“…In the trials with inorganic carbon, max occurred between the fifth and the eighth days of culture. Our max values ranged from 0.04 g L −1 d −1 to 0.17 g L −1 d −1 (Table 1), similar to the max = 0.07 g L −1 d −1 reported for Cyanobium growing in BG-11 media [19] and max = 0.08 g L −1 d −1 for LEB 18 growing in medium containing 10 g L −1 NaHCO 3 [2].…”

Microbial biopolymers can replace environmentally damaging plastics derived from petrochemicals. We investigated biopolymer synthesis by the cyanobacteriumSpirulinastrain LEB 18. Autotrophic culture used unmodified Zarrouk medium or modified Zarrouk medium in which the NaNO3content was reduced to 0.25 g L−1and the NaHCO3content reduced to 8.4 g L−1or increased to 25.2 g L−1. Heterotrophic culture used modified Zarrouk medium containing 0.25 g L−1NaNO3with the NaHCO3replaced by 0.2 g L−1, 0.4 g L−1, or 0.6 g L−1of glucose (C6H12O6) or sodium acetate (CH3COONa). Mixotrophic culture used modified Zarrouk medium containing 0.25 g L−1NaNO3plus 16.8 g L−1NaHCO3with the addition of 0.2 g L−1, 0.4 g L−1, or 0.6 g L−1of glucose or sodium acetate. The highest biopolymer yield was 44% when LEB 18 was growing autotrophically in media containing 0.25 g L−1NaNO3and 8.4 g L−1NaHCO3.

“…The production of polymers from petrochemicals is the second major use of oil after their utilization as a source of energy [1]. Biopolymers can be produced using biofixation of carbon dioxide by cyanobacterium and could reduce both dependency on petroleum and carbon dioxide emissions [2].…”

“…The initial concentrations of NaHCO 3 in 100 % ZM and 20 % ZM were 16.8 g/L and 3.36 g/L, respectively. When the cells were exposed to higher concentrations of NaHCO 3 , photosynthesis could be inhibited due to the fast entrance of sodium into the cell, which justifies the deceleration in cell growth at the start of cultivation in 100 % ZM. Moreover, in 100 % ZM, it is possible to obtain higher concentrations of biomass after longer times without growth inhibition, although the initial cell concentration is lower when compared to cultivation in 20 % ZM.…”

Simultaneous production of phycobiliproteins and carbonic anhydrase by Spirulina platensis LEB‐52

The simultaneous production of carbonic anhydrase and the phycobiliproteins, C-phycocyanin and allophycocyanin, was evaluated during the cultivation of Spirulina platensis using Zarrouk's medium in its non-diluted (100 % ZM) and diluted to 20 % (v/v) (20 % ZM) forms. In both media, Spirulina simultaneously produced carbonic anhydrase and phycobiliproteins. For the phycobiliproteins' production, higher concentrations (mg/g) of C-phycocyanin and allophycocyanin were obtained when 100 % ZM was used. For carbonic anhydrase production, higher concentrations (U/g) were obtained on the 6 th day of cultivation in both culture media. 100 % ZM promoted greater productions of these bioproducts, and, for simultaneous obtainment, the cells should be harvested after 21 days, obtaining concentrations of 137.4 mg/g C-phycocyanin, 104.4 mg/g allophycocyanin, and 26.6 U/g carbonic anhydrase.
