“…Hongyang et al, [45] reported the removal of nitrogen (77.8%) and phosphorous (88.8%) from soybean processing wastewater using Chlorella pyrenoidosa. C. vulgaris grown in tertiary municipal wastewater with initial concentration of 8.7 and 1.71 mg·L −1 of total nitrogen and phosphorous has completely removed the nutrients at the end of 4 days cultivation [46]. In other studies, removal rate of total nitrogen was observed between 61.1% -91.8% by Chlorella sp.…”

Urban wastewater contains both organic and inorganic nutrients and discharge of untreated water increases nitrogen and phosphorous content in water bodies leading to eutrophication problem. Physical and chemical treatment of urban waste water produces large quantities of waste sludge associated with secondary pollution. Microalgae can assimilate nutrients especially nitrogen and phosphorous from wastewater for their growth and produce valuable biomass and lipid. This study was performed to determine the growth of Chlorella vulgaris in urban wastewater (UWW) and Bold's basal medium (BBM) thereby identifying cost effective growth medium for microalga cultivation. In addition, nutrient removal abilities of C. vulgaris from various dilutions of urban waste water were explored at 10 days cultivation period. Specific growth rate, biomass and lipid content were higher in microalgae grown in urban waste water than BBM. The highest lipid productivity of 14.31 mg· L −1 ·day −1 was achieved in the culture grown in UWW medium which exceeded the BBM at 1.15 fold. The amount of nutrient removal tended to increase with higher dilutions of UWW. Removal rates of upto 87.9% and 98.4%were recorded for total nitrogen and total phosphorous by C. vulgaris. The results emphasized that urban waste water as a cost effective growth medium for higher biomass and lipid production accompanied with the nutrient removal efficiency of microalgae to reduce eutrophication.

“…However, all four microalgae were able to remove 100 % of NH 4 -N and 43-54, 83-95 and 70-92 % of NO 3 -N, NO 2 -N and PO 4 -P, respectively, after 3 days in the batch reactor (Table 4). Ji et al (2013) studied the biomass production and nutrient removal potential of Chlorella vulgaris, Scenedesmus obliquus and Ourococcus multisporus in tertiary treated municipal wastewater. All the studied microalgae removed more than 99 % of the nitrogen and phosphorus in 4 days.…”

Discharge of untreated domestic and industrial wastewater into aquatic bodies is posing a serious eutrophication threat, leading to a slow degradation of the water resources. A number of physical, chemical and biological methods have been developed for the treatment of wastewaters; among these, the use of microalgae is considered as a more eco-friendly and economical approaches. Microalgae are versatile organisms which perform multiple roles in the environment-bioremediation of wastewater, gleaning of excess nutrients and in turn, generate valuable biomass which finds applications in the food, biofuel and pharmaceutical industries. They are currently being utilized to reduce the high nutrient load (especially N and P) from wastewaters, which fulfill the growth requirements of microalgae, making it a suitable cultivation medium for biomass production. The present review represents a comprehensive compilation of reports on microalgal diversity of wastewaters, followed by a critical overview of their utilization, suitability and potential in bioremediation vis-a-vis biomass production. This review also emphasizes the superiority of polyalgal and consortial approaches in wastewater treatment, as compared to the use of unialgal inocula, besides providing useful pointers for future research needs in this area.

“…Potentials of the microalgae cultivated in municipal wastewater effluent in batch and continuous mode have been reviewed. Many previous studies have reported the treatment of industrial, municipal and agricultural wastewater by micro algal culture systems (Franchino et al, 2013;Ji et al, 2013;Lau et al, 1995;Lau et al, 1998;McGinn et al, 2012;Singh et al, 2012;Srinivasan & Subramaniam, 2009;Talbot & delaNoue, 1993;Tam & Wong, 1989;Williams, 2003). Such type of schemes has significant applications in the reduction of nutrient release in associated streams by assimilatory uptake of nitrogen that in turn decreases the rate of eutrophication of receiving streams and also provides oxygen for nitrification and biological organic matter oxidation (Kothari et al, 2013;Mata et al, 2010;Park et al, 2010;Wolanski et al, 2009).…”

The present study investigates the possibility of integrating an existing industrial large scale biomass production with the treatment of waste water in which a mixture of organic and inorganic rich pollutants was used as a medium. This study suggests that the replacement of a defined medium with a complete mixotrophic medium gives a significant statistical difference in terms of growth parameters i.e. biomass production and specific growth rate.The green microalga C. pyrenoidosa was cultivated under different mixotrophic conditions for evaluation of biomass production. Inorganic defined fog's medium supplemented, with raw dairy wastewater led to 1.37g/L biomass production in comparison to 1.2g/L obtained with pure glucose revealing 14.16% increase. The study also involves the supplementation of raw dairy wastewater as an organic carbon source in an inorganic medium comprising municipal treated water and reverse osmosis (RO) treated wastewater and attained 2.4g/L and 1.6g/L of biomass respectively, as compared to 0.3g/L and 0.16g/L obtained in the wastewaters alone revealing 700% and 900% increase respectively. Mixotrophic regimen cells as analyzed by a 2D Fourier transform infrared (FTIR) spectroscopy for its biochemical content revealed that fog's blended raw dairy waste (RDW) regimen cells had maximum
