Abstract- The accumulation of wastes of domestic and industrial processes in the nearby water bodies results in water pollution. The wastewater discharged into the water bodies are hazardous to environment and cause various health problems in human beings. Eutrophication is one such major environmental problem caused due to the discharge of nutrient rich wastewater into the nearby water bodies. Excessive pollutants including nutrients affect aquatic live sand environment in various ways. There are certain plants capable of removing pollutants from water. Phyto remediation is an alternate way to reduce nutrients from contaminated medium. Microalgae can be used for phytoremediation to reduce the nutrient content in the waste water due to the algae’s ability to assimilate nutrients into the cells. The microalga Chlorella vulgaris can utilize the nitrogen and phosphorus in wastewater for its growth. Hence in the present study, microalga Chlorella vulgaris was used to determine the removal efficiencies of pollutants, such as chemical oxygen demand (COD), total nitrogen (TN) and total phosphorus (TP). The Chlorella vulgaris was cultured in the shake flasks that contained wastewater in the presence of artificial light in the laboratory. It removes the maximum percentage of TN and TP were within 82.1% and 90.9%, respectively. The Chlorella vulgaris which could not only bioremediate the waste water, butyl so produce plenty of the microalga biomass that could be used for the exploitation of fertilizers, feed additives and biofuels. The optimum detention period for the maximum phytoremediation is found to vary within 10 and 14 days. Based on the laboratory scale study under controlled environment, it can be concluded that Chlorella vulgaris has the potential to reduce nutrient content of waste water.

Abstract- India boasts a drastically rich variety of flora, many of which are of medical importance and unfortunately are disappearing fast from our rich resource due to over-exploitation. Thus, it has become urgent to manage the traditional medicinal plant resource. There is a greater demand for uniform medicines made from medicinal plants, which requires mass propagation of crops. This is done through plant tissue culture strategies. Conservation and domestication of endangered and threatened species has become a very critical issue in a global perspective. Habitat destruction, fragmentation, and degradation plus human-wildlife conflict contribute to the extinction of many species. This review will give the reader an overview of the conservation and domestication status around endangered and threatened species, their successes and challenges. Future directions for conservation and domestication, including technology, community engagement, and policy support, are also discussed. The studies conducted were under the aegis of the setting up National Medicinal Plants Board (NMPB) New Delhi during 2002 2013 having in-situ and ex-situ conservation projects through diverse State Forest Departments. Besides, there were R&D projects carried out by the ICAR, ICFRE, CSIR, DBT, and SAUs. Contributions of NMPB have been highlighted in conservation and cultivation of endangered and threatened medicinal plant species in India. There are various causes for which these species get endangered in their own habitats like Habitat loss due to diversion of forest land, biotic and abiotic interference in forest areas, and Unsustainable harvesting of so-called medicinal and aromatic plants. Many projects have been funded by NMPB for conservation and cultivation of endangered as well as threatened medicinal plants.
