Studies on integrated approach of garcinia cambogia washwater treatment Co2 reduction and lipid production using microalgal species

Abstract

Countries in the entire world are suffering through several environmental issues among which water pollution, global warming and conventional energy depletion are the major concern of the society. The exploitation in the environment continues even if stringent laws are imposed towards protecting the environment. This exploitation leads to detrimental effects for the living being with regard to health and economy. In the present world where all the developing countries like India are heading towards tremendous industrial development with the advent of technology and innovation, the effluent management is still a problem which need to be addressed and it is quite indispensable to have a sustainable green environment. Hence, the world is looking at a technology that could fight against these problems that is sustainable and environmental friendly towards protecting the health, environment and economy. The microalgae based water treatment is gaining importance in recent years as it serves multiple purposes of which includes wastewater treatment, CO2 reduction and lipid production. Garcinia cambogia (G. cambogia), a Malabar tamarind is a tropical fruit and the active ingredient Hydroxy citric acid is popularly used as a weight-loss supplement. After extraction of the Hydroxy citric acid, the washwater of G. cambogia is considered as an effluent in industries. This contaminated washwater is generated at a significant quantity during extraction of hydroxycitric acid from G. cambogia and it represents a serious environmental concern when discharged without proper processing. However, this G. cambogia washwater can be used as a low-cost source of nutrients for microalgal growth newline
