Effect of the remaining glycerol in the metabolites deposition for the chlorella vulgaris utex 1803, through inmobilization techniques
AbstractThe 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
