• Abstract:

  Arthrospira platensis is a microalga

  which belongs to the group Cyanophyta; it

  has metabolites such as proteins, vitamins,

  carotenoids and the phycocyanin pigment, all

  of them showing a broad spectrum of biological

  activities. The Zarrouk medium, a chemically

  defined medium, is used for the growth and

  generation of compounds of interest in the algal

  biomass. However, a significative production

  cost is assigned to Zarrouk medium. This work

  aimed to conduct a comparative study between

  the Zarrouk culture medium and the modified F2

  culture medium concerning to the production of

  products of industrial interest. TLC and HPLCDAD techniques were used in order to verify the

  chemical profile of the biomass extracts (MeOH

  and EtOH) originated from the two different

  media and the production of their main bioactive

  compounds. TLC and HPLC results suggest

  that the extractions with EtOH led to a higher

  extraction of carotenoids and chlorophyll, as

  well as of other minor substances. In addition,

  biomass produced in Zarrouk medium seems

  to contain a greater amount of carotenoids than

  biomass produced in F2 medium.
