DESCRIPTION:Speakers: Marcel A.K. Jansen (1School of Biological\, Earth an
 d Environmental Sciences\, University College Cork\, Cork\, Ireland 2Susta
 inable Institute\, University College Cork\, Cork\, Ireland)\nInnovative c
 ultivation techniques are required for new circular economy applications t
 hat require cultivation of large surface areas of duckweed under indoor co
 nditions. To increase duckweed cultivation area relative to floor space\, 
 multilayered cultivation systems have been developed. In these stacked sys
 tems\, duckweed is cultivated on liquid medium\, an approach inspired by t
 he natural\, floating habit of these aquatic plants. LEDs are sandwiched b
 etween each cultivation layer to provide homogenous light conditions. Stac
 ked systems can successfully generate large amounts of duckweed biomass\, 
 but their construction involves an engineering challenge due to the sheer 
 weight of the water column and associated mechanical support structures. A
 s a result\, most stacked systems comprise less than 10 cultivation layers
 . As an alternative\, growth of duckweed in a mist of nutrient-supplemente
 d fine droplets\, i.e. fog-o-ponics\, was pioneered. The advantage of fog-
 o-ponic cultivation of duckweed is that trays with water are omitted and r
 eplaced by a thin layer of fabric on which the duckweed is positioned. Fog
  droplets pass through the hydrophobic fabric\, to be returned to the mist
 er\, creating a circular flow-thru system. The use of fabrics substantiall
 y decreases the weight and thickness of each layer of duckweed in a stacke
 d fog-o-ponic cultivation system\, and as a consequence enables increases 
 in the number of duckweed layers per unit of floor space. Lemna minor was 
 grown in a fog-o-ponic system comprised of 10 cultivation layers in an inc
 ubator of just 40 cm height\, demonstrating good growth and an attractive 
 metabolic profile\, as well as upscaling potential.\n\nhttps://indico.unin
