细菌的

An antibiotic obtained from the actinomycete Streptomyces erythreus; effective against many Gram-positive bacteria and some Gram-negative.

Understanding these relationships will help find ways of thwarting their attacks and using them to clean up pollutants.

如果能够了解它们之间的关系，科学家们就能够找出方法来抵挡细菌的进攻，或者利用细菌来分解污染物。

Five different selective culture medium were used for sewage microorganisms directional isolated cultivate, advantage compound bacteria of photosynthetic bacteria, ammonifying bacteria, nitrifying bacteria, denitrifying bacteria and phosphate solubilizing bacteria could be gained through enrichment cultivate, then compounded them and used in test wastewater static treatment.

采用5种选择性培养基对水样中的微生物进行定向分离，通过富集培养，可以得到光合细菌、氨化菌、硝化菌、反硝化菌和磷细菌的优势菌群，进行复合后，再对试验污水进行静态处理。

Ammonifying rate, nitrosifying rate,nitrifying rate and denitrifying rate were determined by measurement of conversion efficiency and accumulating rate of nitrogenous matter by ammonifying bacteria, nitrobacteria, nitrifying bacteria and denitrifying bacteria in the surface 0-1.5 cm of pond sediment from the intensive fish culture ponds.

通过对精养鱼池表层淤泥中氨化细菌、亚硝化细菌、硝化细菌和反硝化细菌对含氮物质转化率的测定，定量了解了上述细菌的氨化率、亚硝化率、硝化率和反硝化率。

In-depth studies were carried out on the extracellular·OH scavenging effect of white rot fungus with various media conditions in the dynamic degrading process of lignocellulose, and on the correlation between·OH scavenging and lignocellulose degradation. The·OH scavenging efficiency of A3 reached 45%~50% significantly during biodegrading process.

对不同白腐菌、丝状真菌及细菌的木质纤维素基质液体培养体系，进行胞外·OH清除能力比较研究，结果表明：体系·OH清除能力在白腐菌类群中较为普遍，相对于细菌、丝状真菌等常见微生物群落则是较独特的，该能力与菌株木质纤维素降解机制及能力相关，受底物基质营养构成状况影响。

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。

If so, the new antibiotics would leave bacteria alive, but they'd basically be POWs.

如果确实如此，这些新的抗生素就会留下细菌的性命，但这些细菌基本上也就是战俘，已经无路可逃了。

If so, the new antibiotics would leave bacteria alive, but they'd basically be POWs.

如果确实如此，那么这些新的抗生素就会&饶过&细菌的性命，但是，这些细菌基本上也就是&战俘&而已，它们已经无路可逃了。

The cold resistance of floral organs was studied with different low temperatures treatments and INA inoculations.

花器官在不同低温及INA细菌处理条件下，研究花器官的抗寒性，结果表明：对照品种花器官褐变温度为-4℃~-5℃，而接种INA细菌的花器官褐变温度为-2℃~-3℃，与对照相比，花器官褐变温度提高2℃左右。

Archaean cell walls lack murein, a common component of bacterial cell walls, and their lipids have ether links rather than ester links.

古细菌的细胞壁缺乏细菌细胞壁组成的普遍物质-胞壁质，其连接是醚连接而不是酯连接。

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。
