RIVERA GONZALEZ, Massiel Vanesa; GOMEZ GOMEZ, Liliana; CUBILLOS HINOJOSA, Juan Guillermo  and  PERALTA CASTILLA, Arnaldo. Effect of coal type lignite on growth and production of pigments of Arthrospira platensis. Rev. colomb. biotecnol [online]. 2016, vol.18, n.1, pp.73-80. ISSN 0123-3475.

The Biomass production and pigments from Arthrospira platensis has become very important, because these have applications in food production, metabolites of biotechnological and industrial products. However, for the production of biomass and pigments they have been used various substrates that generate high costs. Growth and pigment production A. platensis under the influence of six concentrations of low rank coal (LRC) type lignite (10, 20, 30, 40, 50, 60 mg / L) was tested against a concentration of AIA (80 mg / L), in batch cultures, performed in Zarrouk medium supplemented with LRC type lignite and AIA, under constant aeration and photoperiod of 12:12 hours, for 33 days. The highest average values obtained in terms of biomass production and pigments were achieved in the cultures supplemented with 50 and 60 mg/L of LRC type lignite with respect to the controls. The results provide evidence of the potential use of CBR as humified organic matter, rich in nutrients for growing A. platensis that could be tapped into aquifers means they are exposed to coal mining, contributing to processes of purification and bioremediation of contaminated waters carboniferous materials.
