ABSTRACT
Environmental problems are the most serious challenges in the 21st century. With the rapid development of modern industry and agriculture, ecological and environmental deterioration have become the most important factors to restrict the sustainable development of social economy. Microbial cells have strong ability for environmental remediation, but their evolution speed is slower than the speed of emerging pollutants. Therefore, the treatment using the synthetic biology is in urgent need. Full understanding of the microbial degradation characteristics (pathways) of refractory organic pollutants with the help of abundant microbial and gene resources in China is important. Using synthetic biology to redesign and transform the existing degrading strain will be used to degrade particular organic pollutants or multiple organic pollutants. For the complex pollutants, such as wastewater, based on the establishment of metabolic or regulation or resistance related gene modules of typical organic pollutants, artificial flora could be designed to solve the complex pollutants. The rational design and construction of engineering bacteria for typical environmental organic pollutants can effectively promote microbial catabolism of emerging contaminants, providing technical support for environmental remediation in China.
ABSTRACT
Objective:To explore the pharmacodynamic differences of india madder root before and after charcoal in antiinflammatory,ease pain,promoting blood circulation for removing blood stasis and hemostasis function.Methods: The india madder root and india madder root charcoal decoction pieces were processed by the same one operation,then the water decoction of them were given to the mouse by intragastric administration in different dosages.The method of auricle tumefaction was adopted to compare the antiinflammatory function,body wrings was adopted to compare the ease pain function,to compare the hemostasis function of india madder root before and after charcoal by snipping off the mouse’s tail and capillary method.Blood stasis model was made by injecting Dexamethasone Sodium Phosphate,then to compare the promoting blood circulation for removing blood stasis function of india madder root before and after charcoal of india madder root before and after charcoal.Results: India madder root decoction pieces is more effective than india madder root charcoal decoction pieces in antiinflammatory,ease pain,promoting blood circulation for removing blood stasis,but less effective in hemostasis.Conclusion: The function of antiinflammatory,ease pain,promoting blood circulation for removing blood stasis of india madder root were less effective after charcoal,but the fuction of hemostasis was more effective.
