Fig. 2-1. As shown in Fig. 2-2, the alpha-SE tool requires a clear work area of 20 by 18 inches (500 by 460 mm), excluding the operator computer. 2.2 Unpacking the Hardware Opening the Shipping Container Move the alpha-SE shipping container to the area where the tool will be installed. Open the container and remove the top and side pieces of packing foam. Carefully remove all smaller components from the shipping container, verifying that you received all components, as shown in Fig. 2-3. Finally, remove the alpha-SE ellipsometer and position it on your clear 20” by 18” (510 by 460 mm) workspace. Caution: The alpha-SE ellipsometer without sample chuck weighs approximately 37 lbs. (16 kg.). Please find an assistant to lift the alpha-SE unit out of the shipping carton and on to clear work surface. 展开
