JIMENEZ R, Silvia L et al. CELLULAR SUSPENSIONS ESTABLISHMENT OF Bixa orellana L., PHENOLIC COMPOUNDS PRODUCERS WITH POTENTIAL ANTIOPHIDIC ACTIVITY. Vitae [online]. 2008, vol.15, n.1, pp.70-76. ISSN 0121-4004.

A protocol for production and massification of achiote cells in suspension from friable calli of leaf tissues, has been developed as a strategy to obtain antiophidics metabolites, especially phenolics compounds. Concentration effects of, inoculum, glucose, phosphorus and nitrogen, on cellular growth kinetics were evaluated in ½ MS+2,4-D (5 ppm)+BAP (1 ppm) medium, stored at 25º C, darkness and 140 rpm, using a randomized factorial design with 4 factors, two levels and evaluation at 20 and 40 days of establishment. Treatment with highest biomass production of achiote cells in suspension, had an initial biomass concentration of 4g/l, glucose 20g/l, phosphorus 0,13g/l and nitrogen 2,52 g/l. Kinetics growth of achiote cells in suspension in culture conditions, presented a well defined exponential phase of 25 days, since then a stationary phase until the end of the evaluation (40 days). Total phenols contents among material obtained in-vitro and vegetable material obtained ex vitro were compared as a valid criteria to justify later works of in-vitro metabolic production in this vegetable specie.
