โœฆ Synopsis

The effects of initial osmotic pressure (IOP) on the production of ginseng polysaeeharide and ginseng saponin were studied in suspension cultures of Panax notoginseng cells. At higher IOP, the specific saponin production and intraceUular carbohydrate storage were increased, while the plant cell volume, the consumption rates of major medium components and the specific cell growth rate were decreased. The specific production of polysaccharide was reduced with an increase of IOP from 4.45 to 5.18 atm, and levelled off at an even higher IOP.

In this work we studied the production of betalains by suspension culture of Beta vulgaris. The 8. vulgaris grew at a doubling time of 4.8 days. The betalains production was found to be not-growth related.. The culture's response to different carbon sources was investigated. Best growth and pigment

Cell suspension cultures of Digitalis thapsi were grown in Murashige and Skoog medium under continuous light. The effects of the absence of CaCl2, elevation of the MnSO4 concentration from 0.1 mM to 5 mM or the addition of 100 ฮผM LiCl on their growth and digoxin production were investigated. The eli
