The main river in Beijing is the Yongding River. Nevertheless, According to the environmental contamination induced by economic growth, the environment of water, and the shore of the Yongding River are in danger of destruction. The Yongding River ecological repair is crucial. Phytoremediation and microbial remediation have constructed specific accomplishments in the contamination management aspect of river, while both have some advantages and some disadvantages. Using in the best way of the related advantages relies on the collocation and composition of microbes and plants. According to the search domain and past literature, we have presented the procedure of plant microbe-associated bioremediation for restoring the environment of the water and removing heavy metal contamination in the soil of the Yongding River. This study presents novel concepts and procedures for repairing the Yongding River ecologic environment.

Arsenic occurs naturally in the environment, but its uncontrolled liberation from industrial effluents has been imposing adverse effects on the environment. The continuous exposure of the soil is a matter of concern in this study. The soil consortium contains bacterial colonies that resist and adapt the metal toxicants and can in turn help in the bioremediation of such metals from the soil. This study stresses the isolation of arsenic resistant bacteria from the arsenic-contaminated soil. The Soil Sample was collected from the Sanganer area of Jaipur, Rajasthan. The soil in this area received the textile discharge from the industries located nearby. Four arsenic resistant bacteria were isolated from the sample which showed a high tolerance level towards arsenic and was able to grow in the presence of arsenic in-vitro. The Minimum inhibitory concentration was also determined for the strains against arsenite. The highest MIC was found to be 16mM of arsenite, which concludes tolerable limits of the strains. The Biochemical and Morphological characterization of the isolates was also conducted. The Four isolates also showed resistance towards various other metals like cadmium, cobalt, lead, zinc, mercury, chromium, and tin. The isolates on biochemical characterization were found to belong to the following Genus: Moraxella, Azomonas, Acetobactor and Corynebacterium. This resistance capacity of the isolates depicts their potential to bioremediate the toxicity of the arsenic in the environment.
