细菌蛋白

The source of photoluminescence was discussed and we speculate that it was caused by fluorescence resonance energy transfer between the tryptophan of PrP and hematoporphyrin in the bacteria.

同时对荧光来源进行推理并——验证，最后推测导致朊蛋白有荧光的原因是，朊蛋白中的色氨酸与细菌中荧光小分子血卟啉发生荧光共振能量转移。

SDS-PAGE showed that the recombinant plasmid IPSE/pET32a expressed a fusion protein with an M r 35 700 after being induced by IPTG.

经IPTG诱导，SDS-PAGE分析，含重组质粒的转化子细菌能表达相对分子质量约35 700的蛋白分子，与预计Trx-IPSE融合蛋白的相对分子质量大小相符。

Those expression plasmid were respectively transformed into E.coli DH5a, thenthe expression strains were induced for 5h under 42℃, SDS-PAGE confirmed that interestprotein was expressed by pBV220-R- IFN-γ_m strain and was 16kd in size. Its contentaccounted for 38.6％of the thalline protein.

分别转化大肠杆菌DH5α，42℃诱导表达4h，经SDS-PAGE电泳鉴定，原核表达质粒pBV220-R-IFN-γ_m表达的目的蛋白大小为16Kd，占细菌总蛋白的38.6％。

Because the full length DFF45 recombinant protein was unstable in the solution, it means that either the DFF45 protein has uncompacted region in the structure or the protein has several domains.

由于细菌表达的全长DFF45重组蛋白表现出不稳定易降解的特点，说明该蛋白可能具有无固定结构的区域，或者含有多个结构域。

The values of D10 and D for the total bacteria in boiled dumplings under chill state were 2.04 kGy and 4.00 kGy, the value of D10 and D for E. coli were 1.25 kGy and 2.00 kGy. TBAS were increased significantly and excessed the trade standard by 5 kGy γ-irradiation. However, the TBAS would be decreased with addition of antioxidants. Lipid peroxide,volatile basic nitrogen,"a" value of color and "b" value of color showed a tendency of increase, and moisture content and Aw showed a tendency of decrease, which did not achieve a significant level(p.05) by 1 to 5 kGy doses of γ-irradiation. Total acidity, amino acid nitrogen and free fatty acid showed no significant differences between treated and control samples. Sensory evaluation values were decreased and were all well within the acceptable level by 1 to 5 kGy doses of γ- irradiation.

辐照能有效降低鲜熟水饺细菌总数和大肠菌群数量，鲜熟水饺中细菌总数和大肠菌群的 D10值分别为 2.04 kGy 和 1.25kGy，D 值分别为 4.00 kGy 和 2.00kGy；0～5kGy 辐照鲜熟水饺 TBA 值随辐照剂量增加而增加，5kGy 辐照已使之超过国家行业标准限量要求；辐照鲜熟水饺过氧化值、挥发性盐基氮、色差 a 值、色差 b值存在随辐照剂量增加而增加的趋势、水分含量存在下降趋势，但变化未达到显著水平(p.05)；对酸度、氨基酸态氮、水分活度、游离脂肪酸含量等其他理化指标没有显著影响；较高剂量辐照使产品感官质量降低，却都在可接受范围内； 4kGy 辐照使维生素 B1下降 31.94%，对维生素 E、蛋白、脂肪、氨基酸、不饱和脂肪酸含量无显著影响。

Young therefore suggests that many nanobacteria in the blood may be coated in albumin, and the test detected these.

约翰·杨由此认为血液中的许多纳米细菌的表面可能也包有一层清蛋白。该项试验也的确检测到了一些这样的纳米细菌。

Protamines inhibit or kill bacteria by destroying their cell wall, cell membrane and changing permeability of cytoplasm membrane.

鱼精蛋白主要是通过破坏细菌的细胞壁、细胞膜及改变细胞的渗透性等途径抑制甚至杀死细菌细胞。

Under the proper environmental conditions, the salt-loving bacterium Halobacterium halobium synthesizes a membrane protein (Mr 26,000) known as bacteriorhodopsin, which is purple because it contains retinal.

在适当的环境条件下，嗜盐细菌合成一膜蛋白(Mr26，000)称为细菌视紫红质，它是紫色的因为含视黄醛。

在适当的环境条件下，嗜盐细菌合成一膜蛋白(Mr26，000)称为细菌视紫红质，它是紫色的因为含视黄醛。

Bacteriorhodopsin in Purple Membrane Proteins Under the proper environmental conditions, the salt-loving bacterium Halobacterium halobium synthesizes a membrane protein (Mr 26,000) known as bacteriorhodopsin, which is purple because it contains retinal.

在适当的环境条件下，嗜盐细菌合成一膜蛋白(Mr 26，000)称为细菌视紫红质，它是紫色的因为含视黄醛。

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。
