In Vitro Cell. Dev. Biol.-Plant

Hairy root cultures of Artemisia annua L. were cultivated in three different mist bioreactors, each fitted with three stainless steel meshes. The growth rates in the three 2.3-L mist bioreactors differed. After 25 d, the growth index (final dry weight/initial dry weight) of the roots was 42 in a nutrient mist bioreactor, 61 in an inner-loop nutrient mist bioreactor; and 68 in a modified inner-loop nutrient mist bioreactor. Under a misting cycle of 3/30 (ON 3 min/OFF 30 min) for 25 d, dry weight reached 13.6 g/L of medium in the modified inner-loop nutrient mist bioreactor in which nutrient could be supplied without dilution of mist tv air flow.Hairy root cultures of Artemisia annua L. were cultivated in three different mist bioreactors, each fitted with three stainless steel meshes.
