DESCRIPTION:Speakers: Jingrou Chen (University College Cork\, Ireland)\n*L
 emnaceae* (duckweeds) and *Azolla*\, are floating aquatic plants\, that ex
 hibit rapid growth in nutrient-rich waters and have considerable potential
  for biomass production using wastewater derived nutrients. This study eva
 luated *Lemna* species and *Azolla filiculoides* (*Azolla*) growth perform
 ance on industrial meat processing effluent under controlled laboratory co
 nditions. Growth effects of agitations (0\, 30\, 60\, 90\, 120 rpm) and su
 rface covers (10\, 20\, 40\, 80%) were investigated over 7 days (Exp.1)\, 
 followed by continuous cultivation of *Azolla* under different hydraulic r
 etention times (HRT\; 3\, 5\, 7 days) at 10% surface cover for 15 days (Ex
 p.2). *Lemna minor* and *Lemna minuta* exhibited great growth at 60 rpm\, 
 achieving RGRs of 0.290 ± 11.34 day⁻¹ and 0.293 ± 2.23 day⁻¹\, res
 pectively. *Azolla* cultivated at lower-moderate surface covers at 60 rpm 
 achieved the highest RGR (20%: 0.10 ± 0.006 day-1). For Exp.2\, 3-day HRT
  supported greater growth (RGR: 0.067 ± 0.002 day-1) than 5- and 7-day HR
 Ts for 9 days. Findings provide insights into the development and optimisa
 tion of floating macrophyte-based phytoremediation systems and plant bioma
 ss generation.\n\nhttps://indico.unina.it/event/117/contributions/2953/
