An Integrated Approach of Wastewater Mitigation and Biomass Production for Biodiesel Using Scenedesmus sp.

A critical review on phycoremediation of pollutants from wastewater—a novel algae-based secondary treatment with the opportunities of production of value-added products

“…The species were S. quadricauda, S. obliquus, S. acutus, S. abundans, etc. These species have been found to be useful for treatment of domestic, agricultural and industrial wastewaters (Arora, Tripathi et al 2019). In order to get a uni-algal culture, the desired species must be isolated from the mixed culture.…”

“…In order to avoid such controversial status, third-generation biofuels were developed. 3rd generation biodiesel was made by extracting lipids from algal biomass, thus, eliminating food and cultivable land utility concerns (Eladel, Esakkimuthu et al 2019), (Arora, Tripathi et al 2019). Biodiesel produced from food crops like palm oil, soybean oil, and rapeseed oil suffers various limitations in terms of reliability of the oil produced and the "food versus fuel" debate.…”

“…Closed PBR overcome the disadvantages of open systems, by allowing better control of the different parameters affecting growth and preventing contamination. This is of advantage when high quality, complex byproducts are to be obtained from algal strains(Arora, Tripathi et al 2019). Although for fragile systems closed systems are preferred yet diversity is lost in closed systems as compared to open systems(Sahu, Sahoo et al 2019).…”

“…Organic contaminants and total phosphorous were removed almost completely, also the highest biomass productivity was observed. The catalogued and identi ed tolerant algal species that can be used against different harmful wastes were found to be Scenedesmus, Euglena, Chlamydomonas, Nitzschia, Oscillatoria, Chlorella, Stigeoclonium and Navicula(Arora, Tripathi et al 2019). Madadi et alon how tanneries turn animal hides into leather through a series of complicated processes that use a lot of water and chemicals like lime, ammonium sulphate, sodium sulphide, sodium chloride, and chromium salts are aplenty in the literature(Mukherjee, Okolie et al 2019).…”
