Abstract

ARDILA-ALVAREZ, Ana María et al. Effect of the remaining glycerol in the metabolites deposition for the chlorella vulgaris utex 1803, through inmobilization techniques. Iteckne [online]. 2017, vol.14, n.1, pp.17-23. ISSN 1692-1798.

The purpose of the present study was to evaluate the viability of glycerol as carbon source using immobilized algae coupled with a modification on nitrogen (NO₃^-) and phosphate (PO₄) concentration, for the production of high valuable compounds (carbohydrates, proteins and lipids). The best conditions for carbohydrate accumulation were found by statistical analysis and they were achieved within a 3-5% (v/v) glycerol and an initial concentration of nitrogen source of 0,37 (g/L). Lipid deposition was favored with a concentration of 3% (v/v) glycerol and 0.04 (g/L) nitrogen. On the other hand, proteins were favored with higher concentrations of glycerol (5% v/v) and a concentration of nitrogen similar to that used for carbohydrates.

Keywords : Glycerol; inmobilization; chlorella vulgaris.
