This study presents an integrated strategy to optimize biofuel production from Chlorella sorokiniana (CSO) and vulgaris (CVU) by combining salt-induced stress thermal pretreatment. The microalgae were cultivated in anaerobic digestate effluent (ADE) under non-stress conditions evaluate nutrient availability’s impact on biomass composition. Salt significantly enhanced lipid accumulation, with CVU exhibiting a 51.6% increase. Thermal pretreatment of at 90 °C for 10 h achieved the highest methane yield (481 mL CH4/g VS), outperforming CSO. Milder (40 4 h) more energy-efficient CSO, achieving 2.67%. Fatty acid profiles demonstrated species-specific biodiesel properties, CSO rich oleic (33.47%) offering oxidative stability cold flow performance, while showed higher polyunsaturated fatty content. research highlights economic viability using ADE as low-cost cultivation medium potential scalable pretreatments. Future should focus reducing energy demands processes exploring alternative induction methods further enhance yields. These findings offer valuable insights tailoring processing strategies maximize production, supporting sustainable economically viable dual systems.

Use of fossil fuels causes environmental issues due to its inefficiency and imminent depletion. This has led interest in identifying alternative renewable energy sources such as biofuel generation from photosynthetic organisms. A wide variety prokaryotic eukaryotic microorganisms, known microalgae, have the potential be economical ecologically sustainable manufacture biofuels bio-hydrogen, biodiesel, bio-oils, bio-syngas. By using contemporary bioengineering techniques, innate algae produce biomass superior quality may enhanced. In algal biotechnology, directed genome modification via RNA-guided endonucleases is a new approach. CRISPR/Cas systems recently been frequently used modify genetic makeup several aquatic freshwater microalgae. The majority research Cas9-driven Type II system, one two classes six unique kinds CRISPR systems, specifically target desired genes algae, knock them out down, or both. Using technology makeup, microalgae produced more increased lipid content. review highlights attempts made so far modification, discusses prospects for developing platform large-scale identifies opportunities challenges development distribution CRISPR/Cas9 components.
