Magnetite nanoparticle-assisted start-up of microalgal-bacterial granular sludge
Shotgun metagenomic sequencing data from microalgal-bacterial granular sludge cultivated in photo-sequencing batch reactors with different Fe3O4 nanoparticle dosages (0, 10, 50, and 100 mg/L). The project investigates how magnetite nanoparticles affect granulation, nutrient removal, and microbial community composition during MBGS start-up.
