“…Approximately, 93.4, 97.8 and 98.4% were removed from the growth medium containing 10%, 20% and 30% of UWW respectively. 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].…”

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.

“…Evaluating the algae in a runway pool of which the volume was 950 L. It was found that the algae had potential to produce 9.2-17.8 tons biomass per hectare annually and the lipid content was 6.82%. Hongyang et al [31] cultivated Chlorella pyrenoidosa using soybean process wastewater without any additional nutrients in fed-batch culture. After 120 h, the alga was able to remove 77.8 %, 88.8% and 70.3% of soluble chemical oxygen demand, total nitrogen and total phosphate, respectively.…”

Abstract. Microalgae have great potential as the feedstock of renewable energy. Nevertheless, the high cost of microalgae cultivation hinders its development economically, so inexpensive cultural mediums are supposed to be found for the large-scale application of microalgae. Wastewater contains large amount of organic and inorganic compounds, which provides nutrition for the cell growth and lipid accumulation of microalgae. Here we will review the systems of microalgae cultivation and utilize wastewater as a feedstock for biodiesel production. It illustrates that the integration of microalgae cultivation and wastewater treatment could improve water quality and accumulate lipid simultaneously.

“…Importantly, the application of waste-derived organic carbon for mixotrophic or heterotrophic production of algal biomass, demonstrated by Abreu et al (2012), is likely to be the only economical substrate source for biofuel production. In fact, a number of species from Chlorella (C. vulgaris (Perez-Garcia et al 2010;Heredia-Arroyo et al 2011;Abreu et al 2012;Mitra et al 2012;Farooq et al 2013), C. sorokiniana, C. pyrenoidosa (Hongyang et al 2011;Wang et al 2012), C. protothecoides, C. minutissima, C. kessleri), Scenedesmus (S. obliquus (Hodaifa et al 2009;Zhang et al 2013), S. dimorphus, S. quadricauda, S. bijuga), Chlamydomonas (C. debaryana, C. globosa), and Micractinium genera have been reported to grow either mixotrophically or heterotrophically in various types of wastewater including municipal, sludge anaerobic digestion effluent, soybean or starch processing, brewery, ethanol thin stillage, piggery, dairy, and poultry media (Bhatnagar et al 2011;Park et al 2012;Bohutskyi et al 2015c). More specifically, the increase of carbohydrate was observed when Scenedesmus obliquus was mixotrophically cultivated in municipal wastewater supplemented with CO2 and food wastewater (Ji et al 2015).…”

The prospects of biofuel production from microalgal carbohydrates and lipids coupled with greenhouse gas mitigation due to photosynthetic assimilation of CO2 have ushered in a renewed interest in algal feedstock. Furthermore, microalgae (including cyanobacteria) have become established as commercial sources of value-added biochemicals such as polyunsaturated fatty acids and carotenoid pigments used as antioxidants in nutritional supplements and cosmetics. This article presents a comprehensive synopsis of the metabolic basis for accumulating lipids as well as applicable methods of lipid and cellulose bioconversion and final applications of these natural or refined products from microalgal biomass. For lipids, one-step in situ transesterification offers a new and more accurate approach to quantify oil content. As a complement to microalgal oil fractions, the utilization of cellulosic biomass from microalgae to produce bioethanol by fermentation, biogas by anaerobic digestion, and bio-oil by hydrothermal liquefaction are discussed. Collectively, a compendium of information spanning green renewable fuels and value-added nutritional compounds is provided.
