“…On the other hand, with Karanja biodiesel, the decrease of both emissions by 13.63% and 3.83% respectively and increase in BSFC upto 8.5%. Mao et al [21] investigated the performance, emission characteristics of 5% blend of Chlorella vulgaris biodiesel fuel in nonroad diesel engine. They found that 5% blend shows decrease in HC and CO than pure diesel except NOx at higher loads.…”

"Rapid depletion of petroleum reserves and the environmental concern demands the replacement of conventional fuel with renewable and alternate fuel to fulfill the demand of energy requirement. Biodiesel fits to be the good replacement in CI engine and extensive research has been done in the field of Biodiesel. In this work, the effect on performance and emission of using biodiesel in IC engine has been reviewed. The emissions of unburnt hydrocarbon, carbon monoxide and particulate matter can be reduced considerably with the use of biodiesel compared to diesel fuel. There is some shortcoming by using of Biodiesel such as high brake specific fuel consumption, lower brake power and brake thermal efficiency, which can be overcome by using supplement fuel like hydrogen along with biodiesel. Further, the review work has been extended to methods of hydrogen production and its usage as a secondary fuel along with biodiesel in the engine.

“…C. vulgaris is reported to havea pro cient ability to removebiological oxygen demand (BOD), chemical oxygen demand (COD), phosphorous and nitrogen-based pollutants from wastewaters within short periods (Azizi et al 2020). Previously, various successful studies have been done on the bioremediation e ciency of C. vulgaris using different types of wastewaters such as domestic (Miao et al 2016), municipal (Znad et al 2018), synthetic (Lee et al 2020), and petrochemicaland textile (Subashini and Rajiv 2018) wastewaters.Algal biomass isa rich source of lipids, proteins, pigments, and vitamins which can be utilized in various applications such as making nutrition supplements, food products,pharmaceuticals.Along with phycoremediation application, algae are also known for their lipid production e ciency (Mao et al 2020).Recently, algal lipids are in great demand for the production of biofuels having good fatty acid pro les (Hess et al 2018;López et al 2019).…”

The efficient management and treatment of pharmaceutical industry wastewater (PIWW) have become a serious environmental issue due to its high toxicity.To overcome this problem, the present study deals with the phycoremediation of PIWW using Chlorella vulgaris microalga isolated from the Ganga River at Haridwar, India. For this, response surface methodology (RSM) and artificial neural network (ANN) tools were used to identify the best reduction of total phosphorus (TP) and total Kjeldahl’s nitrogen (TKN) based pollutants along with lipid production efficiency of C. vulgaris. Three different concentrations of pharmaceutical wastewater (0, 50, and 100%), operating temperatures (20, 25, and 30°C), and light intensity (2000, 3000, and 4000 lx)were used to design the phycoremediation experiments. Findings revealed thatC.vulgaris was good enough to remove maximum TP (90.35%), TKN (83.55%) along 20.88% of lipid yield at 25.62℃ temperature, 60.73% PIW concentration, and 4000 lx of light intensity, respectively.Based on the model performance and validation results, ANN showed more accuracy as compared to the RSM tool. Therefore, the findings of this study showed thatC.vulgarisis capable of treating PIWW efficiently along with significant production of lipid content which can further be used in various applications including biofuels production.

“…Biodiesel is composed of a combination of fatty acid alkyl esters [16]. Lipid content and the fatty acid profile are noticeable factors in algae cultivation [17]. Microalgae species contain proteins, pigments and vitamins, and lipids, which have applications in cosmeceuticals, nutraceuticals, fine chemicals, pharmaceutics, and biodiesel [18,19].…”

A novel strategy of using microalgae Chlorella vulgaris for simultaneous bio-treatment of petrochemical wastewater and lipid production was developed in the present study. Phycoremediation was carried out in 30 days. The profile of fatty acids was identified, and the specifications of biodiesel including saponification value, iodine value, cetane number, long-chain saturated factor, cold filter plugging point, cloud point, allylic position equivalent and bis-allylic position equivalent were predicted by BiodieselAnalyzer® software. Besides, polycyclic aromatic hydrocarbons were determined in both wastewater samples and produced lipid. The observed data showed that biodiesel from C. vulgaris was superior to petrodiesel in terms of suitability in diesel engines. Moreover, contamination of petrochemical wastewater can influence the expression of a variety of genes in algae. To investigate the effectiveness of contamination on the expression of lipid synthesis as well as three photosynthesis genes, a real-time polymerase chain reaction assay was used to quantify transcript levels of PsaB (photosystem I reaction center protein subunit B), psbC (an integral membrane protein component of photosystem II), and rbcL (a large subunit of ribulose-1,5-bisphosphate carboxylase oxygenase). Furthermore, the gene expression level of accD (acetyl-coenzyme A carboxylase carboxyl transferase subunit beta, chloroplastic) was studied to discover the effect of wastewater on lipid production. The results showed that when diluted petrochemical wastewater (50%) was used as a media for C. vulgaris cultivation, these genes expression significantly increased. For 50% diluted wastewater, the maximum removal of BOD, COD, total nitrogen, and total phosphor has been 30.36%, 10.89%, 69.89%, and 92.59%, respectively.
