gamma-Linolenic acid production from Spirulina platensis
1995
Mahajan, G. | Kamat, M.
Various Spirulina strains were assayed for their productivity of gamma-linolenic acid (gammaLnn). Spirulina platensis ARM-346 was found to accumulate large amounts of gammaLnn. Urea as a nitrogen source was found to be most effective giving a yield of 13.5 mg gamma/Lnn/g dry cell mass. With increase in temperature the gammaLnn content was found to increase along with biomass. The optimum temperature for maximum gammaLnn and biomass production was found to be 35 degrees C. The gammaLnn content was highest at 0.06% (w/v) NaCl and 0.07% (w/v) K2HPO4. Cells cultivated in the orange region of the electromagnetic spectrum as energy source showed a high content of gammaLnn, and there was less biomass compared to cells grown in red light. When the culture was left in the dark for various times, after 144 h it contained about 26% more gammaLnn than in conventionally cultivated cells.
