Description |
Callus culture of Dioscorea deltoidea produced diosgenin and sterols during
stationary phase. Ammonium nitrate (420 mg Nitrogen/l) as sole nitrogen source
supported better growth than a combination of ammonium nitrate and potassium
nitrate (totally equivalent to 840 mg Nitrogen/l). The production of diosgenin
increased under low phosphate concentration (100 mg/l) whereas high phosphate
concentration (240 mg/!) promoted growth. Micronutrients, when used at 1ı89
strength, enhanced growth and diosgenin production. Depletion of nitrogen
increase in the diosgenin synthesis by a factor of 2. Adoption of a two stage
culture method enhanced the diosgenin production in cultured cells by eight-fold.
