研究的目的:

评估Rhodococcus ruber生物增量对使用可溶性SPW去化的影响.
为了确定R. ruber是否可以加速SPW组件的解以实现脱.

主要方法:

用少量Rhodococcus ruber (0.45%重/重) 生物增量去化生物质.
对酸盐- (NO3--N) 去除率的分析.
测量氨- (NH4+-N) 的释放量.
评估蛋白质和多糖的水解.

主要成果:

与未增加的生物质相比,R. ruber的添加加速了NO3 - N的去除率22%.
观察到NH4+-N的增强释放,表明SPW中氨基酸的分解增加.
R. ruber促进了SPW中蛋白质和多糖的更快的水解.

结论:

使用R.的生物增量有效地加速废水处理中的脱化.
R. ruber通过催化SPW中的蛋白质和多糖的水解来增强脱.
这项研究引入了一种新的方法,以改善WWTP中的去除.

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Overview of Nitrogen Metabolism

Overview of Nitrogen Metabolism

Nitrogen is a very important element for life because it is a major constituent of proteins and nucleic acids. It is a macronutrient, and in nature, it is recycled from organic compounds and stored in the form of ammonia, ammonium ions, nitrate, nitrite, or nitrogen gas by many metabolic processes. Many of these metabolic processes are carried out only by prokaryotes.
The largest pool of nitrogen available in the terrestrial ecosystem is gaseous nitrogen (N2) from the air, but this...
