(2016-05-20) Blanco Suarez, Vanessa E.; Villamizar Sanchez, Susan S.; Peralta Ruiz, Yeimmy Yolima; González-Delgado, Ángel Darío; Barajas Solano, Andrés Fernando; Ardila Álvarez, Ana María
The aim of the present study is to evaluate the viability of glycerol as carbon source on immobilized algae cultures coupled with a modification on nitrogen (NO3-) and phosphate (PO4) concentration for the production of high valuable compounds (carbohydrates, proteins and lipids). it was determined that the conditions who favour the deposition of carbohydrates are 3-5% (v/v) of glycerol and 0.37 (g/L) of NaNO3. On The other hand, for obtain higher amounts of lipids, a 3% (v/v) of glycerol coupled with a limitation in the nitrogen source (0.04 g/L) are needed. Finally, in order to improve deposition of total proteins, larger concentrations of glycerol (5% v/v), NaNO3 (>0.37 g/L) and phosphate are needed.
