Hairy root cultures of Beta vulgaris L grown in a bubble column reactor were permeabilised by exposure to B5 medium of pH 2.0. The roots released 39% of their total pigments on a 10 min exposure to B5 medium of pH 2.0 followed by return to standard B5 medium. The pigments released in the extracellular medium were recovered on an adsorption column containing XAD-16 resin. The permeabilised roots regrew and accumulated additional pigments. Comparison of this technique with the previously used techniques like oxygen starvation and temperature shock to permeabilise beet hairy roots suggest that pH mediated release of betalains can be an effective method of releasing betalains from root cultures.
