The optimization of cell disruption is a critical step in microalgal biorefineries. We used the same batch Tetraselmis suecica culture to compare two mechanical techniques, focusing on extraction yield water-soluble molecules. conditions for high-pressure homogenization (HPH) studied were passes at moderate pressure 300 bars. For ultrasound (US) treatment, we an amplitude 20% (equivalent 100 W) 25 min. These chosen basis preliminary screen conditions. HPH extracted proteins and pigments more efficiently than US, whereas US was superior uronic acid extraction. Interestingly, methods had similar yields carbohydrates under also analyzed kinetics molecule release by considering centrifugation time lag applying first-order kinetic model US. outperformed terms immediate

Anthroponics: Application and effects on growth of parsley, rhipsalis, coriander, and basil fed with urine fertiliser

Desalination and Water Treatment, Journal Year: 2024, Volume and Issue: 320, P. 100682 - 100682

Urine has emerged as a promising nutrient-rich waste stream suitable for plant fertigation. Biological nitrification in membrane bioreactor offers an effective method producing liquid fertiliser from urine, extracting essential nutrients into final product. Despite the increasing interest hydroponics and urban horticulture, research exploring efficacy of urine-derived fertilisers remains scarce. This study employed three growing systems, including nutrient film technique open channels outdoor setup, pot-drench under glasshouse conditions, deep-water culture (DWC) laboratory conditions to investigate efficiency compared commercial fertilisers. The results demonstrated comparable growth responses parsley, rhipsalis, coriander, basil, by analysis several parameters biomass, stem numbers length, nutritional composition shoots roots. In conclusion, showed potential sustainable alternative synthetic fertilisers, laying foundation development circular economy agriculture.
