In the present study, Chlorella sp. was grown in volume-graded industrial wastewater and showed increased growth in 10% and 30% of wastewater but the maximum growth was shown in 100% industrial wastewater. Among nitrogen sources, maximum growth was observed in urea (6.80×105 cells/ml) while the least was determined in NH4Cl (1.40×105 cells/ml). The maximum no. of algal cells (2.50×105) was determined in 0% NaCl while the minimum cells were determined in 2% NaCl (0.002×105). The optimum algal growth was determined at pH 7 (7.0×105 cells/ml) but at pH 9 the alga showed significant growth (5.9×105 cells/ml). The alga showed resistance towards erythromycin and chloramphenicol but was sensitive against ampicillin and gentamicin. Alga showed high growth in the presence of Cd and Pb (5µg) while less growth was determined in the presence of Hg, Cu, and Cr (5µg). Different compounds including cyclotetrasiloxane, octamethyle-, cyclopentasiloxane, decamethyle-, cyclohexasiloxane, dodecamethyle-, cycloheptasiloxane, tetradecamethyle- and benzeneethaneamine were isolated and analyzed by GC-MS analysis.. Siloxanes have great significance in industrial products, especially in cosmetics and textile industries. Besides biofuel production alga has great potential to be used for various industrial products.

“…Smaller size particles have bigger surface regions which improves extraction performance and increases efficiency. Humidity has an effect on SFE, because it affects the execution of SC‐CO 2 by stopping the limiter that needs drying earlier to extraction 290. Adding chemical additives and modifiers and increasing the flow rate can reduce the extraction time.…”

Supercritical carbon dioxide (SC‐CO2) is CO2 that is stored beyond its critical point of 7.4 MPa and 31.1 °C. Given the request for consumption of a green solvent for the environment, SC‐CO2 is widely utilized in chemical, food, and pharmaceutical industries. To design material and drug production processes using supercritical fluid (SCF) technology, knowledge of their solubility is important. Temperature and pressure are the main factors in the study of solubility. Solubility data are then evaluated using equation of state, semi‐empirical, and intelligence models to establish suitable correlations. SC‐CO2 is one of the most important materials used in SCFs to study solubility. Another application of SC‐CO2 is in the field of material extraction to reduce the consumption of organic solvents. Nanoparticles production in drug industry is another advantage of SC‐CO2. Micro and nanoparticles can be produced using SCF techniques. In this review, the applications of SC‐CO2 in drug solubility, extraction of valuable materials, and nanoparticles production for pharmaceutical processes are reported and discussed. Finally, the main challenges are explained.
