Fig. 2. D. candidum protocorm suspension culture in 3 l balloon type bubble bioreactor containing 2 l MS medium with 0.05 mg l
−1 NAA, 2.5% (w/v) sucrose, 5:25 mM NH4:NO3
and 1% (v/v) banana homogenate: (A) accumulation of biomass, (B) changes in electrical conductivity and hydrogen ion concentration, (C) production of polysaccharides and
coumarins, (D) production of polyphenolics and flavonoids. Data are presented as the means ± standard error for three independent experiments.
