DESCRIPTION:Speakers: Sara Demaria (DISTAL\, Department of Agricultural an
 d Food Sciences\, Alma Mater Studiorum – University of Bologna\, Bol
 ogna\, Italy)\nNon-conventional crops with high nutritional value and effi
 cient resource use may improve food security while reducing environmental 
 pressures. Duckweeds are fast-growing aquatic plants with high potential a
 s alternative protein sources. However\, their ability to assimilate sever
 al compounds may imposes food-safety concerns. Controlled-environment agri
 culture (CEA) could reduce microbiological risks and accumulation of undes
 irable compounds\, but knowledge of indoor cultivation strategies remains 
 fragmented. This systematic review synthesized how growing conditions and 
 management affect duckweed growth and biochemical composition in indoor CE
 A. Four databases were searched for studies reporting growth and/or bioche
 mical outcomes. Responses varied among genera\, species\, clones\, and out
 comes\, preventing definition of common cultivation ranges. Most studies e
 xamined Lemna\, particularly Lemna minor\, in small-scale batch systems\; 
 semi-continuous\, recirculating\, photobioreactor\, and multilayer systems
  were uncommon. In Lemna\, nitrogen availability and source affected bioma
 ss and protein production\, while nutrient limitation and environmental st
 ress promoted starch or soluble sugar accumulation\, often reducing growth
 . Light intensity influenced biomass more consistently than composition. I
 n Spirodela\, red light and carbon availability promoted starch accumulati
 on\, while blue light increased amino acids and photosynthetic pigments. L
 andoltia showed consistent starch accumulation under nutrient limitation\,
  especially when combined with extended photoperiods. In Wolffia\, nutrien
 t availability influenced protein\, starch\, biomass nitrogen\, and nitrat
 e accumulation\, while evidence for Wolffiella was limited. Minerals\, und
 esirable compounds\, and microbiological safety were occasionally assessed
 . Evidence supports food-oriented production and shows that cultivation co
 nditions can direct biomass towards protein- or starch-oriented uses. Scal
 ing up cultivation alongside comprehensive nutritional and safety assessme
 nts is needed to develop standardized production strategies.\n\nhttps://in
