Low cost mist bioreactors were designed to grow Artemisia annua transf
ormed roots and Dianthus caryophyllus shoots. The reactors use similar
mist generators but the culture chambers were modified to meet the re
quirements of each application. For root cultures grown in the mist re
actor, the ratio of the final to initial fresh weight was 7.4 after 24
days while for the shoots, the ratio was 10.8 after 14 days, Shoots g
rown in the mist had about half the hyperhydration of the controls gro
wn in culture tubes.
